caseyrstewart Posted June 26, 2017 Posted June 26, 2017 Hey all, I am having some electrical trouble with my Comanche. Two separate issues: 1) I've noticed recently that my headlights will turn off intermittently. If I push the knob in and pull it back out, it typically fixes the problem for a little while, but it always comes back. I've replaced the headlight fuse a couple times as it keeps melting. I'm sure this is somehow related, but uncertain as to the root cause. Any thoughts? 2) My windshield washer fluid won't spray. There's plenty of fluid in the tank and the wipers move side to side. Help! My windshield is getting filty! Thanks for helping a Comanche amateur like me!
Big Dan Posted June 26, 2017 Posted June 26, 2017 As far as the windshield wiper fluid is concerned.. Have you checked the washer motor? It's at the base of the wiper fluid tank. Sent from my Nexus 6P using Tapatalk
cruiser54 Posted June 26, 2017 Posted June 26, 2017 Headlight system only has a fuse inside the headlight switch.......
HOrnbrod Posted June 27, 2017 Posted June 27, 2017 What do you have for headlamps? Standard sealed beams or something else, like halogens?

Big Dan Posted June 27, 2017 Posted June 27, 2017 Test the connection. I think I got around 5 volts, but no sound/anything from the motor. Replaced and had no issues. You should be able to hear the motor running (while looking at it in the engine bay..not in the cab) when you flip the washer fluid on.

SVPete Posted June 28, 2017 Posted June 28, 2017 Thought my washer pump had quit working for years. One day when I finally decided to troubleshoot it, turned out the "T" fitting which supplies the fluid to both sprayers was broken. It is located under the cowling where the wiper motor is located. My wife noticed the water dripping under the truck.... Certainly worth the dummy check.

It's labeled "HAZ/STOP" and it's a 15 amp fuse. Looks like some plastic may have melted off from a former fuse. The prongs look awful dirty and are possibly not making a great contact. I've got to figure this out. It's driving me nuts and is beginning to be unsafe while driving at night.
caseyrstewart Posted July 5, 2017 Author Posted July 5, 2017 Got my wiper fluid working! Pump just needed replacement... Still having trouble with the headlights/fuse. Is it possible to just replace the fuse panel?
