I know this has been daicussed here before but I have some interesting symptoms to do with my drivers side window not going up in my 93 Z28.

It's currently all the way down. When I depress the rocker switch in the up direction nothing happens. If I press the down direction I can hear a faint click sound, possibly the travel limiter. Urging the motor out since the window is already down? The passenger side window works fine from the drivers side switch panel as well.

I've already replaced the motor with a dorman unit from autozone which did nothing for my problem. If I wiggle the wires, force the switch to female plug together more, hit the door, attempt to pull up on the glass all while depressing the switch I get no change. The wires into the female plug do seem loose to me but all six (3 drivers side and 3 passenger side) all appear somewhat loose. The rocker switch itself is out of a 98 Camaro and appear to be I good shape. Any help would be greatly appreciated.

Just one last update here, using the diagram from shbox: http://shbox.com/1/window_motor_switches.jpg I'm using a multimeter and I'm plugging the black lead off of it into the black wire in the connector(A) I'm then touching the red lead of the multimeter across the other terminals and getting these voltages: B-5.4v, C-5.7v, D-11.2, E-11.2v, F-12.4v Are those normal readings? If not where should I now be looking? Also is there a way I can "jump" the motor to bring the glass back up so I can at least drive around?

Please ignore that last update, I realized I was using the multimeter wrong. This afternoon I connected the multimeter to a ground then touched across all six terminals on the drivers side power window female connection http://shbox.com/1/window_motor_switches.jpg

Across terminals D, E, and F I got 12v but across terminals A,B,C I got random numbers constantly changing.

I also put the probe into the plug going into the window motor itself, when depressed in the down direction I got 12v on the Brown wire but nothing on the dark blue wire regardless of switch position.

I also tried just unplugging the express down module under the dash but that just stopped the windows from working all together. I should also point out with the window motor out of the car the down direction works fine but not the up direction.

Sorry again for all the posts but I'm really stuck trying to figure this out.
