>I have a 2001 Jeep grand Cherokee (6 cylinder) with only 45,000 miles. Recently the AC started acting up. I can feel that the air is cold but the ac system is not blowing good. I can hear the fans working harder as I increase the fan setting to Hi, but it hardly blows any better even on hi. If I had to guess some vent or somthing is not opening fully. And of course I tried all types of setting combinations form defrost to recycled air and so on. can you give me some good advice please?

Wipers come on when i start the truck. Radio searches but will not find a station. Engine is missing dealer said it is electrical not mechinal. If i pull the wiper relay & put it back wipers work normal but still go crazy sometimes ? factory radio works sometimes & other times won't get a station. Dealer said its like wipers are getting a command to run from the module not the switch ? engine is running rough .But sensors are working. Anyone had any problums like these ??????

This is a repost because of ommitted information. My jeep is a 5.2 v8 full time 4x4 w/4lo. Automatic. I have checked to see if harnesses are hooked up on tranny and they are. what I dont know is which one is to reverse lights and how to test. there is no power at the light bulb socket. thanks

Bulbs and fuse are good. where can I check next. A location and discription of diagnosis would be very helpful!!
Thanks for the input!

Engine malfunction light has been appearing and disappearing. 2008 has 105,000 miles and dealer said catalytic converter needs to replaced for $1650 and out of warranty at 80,000 miles. Any options to replace cheaper, since I contacted another shop and said they needed to purchase catalytic converter from dealership. His quote was $1350.

I recently purchased a 2001 Grand Cherokee Laredo. It has a large cosmetic disruption in the fender. I have looked all over the net looking for a rear fender none seems to exist. How do you repair the rear quarter panel on this model?

i need a complete, new trans.....how much should i pay???

I have a 97 Jeep Grand Cherokee v8 4x4. The problem has been happening since about 85,000 miles (at 94,000 now). When I'm accelerating from 50-60, my jeep starts shaking pretty bad. It's like it doesn't have enough power. I have to floor it for it to properly accellerate. Once I let off the gas it will start shaking again. This happens ESPECIALLY when going uphill. I've read on nuerous other sites this same problem happening but no one seems to be able to pinpoint it. HELP! I love this car but this problem is really irritating me

My Jeep revs too high when I start it. The idle comes down when I put into drive but there is something wrong. Sometimes it starts okay but mostly revs too high. What could be wrong?

When my 1998 jeep grand cherokee sits in idle, the engine warms up and heat comes out like it is suppose to do. But when I start moving down the road, the temp gage goes down to cold and cold air comes out of the vents instead of heat. I already replaced the thermostat. Could this problem be the water pump? Also I took the radiator cap off and there is no movement of coolant in the radiator.

My jeep wouldn't start. Had it looked at by dealership and they said it could be electronic ignition module. They recommended it be replaced. $900 to fix. I had it back and 5 days later the same thing happened. Now they say it is corrosion of the wires. should they have seen this before they replaced module?
