Sounds normal. The harder the engine and transmission work the warmer they get. The fact that it cools back down during normal driving conditions is great. If it didn't, you'd have a problem.

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.

Removing from bottom is not possible, too many things in the way. If you remove the alternator, the belt pulley and the engine hoist bracket, the compressor should come out the top.

Envoy is running on highway and suddently turn off & wont start


This could be a bad key. Expensive but if necassary to replace to check on the symptom of the car since no codes are being thrown. I would also say check your Idle Air Control valve and your EGR valve to make sure they are working proplery

MOTOR TEMPERATURE


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/.
