You may have checked the engine to frame ground, but there is a ground distribution box that grounds the different sensors and controls.

May 11, 2013 - Uploaded by aeroaggie This applies to 2008 Chevrolet Silverado 4.3L V6 WT models. ...the dash reading "engine hot, AC off"..on a 2007 Chevy Silverado4.8L. ... I have an 09 Silverado and the dealer changed thethermostat under warranty in 2013.

On my 2008 Chevy pickup, the temp gauge would show normal temp and all if a sudden would drop out down to 160 on dash. When this happened, the panel would show ENGINE HOT, AC OFF. I had this problem for months. To reset it, I would have to pull over, take the battery cable off to reset the panel. I finally did some research and found out that the thermostat was the problem! When you replace the thermostat, make sure you get one that is set at 195 degrees cause there are different set points and if it doesn't make temp, the computer automatically takes over to prevent engine damage. I went to Autozone and bought a Failsafe 195 temp thermostat and my truck hasn't had a problem since!

My advice is never go to any dealer

Do you not go to local shops as well

Tellinmg

could be coolant temp. switch

When the ac is blowing hot, is the compressor working when the engine is running ?
Have you checked the system to see if it is full of freon ?

after replacing a thermostat you need to wait till the thermostat opens and re add more coolant till its full. if the lite stays on the sensor is most likely bad

You condensation problem because the fan that cools the condenser will not run or runs poorly if that works and electrical checks if it can be used clucht fan fan problem clucht that the fan does not spin fast enough to adequately remove the heat .. .

no the ac should turn on on hot or cold, also should run whenever the defroster is on

I have the same problem with 50,000 miles.
