possible short?

Whazzup forum. >- I am not new to the site, but new to starting a topic. Okay I'm just new. Anyhow, I have seen alot of helpful tips for the rear window problem many have been having. After reviewing several of them I finally decided to try and fix mine. No can do. I bypassed that connection that doesn't allow you to use the rear window when the tailgate is down. Still no up down rear window action. From there I traced the wiring to a gray male female connection below the rear window inside the tailgate. I disconnected that, and ran a jumper from the battery to the plug going to the motor. SUCCESS! /emoticons/[email protected] 2x" width="20" height="20" /> Window goes up window goes down. However when I reconnect the two,turn the key,and press my rear window button, nothing happens. FAILURE! I am getting 12v at the gray plug coming from the bypassed connection. But when I connect the two gray plugs, have my gal press the button on the dash, and check voltage at the gray plug I get almost 1volt basically nothing. Just a faint noise coming from the rear window motor. Possible short? I don't know. Any troubleshooters out there? Trying to cover everything, sorry about the long post. 1995 Bronco XLT 5.0L 305

If the same thing happens from the tailgate switch, it is probably the ground return line. That goes all the way back to your dash mounted switch and grounds under the dash. Attached is a diagram of the circuit. there are two fuses involved, one for the driver switch and one for the tail gate switch. If you probe the Black with White stripe wire that should be hot at all times. The Purple with light blue stripe should be hot when the driver switch is pressed in the down direction and the key is in run or accessory. When pressing down the Purple with light green stripe is the ground return path. When you press up the wires swap functions. As you can see, there are several connectors involved and a failure can exist at any one of them plus the wires tend to break where the flex between the tail gate and left quarter panel.

Good luck,

Thanks Seabronc. This at least gives me another idea where to start looking.
