Power windows
My dad has an 87 F-250 4x4 with power door locks and windows. The passenger side window will roll down but will not roll back up using the switch on the passenger door. It will roll up and down using the switch on the drivers side.
I have taken the switch apart, checked the contacts, there is power going to the motor when you put the switch in the up position but it won't go up and there is no motor hum.
I have no idea how these are wired. Is it possible for the motor to be bad, yet still work from the drivers side? I didn't have a lot of time to check it out and dad is 250 miles away.
Any ideas would be great to have before I go visit again.
Thanks
Kelly

Works from drivers side but not pass. and there is power at the motor from pass side switch? Puzzling!!! You did probe at the motor after the connection - correct. If you didn't there might be a break in the wire or the switch still could be bad by not giving enough amperage to the motor by having a poor contact.

I believe the power goes first to the drivers side. No direct power to the passenger side. Three wires go from the drivers side to the passenger side. The door locks are a seperate set of wires. I believe the windows change direction by the switch changing which wire is grounded. So possibly there is a bad ground, this is only a guess. I'm sure Franklin in the electrical forum could tell better.

Not having a complete schematic for that wiring does not help. There are several wires going to the passenger side switch but only 2 go to the motor. Using a test light, I put the switch in the up position and one wire is hot, put it in the down position and the other wire is hot, which is how it should be, yet the window will not go down. I was testing the wires after the connector. Wires go from switch to a connector then to the motor.
I didn't have enough time to pull the motor right out and could not see if there were other wires going someplace else to the motor. The passenger door lock also didn't work but did from the drivers side. That was an easy fix in the switch it's self, contacts were bent a little. The truck only has 63,000 on it and still basically looks new.
I remember dad said the drivers side window motor went out and he had someone replace it. Now I have to wonder if they did something wrong on the drivers side that made the passenger side not work.....hmmmmm!
Thanks for the ideas.
