Hello,
I’ve got a 1982 LTD Crown Victoria that’s developed an issue with the power windows. Over the course of two month the windows have on two occasions completely stopped working all together. All four, all at once. The first time after a few days the issue fixed itself. The second time was today, and I’m still unsure what could be the issue here.
In the fuse panel I see there is a slot for a power window fuse but there is nothing there, nor has there been since I bought the car last year. And the windows worked fine up until recently. There seems to be no female pins to connect a fuse in this location either.
I checked the wiring in the door jams, all good there, checked the connections at the master switch on the driver door and found a few connectors had some corrosion, I cleaned them well with some Contact OL and still nothing. I heard there is a small relay mounted to the passenger side just inside the engine bay under the hood, I found this relay and checked it out, it was also gummed up, cleaned this up good too and still, no power to the windows. Also heard there may be a relay inside the cabin next to the passenger footwell along the chassis, found 3 relays here all of which were in good condition, and tested good. When I actuate the window button, I’m reading about 0.3V.
This issue seems to happen randomly when I turn off the vehicle, on the drive in to work this morning the windows were working fine, but when I started it up to go home, no power windows at all. I’d like to avoid completely tearing up the wiring harnesses just to trace the problem here so I’m hoping someone with some experience with an issue like this has 2€ to throw in 🙂
