Tailgate; electric wondow to manual window conversion?

[Psycho71]

Update.

After about three weeks of the window not operating at all, I had to crawl in the back, take my drawer system apart from inside the burb with the tailgate window stuck in the up position so i could get into the tailgate. I disconnected the window so it would lower and I get even get the tailgate open. I got my battery charger, ground it to the motor itself, and used a small jumper to each terminal. it would try to run, but wouldn't travel the arms more than an inch before it would quit. So I pulled the motor, tested it with zero load on it, and got the same results. So I need a new motor, good thing this one has a lifetime warranty.

So I thought I would go ahead and verify that the wiring, switch, and all things were doing what they should before I get the new motor and put it back in. So I connected a small LED indicator light I had left over from a past project. I grounded it to the chassis and connect one of the wires that drives the motor to it. I went up front, turned the ignition on, and hit the switch. The light lit up. I then hit the switch in the other direction, the light lit up again. Not good! So i swapped the lead feeding the light to the other wire that drives the motor, and got the same results when i hit the switch in each direction.

So it appears to me that there is a short between the two wires that is causing both of them to be energized when only one at a time should be getting power. This could certainly explain the random operation problem. I had been through all of the wiring from under the rear of the burb, all the way into the motor, and from the engine bay into the switch. So the short pretty much has to be under the burb somewhere.

I am going out to the shop today to replace the wiring all the way from the switch to the motor. Get a new motor, and give it one last attempt at a fix.

Wish me luck!
