Marauder Wiring Diagram

[Ambitious1]

I am working on my MM's windshield washer pump and defroster and it seems that the issues are all electrical, related to the vehicle's wiring. I believe there may be a break in the wiring somewhere. Does anyone know where I can find a wiring diagram for the MM? Thank you in advance.

Ebay. Search for Grand Marquis and Crown Victoria.

The windshield washer pump is working and I've checked the windshield wiper motor and the turn signal assembly. When I press the button on the turn signal for the wiper fluid, nothing happens. So I think the wiring from the turn signal assembly to the wiper motor has a break in it. I'm thinking the wire diagram will help me figure out which wire is at fault.

Thank you, I'm going to take a look tomorrow and see if this diagram will help.

The wiper module is the more common problem to fail and it will give all kind of symptoms. The wiper module is attached to the motor as one piece, the procedures to test are kinda confusing. So Trying another working one would be your easiest path. IMO

Very true. My washer pump wasn't working,so I replaced it with a working one and it didn't work. Replaced the multifunctional switch and still didn't work. I did some research and found that everything was tied into the wiper module, after replacing the wiper wiper module unit... the works again

If you use a multimeter set for ohms (continuity) with a beep, you can find just about any wire but it takes a real long time. I work on vehicles that have hundreds of wires that are ALL yellow. I have had to alligator clip one end of wire and then go across dash and probe every wire til I found it. Like I said, it is time consuming but is effective.
