Window motor fuse keeps blowing. No Ground. Damaged door harness wires.
Window motor fuse keeps blowing. No Ground. Damaged door harness wires.

WINDOW GOES UP BUT DOES NOT GO DOWN.
So I took the door off and the looked at the harness, and lo and behold, the green/black and the blue/yellow wires were bad. Soldered the green wire back together, and reconnected the blue/yellow wire. That did nothing.
Back-probed I believe the blue/red wire and gave it ground. SUCCESS. The window actually goes down! But then the fuse keeps blowing. I've got an extra good motor and a regulator outside of the door, and it does the same thing, so I know it's not binding linkage.
YOU MAY STOP READING HERE AND SKIP THE FOLLOW PORTION. (Because I don't know if it's relevant or makes sense or something.)

Here's the interesting part. If the temporary ground is connected, and I go up, the fuse blows. If I disconnect the ground, I can go up as much as I want with no problem. And if I want to go down, I reconnect the ground.
I think, and I could be wrong, that if with ground connected, I first go up, it'd be okay. But if I go the opposite direction, down, it'll blow. Or if I first go down, it'd be okay, but if I then go up, it'll blow. I'm not sure if I'm remember this correctly, but this could be the case. Maybe some magnetic reverse polarity something something magic going on? I have no idea what I'm doing.

Any chance there's something else on that circuit that shouldn't be? Maybe a 2nd 12V power source for a nav unit or something?
Are you sure the fuse is the right amperage for that circuit? Maybe somebody out a 5A in there because that's all they had, but it should take a 10A?

Re: Window motor fuse keeps blowing. No Ground. Damaged door harness wires.
Fuse is correct. Now I would love to put a 50 amp fuse on there and set the entire car on fire. That would be awesome. There are wires for a stereo system, the kind deaf people like to put in the trunk in order to feel the music since they were not blessed with the ability to hear, but I doubt that's interfered with the window circuit at all. I'm sure it's something much simpler.

Which is ground? How can we narrow down where the possible problem is, where ground is disconnected? If all other windows work well, and this window, the front passenger window, goes up but does not go down, going down only when jumped to ground, where might the break in the ground line be?
