2001 Jeep Cherokee Sport, 6 cylinder in line 4.0 liter with a/c Today I noticed that when at idle, the idle speed would increase, and the needle in the coolant gauge would drop down to about 100 degrees. Once the car was moving forward, it would go back to the same spot as always about 200 degrees. Is it the radiator cap? thermostat, a sensor or the gauge the most likely culprit and how simple is it to repair. Any help is greatly appreciated. Franco

First off, thanks for even having this site! So the car won't start a lot more than it would not before. You can hear clicks from the relay. The battery is fine because everything turns on, but the car does not turn over at all. Sometimes, when it does turn over and starts, I get a scratchy sound from the area around the relay. I checked for loose wires and at one time, when my girlfriend tried starting the car, I hear the clicks coming from around the relay, so I kind of messed with the wires and it started. Any ideas? I would bring to a mechanic but I do not have the money to have them check out what could be a number of problems. I read that it could be the relay, but then it could also be the ignition coil, etc. Anybody have any problems like this? ANY help would be great! Thanks! - Tony
