The a/c will run based on the pressure switch adn has nothing to do with the temp of the vehicle and or the engine.

If the freon is low initial stages you will hear the clutch clicking on and off and when it becomes extreemly low will not engage the a/c clutch at all/.

Why does my2004 gmc envoy xl slt idle high at startup?


This is normal. All vehicles idle high at start up to get the engine to operating temperature. This is known as open loop. The computer ignores signals from O2 sensors to keep your engine running safely. Once it has warmed up, it will enter closed loop, and you will see a decrease in idle.
