Default Electrical issue

Hi,
I need help figuring out the following. The main window control controls all windows except for the drivers side window. No other window control by any other door works. My mirrors do not move by the joystick. Neither of the front seats move. I 100% checked all the fuses in the heel boards. I doubt that all these items stopped working at the same time so they must be related somehow.
Any suggestions on how I should continue sorting this out would be appreciated.
Jomo

I had a problem with the driver door control not moving the driver window

Found on the control connector lock bar loose letting the pins migrate away

You can test the strength of the of the window motor with a battery charger or regular battery with jumper cables as the 2 heavy wires at the front door panel opening , in the end as fully together would have to hold up button for a few seconds as window glass up , this clocks the controller

You could try a hard reset. Disconnect the battery and join the wires together for 30secs or so. This will sometimes fix odd problems with the window control, not sure for the seats. Or it might be the 308 I am thinking of!

Certainly, an easier / least intrusive first try

On the Hard Reset , the longer the better , like overnight

You can join the 2 battery cables together with a heavy car start jumper cable , battery cables removed from battery post , important to not short out battery , place a shop towel over battery to prevent contacting battery post

I’m still not sure where this hard reset rumor started from….

Has there ever been a post where this worked? Where it solved anything?

It works on the X308 so why not the X300

I've had results on the X300 security system , so why not try for the SLCM , BPM related systems

Free , easy try so why not if it doesn't hurt anything , only may be a misleading task in the process of problem solving if you don't set all your hopes on hard reset being the solution

I tried all methods of hard resets and unfortunately it didn't help.
I'm going to look at the wiring schematics to see what I can find. Does the body control unit have anything to do with the windows?
Thanks,
Jomo

Body Control Module ( BPM ) ...........no . Besides BPM is buried fwd of glove compartment

But fuses off top of head 1 fuse powers both front windows

See page 22 for heelboard area

The only thing that the BPM does with the windows is the "All Close" function, from my reading of the schematic.
