Power window issue
03 F250. Passenger window is stuck up. When I have the door panel off, I can feel the motor trying to move up. Won't go down at all. When I connect test light to the plug, it lights up correctly for both up and down. Thought maybe it was the motor so I got a new one but it only tries to go one way. It's like the switch isn't sending the signal for the window to go down even though the plug appears to be getting the correct signal.
I took apart the driver's side switch and nothing looks crimped, bent, etc. From some reading, it sounds like possibly the regulator is bad, does that somehow send a signal back to the switch? Is there a relay or something that could be bad?
I find it odd that test light seems to work but when connected to a motor, it doesn't.
Thanks - Bryan
