Alright, I've done some research and tried to read some wiring diagrams, but still unclear as to what the problem is. It started with not being able to roll down the passenger side window. I swapped the switch on that side and nothing. Swapped motors and it was working, but only from the passenger switch. However after awhile it stopped working completely again. Plugged in the old motor again and held it it my hand. Now both switches can spin it when I press "up" but can't spin it when I hold "down". I tested for power with a test light and when I hold "down" both wires coming off the motor are lighting up. Bad ground? Driver side switch acting up? Need some help.
