A/C doesn't work well at idle, but AWESOME when driving

Any cure? When driving my AC is ICE cold. When at idle, its warm.. ;O(

You need more airflow through your condenser while idling. Do you have an engine-driven fan or electrics?

I have the same problem. This is the main reason why I'm considering upgrading to Electric fans.

I have the same problem on my '03 Denali. I was told the clutch fan (fan clutch?) had to be replaced.

If the clutch on your fan is worn, then it wont fully engage and allow the fan to spin full speed.

Yeah, its a clutch fan ;/ Can anyone tell me a good place for a new one? Maybe that will help my engine/coolant temps as well!

 

[jmyler]

sounds like a good time to upgrade to electrics

I got my clutch at napa for $45, i think retail is like $100 tho

just solved that exact problem. turned out my rad had a small crack in it, so it was not cooling proper, so i replaced the rad and now everything is great again, ice cold ac at idle too. but i dont have clutch fans i have efans from factory
