Default Driver's Window won't go down. New motor assembly doesn't work.

My Driver's window had a history of being super slow. Recently it decided to kick the bucket and now will not go down at all. All of my other windows work fine. Here are the things I have tried
  • Disconnected the switch. Cleaned with Electric Parts Cleaner and Compressed Air
  • "Hot Wired" the old motor using the battery. (This did not work so I figured the motor was shot)
  • Purchased New Motor and Regulator Assembly

I tested out the new assembly before installing, I felt the Regulator budge a bit but that was it. Sadly nothing seems to work. My window is currently taped in place, it's raining, and I have work tomorrow

It tries for a brief second once first plugged in. After that initial budge there is no sign of movement

Take the door panel off and check the connectors on the control panel that was my problem this week.

I haven't even put the new assembly inside the door because it won't work outside the door.

I took apart the entire control panel and cleaned the switches with electronic parts cleaner and compressed air. No such luck

Did you take the tape off when you tested it? Because it sounds like the window itself is jammed or the rail below it isn't guiding the support for the window. See if you can actuate the window without the motor.

If i understand correctly he tried that with the new regulator not yet installed and still didn't work. Same symptoms.
Is that correct OPer?

If so, and if no broken door jam wires, i'd start thinking about changing the window switch module. They go bad....a lot.
Can get a new one on fleabay for around $40.

Yes this is correct. I considered buying a new switch module but everything else on the switch works. Even the light for the unworking window

Stupid question but inside theres the little rubber strip that goes along the bottom of the window check to see if that squished itself inside the window. Mine randomly did this and wouldnt open at all. Stupid i know but worth a check.

Those LED lights work independently of the actual up/down switches.
For your issue, it means nothing if the LEDs work.

I had an issue where the driver's side switch wouldn't control the pass. window.
My original 290k+ mile front driver's switch module has long been resting in a land fill somewhere.

Since the new regulator still exhibits the same symptoms, its typically:
-broken wire(s) in the cable at the door jam
-bad or corroded connector at the switch module
-bad switch module

There's a Utube video on how to inspect/repair the typical fault these switch modules have, namely cold solder joints develop on the internal printed circuit board.
Caution, it a mild PITA to disassembly the switch module and need good soldering skills.
Good Luck!
