Can anyone help??? PLEASE!
I am from GM Customer Service. Can you please email me more information about your situation so I can look into your concern further? You can get my email by clicking on my name. Thank you,
Mariah GM Customer Service
Did you tell the dealership that the fix didn't take care of the problem? Thank you,
Mariah GM Customer Service
I apologize that you experienced a concerns with your vehicle. Unfortunately, I cannot diagnose your vehicle over the internet. You are going to have to have a service tech look at the problem. I would explain to the dealership that these problems started after they tried to fix the Navigation system. They may help you out with the repairs because of it. If you have any further questions please let me know. Thank you,

1. the blower only runs when set to the max setting.
2. the compressor will not run (for AC or defrost).
The fuses and compressor belt are fine. The compressor was replaced 4 years ago and had always worked great since then.
I could have multiple problems but was thinking of first replacing the Heater/AC controls. Does this sound like a good first step?
Thank you, Bill.
We have two Tahoes ('02 and '05) and an '05 Suburban that have all experienced this before. Turning the engine off and then back on usually corrects the problem. I have also found that the problem sometimes occurs when the Oil Change Light comes on. Resetting the light fixes the problem. (This tells me it is some sort of computer glich.) I asked the mechanic at the local dealer and they "offered" to reprogram the computer for $85 to see if it would help. If this didn't fix it, the next step was to replace all of the damper motors in the dash for several hundred dollars. I have decided to live with the problem for now.
All in All I was NOT happy with the way this was handled. Yes their software update fixed the problem, but why should I have to spend $90 for them to fix their own buggy software?? Then with the other issues: by definition, intermittent means that it does not happen all the time! But instead of even attempting to diagnose the problem they just made me pay for the time it took them to NOT have it happen to them and said "sorry, we couldn't make it happen so we can't do anything about it."
:mad:
Does anyone know how to correct this problem?
Thanks,
95 tahoe the ac control panel(the panel that controls hot and cold fan speek turn ac on and of recirculate if it blows on feet or face etc) completely quit working.
My son and I finally figured out it was the control panel so i replaced it and everything worked perfectly for 2-3 days. Then today it completely quit again.
What is making it do this?
As a side note when the control panel quit the cruise control quit as well. when i replaced the panel the cruise control started back working and now it quit again. the cruise control is on the turn signal
Good luck.
In order for A/C to work, you need the correct amount of freon. Can't be too much freon, or the compressor will not be able to pull down the low side enough, which won't give you enough pressure differential across the orifice, and won't give enough cooling. Can't be too little freon, or won't be able to pump up the high side to a high enough pressure, same results.
Orifice needs to be sized correctly and unclogged, to allow a specific flow through it.
Compressor seals needs to pump up enough pressure, to allow this all to work....and turn on and off correctly via the pressure switches and clutch, to keep the pressures correct and the flow correct.
There are a number of other pressure switches, relays, and other components which are all required to make this all work as designed. This is similar, but a more difficult environment than a home air conditioner....given varying engine/compressor speeds, varying air flow speeds thru the radiator, and the lack of insulation in the passenger compartment.
An A/C shop has the tools and knowledge to figure out just which piece or pieces aren't working correctly, and fix it. A homeowner can't even check the most basic functions without a set of pressure gauges.
Good luck.
Have you had the vehicle diagnosed for the concern? How long has the concern been present in your vehicle? Thank you,

The way you stated your original problem....."The temp gauge on my 07 Suburban stopped working and shuts of my AC, says my engine is overheating, it isn't", is somewhat confusing.
The temp gauge is an 'output' device, just basically giving you information. It would not be doing anything but telling you what the temperature is.
The engine would be creating the heat, or which the waterpump, thermostat, and radiator would then be managing the temperature to the correct range.
The temperature sensor, would be monitoring that temperature, and sending the information to the computer, which would do things like adjust fuel mixture, adjust idle speed,etc, and then tell the gauge what temp to display. Sounds like from what you write, it also turns off the A/C. This could make sense, as the A/C puts extra heat in front of the radiator as well as extra alternator load running the fans, and A/C compressor load on the engine causing it to work harder. If they had the computer programmed to shut off the A/C to reduce engine load, that would make a lot of sense.
The gauge then, displays the temperature to you.
So part of what the dealer needs to do out of that whole bunch of stuff, is figure out what's working correctly, and what isn't. Is the engine really at the correct temperature, or not. Is the sensor detecting correctly what the temperature is? Is the computer receiving that signal correctly? Is the programming using that signal, and making the correct adjustments? And then finally, is the output temperature gauge reporting the temperature correctly.
