In another post I read that the electronic speedometer component was causing AWD problems in some machines. I am wondering what else this circuit is wired into. I know somebody who has a 99 Magnum with a malfunctioning odometer who is also experiencing troubles with the cooling fan motor not switching on. Is the cooling system a part of this circuit?/what else does it control?

Do we have any schematic diagram readers out there?

 

Thor the speedo & the cooling fan are different
circuits.More than likley the cooling fan has a bad thermo switch.The speedo is electronic,meaning
you will most likley have to replace the whole unit.


good luck
