I have a 2002 jgc overland. My heat or ac does not work. The blower works fine, the thermostat is ok, as well as the heater core. I believe the problem lies in the vacuum system. The flaps that open to allow the cool or hot air to pass through are not opening. The heat didn't work for 2 months and then worked for 2 days, and now hasn't worked for 8 months. The temperature of the air that blows is accurate with the temperature outside. I have taken the jeep to three different mechanics, and not one of them could figure out the source of the problem. Any suggestions? I'm freezing my ass off.

There are known problems with the blender doors failing on WJ Jeeps with the dual zone climate control. See WJJEEPS.COM.

try tracing down all the small vacuum lines. pay close attention to the ones that run under the battery, make sure they dont have any breaks in them.

1994 cut off.

My 1994 5.2 just did this today, I turned it on it idled smooth for about 10-15 secs and cut off. No sputtering no "stalling" just cut straight off, as if I had turned the ignition off. And it will not start back, it turns over just won't start. I haven't had a good chance to look at it yet and am just looking to find the best place to start. I believe it to be an electrical problem, be it a fuse or relay or short. Dunno yet. Any ideas?

The problem could be the ECM (Engine Control Module)which is located on the right side of the engine near the distributor. It will be sealed in black rubberized epoxy. This is a sealed unit and cannot be repaired.You need to get a code reader to verify what code comes up. That will point you to the problem area. The other cause could be your timing chain or belt since it will no longer start.
Cost for replacing timing chain or belt $350.00 approx.
Cost for replacing ECM (new) $650.00 (junkyard) $200.00
Since your vehicle is a 1994 and depending your mileage and how frequently you change your oil, I would suspect the timing chain first. ECM rarely fail. I hope this helps.

Timing chains are also a almost never fail item. If you did not hear any unusual noises when it shut down I would be more likely to suspect an electrical problem.
