I noticed yesterday morning while warming up the Jeep in the garage that the A/C Clutch comes in about every ten seconds and stays in for only a couple seconds then goes back off. Over and Over,, even though the AC is not on. Any Ideas??

For now I just unplugged the AC Clutch wire...

 

If you are using the defroster, the AC will run to dehumidify the air.

 

I knew it was the A/C clicking on me. My rig does the same thing in the morning. Someone told me that it was a faulty spark plug wire arching to the block. Nice to know, bout the A/C. Thanks.

 

mine does the samething, the origional owner of my xj had it "unplugged" and something taken out. the second owner wanted the ac put back togather but they were quoted $650 to put it back and fix the reported problem. i got it, and it cost $30 to get it put back. but long story short i dont know why it does it, my mechanic doesnt know why, and nobody i know knows why
the only problem that i have is in traffic when i have stopped and dont have the brakes applied all of the way and it cycles off so there is more power and it jumps forward

I told you about the spark plug, but you were troubleshooting something, and the question was asked differnetly.

If you have the defroster on, the AC will cycle on and off - this has been standard on cars with AC since the mid 70's, if your mechanic does not understand why it happens, FIND A NEW/BETTER Mechanic.

 

Jay said it... if this confuses your mechanic you really need to find a new one.

 

Cool, I just never noticed it before. If it's normal I'll leave it connected.

THANKS !!!

Pioneer, Watch the front pulley on the A/C Compressor, You can see it start and stop....
