I'm looking for a bypass pulley for the compressor but haven't been able to find, so I was wondering if I just replace the compressor with a new one, do I have to do anything else. The car is stuck in the driveway and I need to kno how to do this the cheapest way possible. Thank for any help.

Hello -

To better assist you is your model the Cherokee Classic, Limited, SE, Sport, Grand Cherokee Laredo or Grand Cherokee Limited... Also please tell me your engine size in liter.

Was your AC working before or did it shell out.

Its a 1999 (but the door sticker says 9/98) Jeep Cherokee Sport 4.0L Staight 6. Yes the a/c was and still is working but the pulley part of the compressor is making a grinding noise when and after the car starts and the clutch(so i'm told) is smoking after driving. Someone has mention the clutch bearing. Is this an easy fix? I've worked on other cars i've had in the past, so I'm hoping to tackle this.
Again thanks for any help!

Hello -

Glad to know it is still working..... If it were me I would change the entire AC compressor with clutch....... The main reason is the compressor has the some miles on it the clutch does. Also you need special tools to work on them. But my main one is the miles on the entire compressor. You may spend about 60 or so, maybe a little more when you match to the compressor... But you can get a remanufactured on for 217 at Auto Zone...

I would also change the dryer.....I would just hate for you to change just the clutch and then a month later the entire system shell out then you have to flush the entire system maybe even change the evaporator etc.....

Thanks for your help. I'm not able to do this project myself due to lack of tools and finding nothing that tells me exactly how to due this step by step. So I'll just shell out the $800 and get done by a a/c shop.
Thanks again 4 all the help.

Hello -

Are you able to change the compressor and dryer yourself and then just have the shop service it? That will save you some bucks?
