Got my Sunday best soaked today

[Blish]

I have a slight problem with my MOPAR today. The old girl let me down in the rain when the window wouldn't come back up. I have no power to any of the switches in the car. The circuit breaker works because the door locks work. What can cause this? Thanks!

Do you have a wiring diagram for the car?

 

[Blish]

I found a wiring diagram but its kinda sketchy so im going to poke around with the switch. I need to find the feed wire to the switch and then all the ones that go to the doors and the negatives and positives and the body ground... theres 10 wires to play with.

If someone knows which wire is feed and ground that would be very appreciated because the wiring diagram i found us for a SIXTY SEVEN and mine is a SEVENTY SEVEN

TAN IS FEED! all the wires towards the door are positive polarity and all the ones away are ground and negative polarity. When fed positive to the negative polarity and negative to the positive it rolls the window the opposite way... like a standard car window motor.

Aka I figured out windows on my own. Hope this is helpful to somebody. Bad feed wire.

So, is it now fixed?

Sort of. Need a new source of voltage to the switch

Broken wire? Did you check for continuity?

 

[Blish]

No power or continuity. Idk how the system works or where the keyed ignition comes from

I can break out my FSM and look if you need.

That would be very much appreciated as the book i have in the shop is about as good as a bunch of papers I could roll blunts with that information is just so inaccurate

Will do, stand by. For some reason I doubt a broken wire and the issue is probably somewhere else.

You might find some information here.There are manuals you can download. I see the newest is a 72 but often the wiring is similar between years. (power feeds and wire colors etc)

The window lift relay is powered by fuse #2 (5amp) this gives ignition switch power to energize the relay when the key is turned. May just be a bad fuse.

Check there and report back.

Fuse is blown. My owners manual says it just powers dash lights but thats a lie because the window works!

 

[Mr C]

FSM is far more detailed than the owners manual. Glad it was a simple fix!
