Hi all, I have an 06 F250 Super Duty crew cab. I have a condition where the rear passenger window wont roll down. I have tested the motor both directions (bypassed switches and jumped straight to a power source) and the motor is good. I have lowered the window (with outside power source) reconnected the switches and both master switch and window switch will roll the window up.

My question is does anyone have a schematic. Does anyone have a thought how/why both switches wont roll down the window.

Thanks in advance

Mike

 

Most likely the master switch has a dirty contact for the RR window, yet there's also a chance the RR is bad although less likely due to less use. Attached is the schematic so you can track down which switch is not working correctly.

 

I took that master switch apart yesterday but it was different than what I have worked on in the past. How do the switch covers come off? I didnt want to break any plastic parts.

I got it out of the door and then separated the base from the top. But the board is still attached and at that point I was like, let's not get over eager.

So it turns out it was a dirty contactor. I disassembled the master switch and found a build up of "crud" (kinda semi liquid.) I used a q-tip to get in there and once it was clean I took a flat head screw driver (very small) and made sure it was smooth and no build up.

I took a few pictures, to help out the next guy. There is a good video on YouTube of an 05 which isnt the same exact process but fairly similar.


Its worth noting, I did "break" 2 of the 4 switches. There are four tabs and one broke on those two switches. Not sure I could have done anything different and in the end it didnt effect reinstall or performance.

Thanks for the heads up and the pictures.

 

Sorry I didn't get back sooner to answer your questions, but it looks like you figured it out and got the window working again...for free!

 

And we all like free!

Thanks guys, hope it helps someone else.
