First off, yes, I searched lmao but I can't seem to find what I'm looking for.

When I got my truck home, everything seemed to work okay, but over the last few days, I've noticed the passenger window only works intermittently. For example, it wouldn't work at all last night, but when I pulled the passenger trim panel off and tried it this morning, it worked just fine. Put everything back together and it hasn't worked since.

It will either work on both switches or neither, so it can't be a bad switch. There's no sound coming from the motor when I press the switch, so it shouldn't be the regulator or the gears. I took the speaker out on the passenger side and tugged all the wires to see if any were loose or broken, and couldn't find any. The connector at the motor is good too.

Any other ideas? The driver side window works just fine btw.

 

Motor is a DC motor so + and - are just reversed to change motors direction of rotation.
If possible pull connector and put digital volt meter on connector, set for DC volts, like 20vDC setting.
Turn on key and work the button.
It should show +12v and -12v depending on if Up or Down was pushed.

Common place for a wire break is in the door jamb boot, where wires have to flex, so open and close door while testing.

Bad connection could also be in the motor itself.
You could try tapping the motor while pushing the button, but it is most likely a brushless motor so might not show a problem that way.

 

Did a bunch of testing today and narrowed it down to the switch going out

But now I've discovered a new problem....

When I drove the truck around town last weekend, everything was working fine, but today when I drove up the road to my grandparents' house I noticed that my blinkers weren't working. Neither are my brake lights. I'm blowing fuse #13 (brake position) whenever I press the brake pedal, and fuse #21 (flashers) when I use the driver side blinker. The passenger side blinker won't blow the fuse. The fuses blow instantly.

I've tried unhooking all of the bulbs and replacing them one at a time but still blew the fuse. I can't see any frayed or broken wires, but I know there's a good possibility that there could still be one somewhere. Also checked the trailer plug connections. Any other ideas?

 

don't you have those led tails off ebay?

 

Yep

 

Possible internal short?

 

That's pretty much what I've narrowed it down to, which really sucks because I don't want to have to pull all the wiring out to find it.

 

I mean internal in the tails.

 

Oh, I guess that could be possible too. That would mean one of the soldered connections on the board came out. That would be a pain in the *** to find and fix because I'd have to split the housing.

 

unplug the passenger tail and see if it still pops fuses

 

Actually I did do that in the midst of all my frustration, so it can't be the tails.

 

maybe its the stuff in your dash that you did. Third brake light maybe?

 

That's the one light I didn't check. I'll unplug it next time I get a chance and see what happens. I left my truck at my grandparents house and rode home with someone else so it'll probably be Monday before I get back out there. We went through about a dozen fuses trying to figure out what the problem is.

 

The stuff in the dash as in the gauges? They shouldn't be in that circuit, except for the LEDs I used as my flasher indicators. If my passenger side works, then the LED on the driver side shouldn't be the issue. That's why I think it's a short in the line.
