Hey guys, so the last hot day of the summer and my A/C won't come on. The snowflake just blinks.... Apparently, this feature is to protect the compressor on below freezing days. So I order the A/C ambient temperature sensor. Not to be confused with the ambient temp sensor for the outside temp on your dash. Problem is, I can't find it.... Anyone know where this sensor is? It has to be outside the engine bay, like the other Dash temp sensor, but no luck. I figured it would be in front of the rad like the other sensor?? If you guys could help me out before april comes

That's a sensor for the refrigerant temp.
I think my original thought may be off. I thought there were two outside temp sensors. One sensor for you outside temp in the instrument cluster and one outside temp sensor for the A/C to protect the compressor from freezing temps.
I found this in a thread. I'll try it after work if its above 40 when i leave
Press the AC & Recirculation buttons simultaneously with your index & middle finger. (The recirculation button is right above the AC button). This causes the an instant temperature update to your system and allow your AC to come on and stay on afterwards. My Chevy service rep. looked up the problem on his GM computer while I stood there, then he printed this solution off for me.

I'd sure like to see that service rep printout. Might be something new but I have parked in cold weather lots of times and the compressor works fine. Might be a "new idea"
to save on gas for the fed fuel standards...maybe. I am gonna find out sooner or later. I trust dealerships about as far as I can throw them, which aint far..
