I am looking to replace my sensor and the harness as they are known to be bad and causing the p0711 code. In my research I found the 2015 has a split harness but they changed it in 2016 to a one piece harness and then I believe they went back to the split one, not sure which year. What is the part number for the sensor and harness? I've looked everywhere and can't find nothing, plenty of threads but noone has mentioned part numbers and acdelco website does not have a part listed in their catalog for that year.. nor does any parts site like napa or autozone
heat issues anyone?
Stacy Crute posted a topic in 2014-2018 Silverado & Sierra Troubleshooting2015 chevy 1500.. 3400 miles. A couple of times the heat didn't work. It always did "next time".. the other day I had to take a 3 hour drive.. it didn't work the whole way there...stopped for an hour..headed back still with no heat (it was 42* so it was not pleasant) Took to dealer - they said they cant find anything wrong, of course, and of course the he was working fine. Its only done this a couple of times in the past 2 months now. Anyone experienced anything similar? It blows out air, and it will adjust the fan speed properly (or what I'm guessing WOULD be properly if it was blowing out heat) based on the temp of the cab. Even when taken off of auto and just turned temp to hi and fan speed up, with AC button off, it was still blowing cold air. Any ideas? Could it somehow be user error? (doubtful) Also when the AC button is on, even when its on heat, is the AC really still running? seems dumb that lights always on even when you have the temp high and its blowing heat.
temp 2003 Chevy avalanche 1500 wheel drive interior rear view mirror
SheilaK posted a question in Ask the GM TechnicianI have a 2003 Chevy avalanche the digital display quite working. I check all the wiring and fuses I do believe, and found no issues except now I can't get the mirror's electrical connect to seat all the way on the mirror's plug. It clicks but half of the connector is still up. Has anyone else had this issue, if so how did you resolve it? Thanks
I did a coolant flush on my 5.3 '03 Sierra and changed the fluid from green to Prestone orange coolant. I had mild overheating issues prior to the flush, so I figured flushing the coolant and changing to orange Prestone might help (I did the same exact thing in my '04 GTO with LS1 and haven't had overheating issues since forever). Now the temp always goes above midway, and here's the thing... It does the same thing even on the HIGHWAY with fans on high speed, and it sometimes goes down in traffic only (basically when I'm not giving the engine any acceleration). I changed the coolant again with dexcool, and did an air bleed, changed the temp sensor and thermostat two months ago, and cannot see any leak from the pump but still nothing is helping. I'll note that the green coolant didn't look dirty when it I flushed it out, and that it only heats up when I'm accelerating.
Hey guys, It been few years now maintaining it... I have 2005 sierra 1500 z71 5.3L extended cab... I gotten it at 80,000 and now it at 182k, i have since replaced the alternator, water pump, coolant hose, flush the tranmission fluids, and now i noticed now it be getting hot while im idling and the oil pressure gauge will be low but when i am driving the oil pressure gauge goes back to middle and the coolant temp will go back to the middle instead being hot... it happen when im going through a stop like a traffic jam... it wouldnt last 5min without getting low oil pressure(although no alarm light) and high engine coolant temp (coolant warning light came on) reaching... i been racking my brain trying to figure it out what could it be... it same thing all over again, driving normal then come to a stop, a long stop then my oil pressure will dip low and then engine coolant will dip pass the 210 mark and get hot til if i am idle long enough it will flash coolant light on... i open the hood check the engine, hoses, coolant level is good, fan blowing, but still getting hot with no leaks or steams... i really love my truck i really need to resolve this asap... pls help???

Good afternoon all, I'll try to make this short and sweet so here's the deal: 1) Gauge Coolant Temp wont respond. 2) I have done the necessary test with the coolant SENDING unit. (Ground out to see if it pegs hot) 3) Used Voltmeter to check for signal to sensor which it has. 4) Checked Fuses. All are good. 5) Rest of gauges work. And here's where I'm stuck. Apparently the 1995's don't use stepper motors? (I haven't taken the cluster apart yet) But if they do, I cant find the right ones. Seem to be for 1996 or 1997 and up models. This cluster does not have a conventional pigtail that plugs into it but rather the cluster "sinks" into the adapter. The circuit board is flexible. Does anyone have any info on this type of cluster? If its a simple stepper motor or resistor I can fix it. (I think, lol) However, rather than replace with a refurbished or used one where the mileage will not be correct I'd rather upgrade to a digital cluster if possible or even swap in a later model chevy cluster. Anyone know if this is possible? One thing ive found out with the 95's is that it isn't very compatible with other models. Please ask any questions that you may have. I look forward to your responses!
2013 Sierra Rising Temp Gauge No AC and No highspeed fan
Michael Lauze posted a question in Ask the GM TechnicianOK HERE WE GOOOO!!! I have a 2013 GMC Sierra Nevada 4.8. I live in Manitoba Canada where for 10 months out of the year it is below freezing! Last week we had a warm day so while my wife was shopping I decided to turn on the AC while I was waiting for her, I got the 3 flash light and it went off, I thought it was because it was to cool still. Than I noticed me temp gauge start to rise. I have owned this truck since it was new and pull a small 5th wheel around with it I have never seen the temp gauge move before. So I sat there waiting to here the fan kick on... It never did, slowly the temp went back down, but within 15 minutes it was back up again. I'm wondering is it possible that a fan relay could be gone and that is why the highspeed fan never kicked in as well as why the AC won't work. I also tried it yesterday and had the same problem.... I'm stumped!
