2008 H3 AC OFF Indicator

[Gadsden]

Hey guys,

Forgive me, I did a search but didn't turn anything up..(Maybe I'm doing it wrong). Anyway, I periodically get an AC off indicator, shortly after the engine light will come on. It might stay on a day or two.. Then turn itself off.

Can one you guys point me in the right direction? Off the top of my hat I'm thinking thermostat, but haven't looked into it yet.

Thermostat is causing the AC off. Had mine replaced.
Now the Check Engine light was my EVap vent.
Hope this helps.

If you're getting a CEL then I recommend checking the codes since they may point you in the right direction.

Next time it happens (AC OFF message), look at your temp gauge. If it is not reading, turn the truck off, then back on. Should solve the issue. My temp sender occasionally "hiccups", and then the gauge stays off, and the AC OFF message appears.

Get a scan tool and log the codes. Without more information it’s a guessing game. The last time my GMC displayed A/C off, engine hot, the thermostat was bad- replaced and cleared codes w/ no issues. Best of luck.
