When idling in driveway, turn ac on high and car dies. While driving, turn on ac and motor tries to stall. Is it the ac unit?


Asked by Jun 06, 2013 at 10:10 AM about the 2002 Ford Explorer XLT

Question type: Maintenance & Repair

Runs fine with ac off. Current weather is over 100 degrees outside.

check the throttle body and idle air control valve. carbon build up can restrict air flow and once more load is introduced from the a/c compressor then it may not be enough air flow to keep the motor running.

Start the engine and have someone watch the AC clutch when you turn the AC on. You may have a compressor, clutch or bearing failing. Then I'd look at what kbro suggests.

Krso is probably right on. My 2003 was acting like that at idle, without the a/c on. Cleaned the throttle body completely and it stopped the problem.


Tracy was correct. It was a failed compressor. Been replaced and running funeral.
