1978 Bronco Liftgate Window Electricals

Rear liftgate window wasn't working from the dash switch or with the key at the liftgate, I start at the begin of the circuit, and test every component in the section of the rear window wire harness to find the problem. #electricalrepair #wiringrepairs #fordelectricalrepair #bronco

Thank you for this video. My rear window is working perfectly now. Bad breaker and a couple bad factory connections. Thanks again!

Thanks Alvin. Good wiring exercise. Chasing electrical issues can be frustrating at times. But no blue air in the shop like the previous caddy job....walt

Thanks Walt, this project was a little more fun to do, it's always nice to get to know how these things work. 😊

Nice job tracing the issue. It's always in the last place I look. If I could only start with the last place I'd save a lot of time.

[@J_R_Shop]

Lol... isn't that always how it goes., just like there is always one bolt/screw that won't come out.

Alvin,
I noticed a huge problem under the dash. Unlike our T-Birds, there's 4000 bundles of wire missing. You best get to finding them, my friend. Meanwhile, good fix!

Hey John,
Yes...a lot less complex than the T-bird, but there are still those pesky vacuum hoses! Lol

I agree with everyone else. Great example of how to chase wires until you find the issue. And it was a small problem as it usually is.

Thanks Matt, this was a good basic circuit to show as an example. 😊

Hello Alvin. Excellent troubleshooting. I thought you would find one of the switches corroded. That set up is very simular to my 65/66 Mercury Colony Park. Is there a safety switch to prevent the window operation when the tailgate is down in the Bronco? I also am looking for a new weather seal for my tailgate, maybe the Bronco is simular. I'll have to look into that.

Hi George,
They are very much the same, and you are correct, that limit switch also prevents use of the window while the gate is open/down.

That corrosion in the connectors can drive a person crazy. Nice trouble shooting.
What about using dielectric grease in those connections? Does that stuff work ?
Thx

[@J_R_Shop]

Thank you Doug, dielectric grease works very well, a little goes a long way to keeping moisture out on those sealed plugs.
