I have a 1991 F250 7.3 w AT and 4whld. I just bought the truck as a project, bc it had several small issues... Passenger side power window being one.
I have a reman motor, and two different switches and wireing blocks. The problem is it will always move downward but only sometimes will the motor turn when the "up" side of the switch is pressed....

Does anyone know what the wires are supposed to be (hot, ground) in "up" "down" and neutral position?

 

Ok I found that's it's a ground issue (the red and black wire) now... Where is it grounded at?
Also my left rear blinker/brake light is not working and seems to be a ground issue.
Related?

Thanks for any help
