Id post this in the 4.6 tech specifics, but its not specific to the v8s. I figured id get more traffic and better help here. Anyway, ive looked around and found some good threads on how to test what and to figure out what part could be bad. After testing everything, im still stumped. My passenger window switch will only work going down. It wont lift the window back up. The motor clicks when you hit the down, but doesn't click on the up button. The motor is brand new, ive tested it to make sure it works both directions with a jumper. I cleaned all the switches thoroughly and still no different. I used a multimeter on the switches and motor and all is well. Now... my drivers window wont make the window go up OR down. The mirror moving switch doesnt work for the passenger side, but when you select the drivers side, it does. The drivers side window does work too. What could this be, and how could i trace this down??? Thanks!
