2002 Ford F150 Driver’s Window Goes Down, Does Not Go Up

This 2002 Ford F150 came in with the complaint that the driver’s window goes down but will not come back up. The driver’s door uses a one touch auto down feature that makes it a little difficult to test but this one was even more difficult due to the fact that the wiring diagrams did not match the truck. I had jumped the wiring at the window motor the evening before so the customer could drive home and bring it back when he had a ride.

The first thing I had to do in order to remove the door panel was the grasp the left edge trim panel and pull it from the door.

Once it was removed I had access to the hidden screw and I removed it.

Next I removed the switch panel by lifting up on the forward edge and sliding the assembly forward towards the door jamb.

After unhooking the harness connectors I grabbed the upper edge of the door handle bezel and pulled the forward edge away from the door.

With the front clip released I slid the bezel forward to release the rear edge.

The next step was to remove the screw that was behind the bezel

After that I grabbed the pull handle and lifted the door panel up and off of its hook retainers.

With the door panel away from the door I leaned it out and reached down and removed the courtesy light from the panel. Just twist and pull.

I removed the four screws that held the speaker in place.

Depressed the latch and pulled the harness connector from the speaker.

I started pulling the vapor barrier loose being careful not to damage it.

I then taped it up and out of the way so that I could work unencumbered.

After physically identifying the wires, I determined a test sequence. I did not take pictures of the testing until after I had put the door back together. So I had to pull the switch back loose to show testing. Testing was done with a fused jumper wire and a test light.First I checked the wires to see which one had power on it with the key on. It turned out to be a green wire at position 4 although the diagram shows that it should be a light blue/black wire.

Next I checked the brown/white wire, position 8 (white/black according to the diagram) as I had traced this one back to the motor when the door panel was off. It had power on it with the switch in the up position. I next connected my test light to a power source and checked to make sure it had a ground in the down position. It did.

I then by checking the diagram and by finding which wire position I need to test I found that the red/yellow wire, position 7 (tan/light blue according to diagram) was the next to test. I tested and found power in the down position but no ground signal in the up position. This was the cause of the complaint. A faulty switch.

To further prove my diagnosis I pushed the switch in the up position and jumped terminals 7 & 4 together with a fused jumper wire and the window went up. 100% power window switch fault.

I installed a new switch and called this one done.

  1. Sparky, The right door window will go down, but not up. I replaced the motor, it went down and not up. Same result if I use the left side switch. I haven’t used the test light yet. But don’t know how both can go bad at the same time. I am puzzled. Kind Regards, Mike

  3. I have the same problem with my driver side window, put it down, wont go up, seems that relay #1 is clicking, looked at the fuse diagram but could not determine which fuse or relay is for the windows? My passenger window works fine. Any help would be appreciated.
    I understand I may be posting inappropriately but having same issue
