'98 Dodge Caravan, Cooling Fan Won't Shut Off
cooling fans on my 98 Dodge Caravan won't shut off. I have to pull
the fuse to stop them. Where is the switch that activates them?
dont think youll find that there is a switch problem. More
often, it is a controller/module for the cooling fans that has failed.
If you look closely on the inside of the drivers side of the frame/unibody
right next to the radiator youll see a small black box setting on
an aluminum plate that is held by two screws. Its likely that one
of the screws is broken/missing. That aluminum plate is a heat sink for
the fan module. When the screw that holds the module to the frame breaks
there is not enough contact of metal to transfer the heat and the module
fails. The result is fans on all the time or not working at all. Dodge
has an updated module and screw kit to correct the problem.
