2002 JEEP LIBERTY A/C

RFBRENN on Tue June 01, 2010 10:49 AM User is offline

Year: 2002
Make: JEEP
Model: LIBERTY
Engine Size: 3.7L

Hi, I have a 2002 liberty limited with the 3.7L. My A/C compresser siezed last Sept. and I replaced it. I did not use it much until recently, The system pressures are all good but it blows really cold for about 15 minutes then it blows warm air. If I turn it off for 10-15 minutes it blows cold again then warm. Has anyone else had this problem?

Sounds like you may have a restriction in the a/c system. You will need to get some pressure readings and repost them for a better prognosis. Replacing a compressor with-out replacing other parts and flushing is a big No-No.

I Vacuumed the system out, the clutch went on the old one. I just came back from the beach, it worked for 15 minutes stopped, worked for 10 minutes, blew hot air again then worked the rest of the ride home(1 1/2 hours.

Well you could have an electrical problem witch may have caused the first compressor clutch to fail. You need a constant 12+ volts to the clutch coil when it is requested. You will need to check all connections, relays and fuses as well as the battery terminals. Most people fail to take care of battery posts for corrosion.

You can get the eAutoRepair for your car to check the electrical.
