I have a 2001 Jeep Cherokee (100,000 miles) with an a/c compressor clutch that continually engages & disengages. I've spent hundreds of $$$ having the system flushed, recharged, checked for leaks, belts, wiring, etc. Engages/disengages in both the heater and a/c modes. 10 seconds off, 5 seconds on...repeatidly, non stop. Repair man says "live with it". This can't be normal.

Replying to: swamprat2007 (Jan 24, 2007 6:46 pm) I have a 2001 Cherokee Limited with only 55,000 miles and I am having the same problem. One shop said it was normal so then I bit the bullet and took it to the dealer. They said there was an A/C leake and claimed they fixed it. When I got the car back it just did the same thing exactly as you are describing. On and off and on and off every few seconds and it vibrates and makes a deep below in the undercarriage/exhaust. My mother's 95' Cherokee does the same thing. It makes me nuts because I LOVE these trucks. I bought the 01' used because I like them so much not because I couldnt afford a new car. I dont know what to do about this problem either but you are right it cant be normal. Steve |

| My 2001 Cherokee Sport does the same thing. I purchased it brand new on Nov 2000 and wrote it off as normal operation. Never had any issues with the AC performance other than at idle the clutch likes to engage and disengage off more than normal. | |

| I own a 2001 Jeep Cherokee limited edition with 45,000 miles and the air conditioner compressor seems to go on and off, it does not stay on long enough to cool,the mechanic recharged the system but it did not help,I see a few posting with the same problem, has anybody figuered out how to fix this? | |
| On July 12 I posted a message about my 2001 Jeep Cherokee with air conditioner compressor problem ,compressor cycling on and off but not cooling, I decided to do some testing of my own, I just had the system recharge a few months ago, my first test was to unplug the connector to the clutch and wire it directly to the battery, the clutch worked fine so that eliminated it as a source of trouble, my next test was to check the pressure switch mounted on the dryer ,I removed the plug and shorted the contacts and that made the clutch work ,I assumed that maybe the switch was defective as I proceeded to remove it I notice that it was not tight, I remove it and also check the O ring on the conector,and reinstalled the switch, still had the same problem , my next step was to add freon and it worked, it was probably loosing freon tru the loose connection on the pressure switch, I did not think I was loosing freon since the unit was charged recently. I hope this can help others with similar problems | |

| I have a 03 GJC and have checked the relay for the cooling fan and have also unplugged the connection to the fan. The fan continues to run at a high speed when reconnected. What is the cause of this and how do I fix it? The fan has drained the battery dry. | |
