  1. I have a 2003 Suburban Z71 that I just converted to electric fans. I used a factory wiring harness that I found on ebay, and the fans turn on when the temp hits 190. The truck was tuned by a popular tuner, but the fans will not kick on with the A/C compressor. I have wired in both wires to the pcm connectors. I cannot for the life of me get it to turn on with the A/C compressor. Could it be a bad relay? Could my 2003, not be able to control the fans when the A/C kicks on. I have fried my compressor, and would like to get this figured out before spending money on another. Does the tuner need to turn on the capability for the fans to kick it on? @JennabearI didnt use your tunes for this as I had another option at the time, but I need some answers. If you guys can turn it on, then you will have my money today. Anybody else have any ideas?
  2. 2009 Avalanche 1500 - Kinda odd - the compressor never turns on when the 'fresh air' light is on., Pressing the recirc kicks on the compressor. Doesn't get really cold though. low side at about 45, high side at 195. Wondering if I have more than 1 issue. Lines get cold, seem fine. Lots of condensation - when sitting in humid conditions plenty of water coming off the lines. Plenty of air, just not ice cold, only when in recirc mode though. Wondering if maybe blend doors are partially open so not doing a full recirc. Driver and passenger side are both the same temp though. Any ideas?
  3. 2018 GMC 2500 - I haven’t driven the truck in two weeks. Got in this morning and the AC was blowing hot air in the full “Auto” setting at 67 degs. Adjusted it down to “Lo” and no change. Put it in manual mode, front vent and high fan speed and it was so cold it fogged up the windows. Any ideas? Dealer had no clue and said they haven’t had that issue before. Thanks in advance.
  4. Highway speeds in recirculation mode I hear a whistle in my 2019 Silverado WT. Turn recirculation off and it goes away, turn it back on and the whistle is back. Anyone else?

  6. Good Evening all. apologize for the novel but bear with me...I need a hand troubleshooting before the local dealer takes me to sizzlers. 2006 GMC Sierra 1500. Dual manual Climate controls. Crew Cab. 5.3 Liter. I have an issue with the air conditioning ceasing to cool while driving after about 20 minutes (what seems). The only way I can get the truck to start cooling again (compressor to re-engage) is if I restart the vehicle ( or if I plug in the OBDII Code tester, more on that later). I have taken the vehicle in for service twice. Once to check the refrigerant level which was fine. Second time they replaced the low pressure cycling switch off the dryer/accumulator (which seemed to be a common fix according the internets). All with no joy. I have a OBDII scanner and it shows no codes. Today I made the connection that the compressor seems to stop when I bring the system off full dual cool to a warmer setting where the truck should be trying to maintain a cabin temp instead of full blast. Once all the fans slow down is when I seem to lose the compressor and the cooling even if I try full cold again. I repeated this failure while driving 3 times. However, while parked this issue doesn't seem to happen cycling the full cold to warmer.. cabin maintaining and back to cold. Very frustrating. Final note: while checking the last time while driving and the compressor had stopped I brought it back to my garage... plugged in the scanner prior to restart to see if a code had popped. When I plugged that scanner in.. the truck did its normal thing being tested (kinda a flash on the dash).. however it also "reset" the compressor and it started again... and cooling like a champ without a restart. So in a nutshell this is where I am. Refrigerant is good. low pressure cycling switch is new on the accumulator. Lose the cooling/compressor when the cabin is not full blast and maintaining cabin temp. Restart will bring compressor back to life or plugging in OBDII scanner. So pretty sure the mechanical side is good. What is next to check or replace? HVAC control head? check another sensor? Please help. Sorry about the novel.. but been at this for a while. Hagendaus
  7. Good afternoon guys, So the AC compressor clutch on my 2015 Silverado 1500 LT, with the 5.3L V8 Flex engine just seized and snapped the belt. Time for some repairs. As I am out of warranty I was hoping that you guys could give me some assistance on the parts that need to be changed so I get this right the first time. By the image below (from GM Parts Direct), what number parts should have be ordering to complete this repair successfully the first time. I know I need #19 (Compressor) and #1 (Condenser assy). What other parts do I need? Also, I'm having issues finding AC Delco parts at a decent price. Would a Denso AC Compressor work just as good? Would a Keystone aftermarket Condenser be just as good? What Santech AC Ring Kit would I need? My thanks in advance guys!
  8. Has anyone experienced a similar issue? I have a 2019 Silverado trail boss and when you turn the fan on, whether it’s ac or heater, there is a noise that is not normal. It comes from the passenger side inside the dash area. It’s not a loud noise and if the stereo is on you won’t hear it. It sounds like the fan motor is off. I wouldn’t bother taking it in if all trucks made the noise but they don’t. I had the dealership take me in another trail boss and there was no sound, just normal wind sound. They changed a bearing saying that was the issue but it is still making the same noise. The second time I brought it in they said they are reporting it to GM. I brought it in today and the service desk worker said it’s “normal”. I asked why the others don’t make the noise and he said it’s “normal”. Obviously not normal or they would all make the same sound. Anyone know what it is??
  9. Trying to determine what is the "normal" max A/C temperature for a given temperature range. In my car, the AC blows at 33.4* when ambient temperature is 76*. The truck blows just a hair over 44* in same ambient temperature, same location, same time, both in the shade. Method of testing: vent speed on low, side vents turned off (test from center console vents), temperature set to "lo" on both dials, recirculation enabled, vent direction on face only. I tested with a digital, instant thermometer rested in the vent for 10 minutes and recorded the lowest temperature and average temperature. I also turn it up to 75 and back down to lo to rule out possibility of a sticking mixture vent. The truck seems like it can never fully cool and it appears the ac is just slightly out of spec. The attached photo is a performance temperature chart for a Honda Accord but should more or less be the standard. The car met the standard, but the truck is on the "high end" of normal. 2018 Sierra 1500, 6.2 SLT with NHT What temperature does yours read at? For those of you who had to have condensers replaced, what is your AC temperature reading now? TIA!
  10. Hello All, 2014 Silvy and no AC, I have read all this forum seems to offer. My system is so low I couldn't just get dye in to confirm the leak, compressor wouldnt kick on. Im going to pull a vacuum to confirm the leak, then charge it that way since the vacuum should get me a jump start on getting the system to take refrigerant. Then find the dye with a light, I suspect condenser, but want to confirm before buying the part. Question for those of you who have done this. Did you add oil on this initial charge to get dye in, to protect the compressor? Or did you only add oil in after the fix on the final charge? If so, how much did you add each time. I've read 2 oz for a compressor replacement, but not how much for a condenser. Thanks, Josh
  11. The a/c on/off and blower position display on the mylink screen started rapidly flashing on and off. The air won’t turn on, it just acts as though it’s turning off and on very fast but on screen only. What would cause this? Any ideas what it might be? Thanks.

  12. About a month ago I purchased a 16 Tahoe LTZ with 37,000 miles. My driver side seat cooling works great on both the seat and the backrest. But on my passenger side I noticed that the seat section does not cool at all only the backrest is cool on that side. I’ve compared it with the driver side and I’m convinced there is an issue. Can anyone provide some insight as to what could be wrong? Are there 2 separate fans for the backrest and the seat? What should I look for and try before I take it in for service? Thanks in advance.
  13. Alright- high Miller here- 445 KM, (276000 miles) tranny rebuilt at 350. in the past month, I have noticed a rattle. Not steady, inconsistent, It is not- piston slap- present when engine is warm lifter- inconsistent lifter gone- zero power loss, truck runs great, drives great, no loss uphill. highly doubtful cat converter. Possibly AC clutch? Bearing in that area? It sounds like it’s coming from that area. Truck straight on, bottom left. I cant test because of GMs safety feature with the outside temp gauge on AC and stopping it (3 blinks) (Canadian winter) Has had anyone just cut this belt and said eff the AC? I have zero use for AC, summer I roll the windows down, I think it’s a waste of gas to be honest. Been through pretty much everything else. More of a nuisance then an issue. Truck drives great, no lights, nothing. Mileage dropped a bit, but could be Canadian winter. Im tempted to cut the belt, as it appears it’s got its own belt and from diagrams that’s what I can see. Thoughts? Tia
  14. I have a 2014 GMC Sierra SLT Crewcab, 2 weeks old. I have noticed that when I have the air recirculating in the cabin, outside air closed off, I still am smelling outside air, cigarette smoke from the next car while sitting at a light, bus exhaust, skunk smell. I also have a Buick Enclave ('11) and my old Silvefrado ('03) which did not permit outside air from entering the passenger cabin when the 'recirculate' button was in use. I is almost like the 'door' is not closed completely. Has anyone else experienced this?
  15. The A/C belt in my 2004 Silverado 1500 4.8L snapped recently, and I believe it’s because one of the pulleys seized up. 2 days before the truck was making a relatively loud screech from the engine compartment at startup. The belt was a gator-type and installed on 12/10/17. I’m not an expert at engine repair, so what pulleys drive the A/C belt? And if one of them is truly seized, how do I properly fix it?
  16. 2001 Chevy Silverado Over the months I've noticed the AC getting warmer and warmer. Now it is barely colder than outside (which is about 100f). Details: Compressor cycles on/off; about 3 seconds on and 7 seconds off. I have attached a recharge can to the low side plug. The gauge reads~100 PSI (truck is at ambient temp which is ~65f). I have parts in the mail to convert my R12 manifold gauge to R134a connectors. I have no high side PSI value at this time. With recharge can connected to low side valve and with the truck running with max ac (again ambient temp at 65f): When the compressor engages, the low side gauge goes from 100 PSI to 5 PSI in a matter of 3 to 4 seconds. The compressor disengages. At this time, the low side PSI slowly raises back up to 100 PSI which restarts the compressor shortly after and the cycle goes on... Any takers on helping me or giving me possible causes (and what to do about them)? I have a nagging suspicion that someone slapped a recharge can on it and overfilled it. This vehicle is driven by 5 different people; no one fessed up so far... Have to wait for parts to test high side PSI. But I'm also worried that the low side pressure dropped so fast; I feel this is not normal? Thanks for the help!
  17. The air conditioning compressor failed on my 2015 Silverado a little after a year of buying it new. I just turned it on again for the first time after winter and nothing, it doesnt even sound like my compressor is engaging. The heat works great, no ac at all. I really enjoy my truck and am a big Chevy fan, but the expensive ac repairs are unacceptable. Are ac issues a common Silverado problem?
  18. After replacement of a dead battery, the driver side AC circulates between Warm, cool, and Cold approx every 90 seconds while the passenger side works properly. Based upon research, it seems that this is a common issue and that fixes may be to 1) initiate a re-calibration using a scan tool 2) perform some steps that require removing a fuse, adjusting the temp, shutting the truck off, etc. I've done each of the recommended procedures, however I am still experiencing the same issue. We also tested the Ac unit for leaks by draining the Freon, measuring the capacity, then replacing it back into the system. The Freon level was at proper lbs therefore proving no leaks in the AC system. Any idea's of what may need to be replaced to resolved this issue or other steps to try to rectify the issue?
  19. My ac is blowing cool air but not getting cold as it use to get. Also notice that the radiator fans don’t spin fast anymore. It come on but it goes really slow. Engine temp gauge normal. Anyone can help me with this?
  20. Just thought I'd share this letter I recieved from GM Canada today. I don't have this issue but I hope it could help others that paid for a repair in recouping your hard earned cash on an obvious manufacturer defect.
  21. I have a 1999 GMC Sierra 5.3 L.When I am driving down the road at 60 to 75 miles per hour the temperature gauge will read around 190 degrees when I turn on the air condition after a while the temperature gauge will start to climb up to about 230 to 235°. Then I will turn the air-conditioned off and the temperature gauge will slowly go back down to about 200°. Can anybody tell me what check for to take care of the temperature problem. Joe

    New Condenser

    Showing the way the transmission cooler is attached to the AC condenser.
  23. I'm posting this for my Brother, 2010 GMC Sierra Z71 Extended Cab. His A/C recently stopped working. When he presses the button it flashes three times and does nothing. The other day he was able to get it to work but it stopped working again and doesn't know where to start looking. Any Suggestions or common things to look for first?
  24. Hi Everyone, I have a 2014 Silverado V6 LS. Last week my AC went out for the second time. Truck has 44K miles so is out of warranty. The first time they replaced the defective hose issue I have read about. I have not diagnosed the latest problem yet but was planning on doing it this week. Then today, I was running errands and I heard a loud squeal and seconds later I had no assisted braking and had to really push down to stop. When I got home I looked in the engine and saw the belt had snapped. I purchased and installed a new one and fired up the truck. The squealing was loud and when I looked the vacuum pump was frozen and the belt was just spinning on it. I also noticed 3 days ago that the electronic thermostat number was stuck at 51 degrees most of the day even though we are in the mid 80's in Dallas. Either this truck is having a really bad week or there is a connection. Any ideas?
  25. Ok, so either I am a little slow (very possible!) or I am missing an important step...my '08 had the remote 'synced' to my truck...and it would recognize when I (my remote) unlocked the doors and my wife's...and it would adjust the seats to the person...when you use the remote start it would recognize the outside temp and if it were cold outside, it would turn on the seat heaters... When I first got my truck, I synced my remote so it does recognize me as 'Driver 2' and my wife as 'Driver 1'... Now, I went to my settings and worked through all the steps I found in the owners manual, my truck still recognizes me, but it will not automatically move my seats back to my position (if my wife drives my truck) and it won't turn the cooled or heated seats on... Again...I know this is first world problems and all...but I figure if I have the options I paid for, I want them to work... Any advise? or are there some key steps the owners manual left out that I need to go back and try?
