Replying to: donza (Aug 09, 2007 12:38 pm) Hi, Donza - Please be sure to reference my Chrysler case number - # 16335305 - when you call in. Maybe we can finally get some heat on them and out of our Jeeps. Be prepared for the worst. Rude rules at their care center; when I asked to speak to a manager, I was hung up on. This is all documented, by the way. I'm prepping to invoke the Texas Lemon Law if necessary.

Replying to: opiek33 (Jul 13, 2007 1:46 pm) Did some research and went and checked to see if the blower motor Resistor Harness was faulty. I found that it was just loose since it is in a place where a passenger can jar it loose by kicking it. That fixed the problem for me.

Replying to: tuggajb (Jul 29, 2007 9:48 am) I have a similar problem that sounds like a vacuum problem. I have a 200 JGC Laredo. The air will not change from front defrost no matter the position on the dial. How do I gain access to the vacuum lines? Are they in the dash?   Thanks.
#34 of 372 A/C Vacuum Diagram Needed by patkell Sep 02, 2007 (1:32 pm)
While trying to fix my a/c proglem similar to one listed in #27 -- except mines an 87 Cherokee with inline 6. Had a leak in the vacuum hose, but since I just rebuilt the engine, I'd like to check that I hooked everything up right. Anyway, if someone has the vacuum diagram for an 87 inline 6, please post.

My 2000 Grand Cherokee Larado just blows warm air. I recently had the water pump, serpentine belt and thermostat replaced beacause the car was running hot. Since then when I turn on the ac the compressor turns on for 5-10 seconds then turns off for 5-10 seconds continuously. I hooked up a gauge and the needle is going up from the green to the blue before the compressor shuts off and recycles. Anyone have any ideas...

Replying to: tuggajb (Sep 08, 2007 10:28 am) If you mean the blower fan yes it blows ok, if you mean the radiator fan, I think it's a clutch driven fan it runs ok whether the ac is on or off.. Replies to this message: tuggajb (Sep 09, 2007 6:20 pm)

#39 of 372 99 jeep cherokee loud squeeling noise by pgjeep Jul 25, 2007 (2:17 pm)
I have a 99 cherokee sport, 4wd,with the bigger engine. Everytime I turn on the air conditioner, or even the vent. It makes a screaming sound like I need a new fan belt, but I don't. It also makes the screaching noise (sometimes when I start the jeep) but not all the time, unless it's cold out, then it does it all the time. the fan belt starts sqeeling, like I need a new fan belt but it is new and I also have a new radiator, water pump, thermostat, and have had the fan belt checked to make sure it was on correctly, and it is. What else can it be? I was told possibly the ac compressor, or maybe the pulleys. SOMEONE PLZ help me. Replies to this message: tuggajb (Sep 09, 2007 6:26 pm) xjman (Sep 12, 2007 7:03 pm)
