Odd power window issue

Recently my power windows stopped working...sort of. Here's what I mean: If the drivers door is closed none of the windows will go down. However, if I open the drivers door halfway or all the way I can roll up/down all the windows. If the windows are down and the drivers door is closed I can, almost always, roll up the drivers window, however the other windows in the truck will usually not roll up. Open the door halfway and up they go.

A couple of other things I have noticed. When I press the down button for the drivers door window, with the door closed, I can hear the relay, under the dash, kick on and the window will move about a millimeter down then stop. Additionally, the courtesy light on the drivers door comes on while the door is closed. I haven't checked if the other courtesy lights come on at the same time.

Hopefully my explanation is understandable. I would love to solve this issue. Getting tired of opening the door to roll down the windows. Plus when there's a fly in the truck and I'm driving I can't get it out.

Sounds like the motors are going South on you. Very common issue. They have thermistors in the power control circuit that go bad. There are "fixes" that can be done but a new motor R&R is much less hassle, just more expensive. That said, I don't think that the new motors are all that spendy.

My guess is the wiring harness to the driver's door. Some of the wires are probably broken and separate when the door is closed . When you open the door the wires push back together and complete the circuit. Same with the courtesy light, they operate via a ground switch and the wire might be abraded and grounding out.

I have had this happen on numerous vehicles over the years.

Thanks for that video link. It had some good information in it. I won't be able to tear into the problem until next week. I'll update with results.

Wow that's a great video Arizona97. My truck needs speakers and I am dreading getting the door panels off without breaking anything and I don't trust the install shops to do it right.
