Hi Everyone,

So I just inherited a 2nd gen 1992 3.slow 4x4 for the purposes of pissing of the wife (god forbid I should spend time sleeping on the concrete staring at the bottom of the motor instead of with her). It was previously owned by a friend of a friend who is 18 and can barely spell his name, much less keep a vehicle in descent shape.

The exterior, believe it or not, is in great shape. Barely a scratch on the damn thing. Only real dent I can find is the driver side bumper was barely pushed in. Pulled it out with my hand and its basically fixed.

Inside however.... yikes. There is literally a door panel missing, door motor is half gone, and no switches.

This is all fine, I have most of that. I used to own a 92 pickup 3.slo 4x4 so I have a bunch of misc crap from that build.

Splice in that and I now have 3 of 4 working door windows. All door locks now work. So far I'm only into it for a bad switch on the passenger rear side and previously pulled apart (WTF WHY?) door motor & missing switch on the driver side.


This leads me to my main problem, which I will try to explain as best I can and all the troubleshooting I've done... this is about the pass side front window...

initially wouldn't go down or up.
-bad battery
-also fixed driver rear door and pass rear door (although it needed a new motor because it was struggling to get the window up)

swapped battery
-now only goes up.

have (new) motor from rear door - same issue
- pull connectors out of rear door motor and swap polarity
- motor now only goes down
- swap connector polarity again and motor now only goes up


Now i'm desperate. Motor is obviously good on front door. New switch is good. So I splice in rear passenger door to front passenger door. Same exact results.

I compare front connector to rear connector, verify the 2 pins in front match and the 3 pins in the rear match. All is good.

So now I need to know. What am I missing. I understand how the motor and polarity is working with the windows. I understand that they are holding negative until the switch initializes the up or down polarity on the motor.




Has anybody had this happen to them? I'm down to one window. I've checked all I can. I've even checked the wiring harness all the way back to the driver side switch and there is no fouling or shorting.


I'm out of ideas.

I would love some help from you wizards!





I can create a photo account to submit photos where possible. I'm just not proficient with that so just let me know what the best option is.
