So please help!


The problem has been diagnosed as follows: The fan, the relay, and the temperature sensor are all working. (I changed the temperature sensor for $20). It is most probably the computer module is failing to control the fan. But It could be something else, I am not sure. A new computer will cost hundreds of dollars! I hope this is a common problems in the cavaliers.

Any help is appreciated!

While i was working on mine i bought a switch that plugs into the lighter hole from radio shack. It came with enough wire to reach the fan easily. A little rigging and i had control of the fan. I also had a dealer rig a fan to run any time the key was on. Not sure where they hooked it up though.
