  1. Recently pulled my driver side blend door actuator because getting randomly switched to hot. First tried running it without that actuator in there at all and while I was doing so and turned fan up to 4 air started coming through defrost vents in addition to front vents (was set for front vents). Hot air problem was not solved with no actuator so I installed a new blend door actuator (at least I think I did, it was the one to the right of steering column just above a floor vent on driver side). Hot air issue appears resolved but now turning knob to change which vents are active has no effect at all, always get a mix of front vents and defrost vents. Thoughts?
  2. I have a problem with my AC cutting off, as well as my instrument cluster not working. I don't believe it is either of those, as I have found a loose connection near the interior fuse box. It seems wiggling one of those wires, gets both items to work again. I've asked about this at a dealership, and to me that seams like a total rip off - est. $550 for the Instrument panel, and another $500 for the AC blower motor. Any ideas what I can do?
  3. I have a 2003 Hummer H2. The craziest thing.... First of all, the knobs on the climate control unit went berzerk. I ordered a new unit and the temp knobs work great. However the problem still lingers. My drivers side A/C will NOT turn off... I have both knobs on 90 and the passenger side blows nice and toasty but my drivers side is freezing me and it will only blow a/c ! (not vent air) A/C air. I have noticed alot of heat being stuck on but not a/c ...........
  4. I have a 2005 Sierra 1500 Crew Cab that has had 3 AC compressors go out on it. The first blew in July 2011 and was replaced with a new, not rebuilt, AC compressor. That compressor blew in June of 2012 because the condenser wasn't replaced. Replaced the condenser in July 2012, a month after the 2nd compressor was replaced, when the mechanic realized that a simple flush wasn't enough to remove the crap stuck in the condenser where the first compressor blew. The compressor that was replaced in June of 2012 just blew, about 13 months after it and the condenser were installed. All parts were supposed to be new since I didn't want to deal with issues of a rebuilt compressor. Do I have a bad mechanic or is there something else going on? Really don't want to throw another $1000 into a condenser, compressor, and everything else if it is probably going to fail in about a year. Truck has 101k miles on it, so am I needing to worry about other large issues that could come up besides the AC? Thanks for your feedback.
  5. Hi everyone i am a new user who just bought a 2003 gmc sierra 1500 and i have been doing some repairs, but what has really stumped me are the climate controls. The drivers side only blows hot air and passenger side side seems to be only coolish air. As well the a/c doesn't come on at all even the orange lights on the buttons don't come on. So far i have checked the fuses and installed a new head unit but still no change, any help would be greatly appreciated.
  6. I did an engine swap from a 4.8L to a 5.3L in my 2003 Silverado 1500 ext cab 4x4 last week, when I took the old engine out I left the AC system in tact (I just unbolted it from the engine and bolted it back to the new one in order to avoid evacuating and recharging the system) I've got the truck on the road now and have ironed out all the kinks except the AC. For some reason, I can't get my AC to work at all. I checked the connection at the compressor and I'm not getting any power there with the AC running. The fan is working and all lights are working in dash but it's not blowing out cold. I checked every fuse I could find relating to HVAC and they all look good. I also traced the wiring back to the main harness and found no obvious signs of wear. I'm out of ideas, any suggestions would help.
  7. I have a 92 GMC conversion van, 350tbi with dual air, the compressor went out so I put a new one in and have been having issues. The AC was still blowing cool but was getting worse, the compressor had a growl and was unable to get the high pressure into the normal range, so I put a brand new AC Delco compressor in. When changing the expansion valve it had what looked to be pieces of seal in it (the van was converted to 134 prior to my owning it and they did not rebuild or replace the compressor). I flushed the system several times, until the the flush came out clean. I replaced the compressor, dryer, and expansion valve, put oil in, vacuumed the system and then the problems started: - On the back of the compressor the seals to the manifold leaked, the compressor came with two types of seals so I used the ones that looked like the old ones, I switched them with the thicker seals and it held 30psi vacuum. - Once I started charging the system, as I approached 200 on the high side, it blew out the back of the compressor (I think the seals on the manifold). The front was starting to get cold while I was charging it. - I again took the manifold off, and thought that maybe with the new compressor the bolt was bottoming out not letting the manifold seat, so I put a washer on the bolt, resealed it. Again it held vacuum, then with charging it blew at 230 (withing what my book says is normal) it has since held about 110 pressure for several days. The thing that was weird is that this time the rear got cold but the front did not So my questions: I used a "warm weather, variable sized" orifice tube, could this be causing problems? Maybe more apt to clog if there is a little junk left in the system, causing too much back pressure? Could it be a relief valve on the back of the compressor? My next options as I see them: try buying new, thicker seals for the manifold, when I do that checking the orifice tube and maybe replacing with just a standard one. I just don't want to waste any more 134, its getting expensive!!! Thanks
