Last week the power rear window stopped working. It turned out that the wires and the terminal on my battery were corroded to hell, and I wasn't getting any (-) signal to it. I replaced the terminals and the switch started working the window again. With the switch to the full down position the window was still exposed about 1.25" over the tailgate. I pushed the window down about .25" and now the window isn't going up or down whatsoever. I unplugged the harness and tried feeding the power directly to the motor, but I'm not getting anything. What have I done, and what can I do to fix this problem?
