Car stalls when AC is turned ON?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.


It can be car battery or alternator issue.
First make sure that your a/c compressor is not seized or stuck. Turn off engine, remove key. Then try to grasp and turn the compressor clutch clockwise by your hand. It should turn freely and with ease.
Next thing to check is your throttle body. If you see carbon accumulaton on throttle opening, Better have it cleaned with carburetor cleaner.But if all this checked ok,then test voltage to the battery and alternator.If any of this gets weak,such stalling problem will be noticed.Because when AC is turned ok,it pulls voltage,if battery or alternator is weak or not properly charged,then vehicle will show this stalling and jerk problem.

Getting this possibilities checked will help.Thanks.
