    Default Car sputters when AC fan turned on.

    My friend has an 01 ZX3 and when he turns on his A/C his revs drop down to about 450-500 when the fans turn on and the car is idling. What could be causing this problem?. Another thing is, his car starts to heat up when the A/C is not on. If anyone can shed some light on these 2 problems I would appreciate it. Thanks.

    if the car is heating up without the ac on then that probablly means the other fan isnt working.

    the idle dropping could be related. typically the IACV opens further when the ac is on so that the engine can maintain its idle speed under the extra load of the AC compressor.

    Both fans are working when the A/C is on.

    does the other fan come on at all when its idling but the AC is off?

    No, it does not. I revved it for a while last night waiting to see if it would come on and nothing. Tomorrow we will check the main fan relay and see. I'll be testing a few options tomorrow with my foci and see if we can get to the solution. Keep posting possible solutions. Thanks.
