  • 1991 DODGE CARAVAN
I have a 91 dodge caravan, 140k miles, not sure on engine size. Recently my van overheated. We found that the radiator fan was not working. Our mechanic friend said to check the back license plates lights and that could be the problem. We checked, they were out and we replaced them, which did not fix the radiator fan. Then we found out I have no rear running lights when u turn the lights on. We have turn signals, and brake lights but no running lights. This is really confusing my husband and I. Could someone please tell me what could be wrong? Thank you.

The temperature sensor is more directly connected to the fan than the taillights! Take the bulbs out and change them. There are 2 filaments in them 1 for brakes and 1 for the lights. Is the fan still not working?

Yes we replaced all of the bulbs in the tail lights but still the fan doesn't kick on. I know its a strange problem so to speak because the fan shouldn't have anything to do with the tail light. Right? We are in the process of looking at the wiring to see if something went bad there also. Thank u for any help that u can give us.

Do you have a test light? Try unplugging the connector to the fan, connect either a voltmeter or test light and see if there is power when the engine warms up. if yes the fan itself is ng!
Or you could test it by a length of wire fro the battery, see if the fan runs...

If you are up to testing the multifunction switch, here's how! If it's good, there's probably a bad wire!

Thank u so much for the info and helping us. After carefull inspection of the engine compartment we found that a wire bundle attached to the driverside had completely burned up. I must have had a small electrical fire that did it. Not sure where to go from here.
