    a/c shuts off by itself - comes back on by itself. I'm told there is a short somewhere.

You need to buy a new blower fan resistor. It's located under your glove box.

1998 GRAND CHEROKEE BLOWS ON DEFROST ALONE


Hi I have a 2002 JGC ltd and it is most likely your dampeners or louvers located behind your temp controls (inside the dash) for driver and passenger sides that control the direction of air flow from air outside in, circulation, heat to windshield, centre and or to floor etc. I had a friend that had heat only to the passenger side and cold air blowing to driver side. He took it in and they replaced stuck dampeners and it was not cheap. Sounds like the tipical problem with heaters.

My 2002 grand jeep cherokee is blowing out hot air on passenger side and cold air on driver side can u help also the heated seat on driver side has stopped working is this linked


Thats your blend air door. . .I had the same thing with my 02 Grand Cherokee and I think ALOT of other people have as well. I took it to the dealer and ended up costing right around $800, because they have to pull the dash apart to get to the blend air door.

I already changed the thermostat on my 2002 Jeep Cherokee and the heat actually seemed like it was working but now it is not blowing any heat at all. What could be the problem?


Air in the system or a clogged heater core. If it's air in the system, it needs to be burped. Click on my screenname, go down to Tips and Tricks, and follow the tip there on how to do so.

If the heater core is clogged, you'll need to blow it free. Follow the two heater core hoses from the firewall out to the engine. Disconnect them both, put one in a bucket, and use the blowgun attachment for an air compressor to blow into the other one. Then swap - put the one you blew into, in the bucket, and blow into the one that was in the bucket the first time. Reconnect the heater core hoses, and burp the system (again, follow the Tip instructions for that). Usually that will take care of it.

2002 Grand Cherokee heater warm on drivers side cold on passanger


generally this is caused by a "blend door " motor (actually a vacuum control) not working. I don't have a diagram on this but if you watch the motors mounted to the heater box under the dash, and operate the control, you likely will find one not moving (check all positions including a/c)
