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?

My coolant light keeps coming on 2002 jeep grand cherokee. The radiator is full and the over flow tank is full. The light stays on even after reseting it. At first it only came on once in awhile. And stayed off when you reset it til one of the doors to the car was opened and closed. Then the light would turn back on.
