Hopefully others have ideas.
well the work didnt involve taking off any of the battery cables or removing the battery.

Assuming it is the switch and not a wire or some other issue, remove the existing piece and replace with this (for Japanese VIN) ... ~$70.

Problem could be the rear switch/module too.
The MPX1 wire at rear door switch/module is expecting a data/command to open window remotely using key or driver door switch.
Because of complexity is only reason suggesting the initializing procedure to rule that out first in case it was lost and visual inspection of plug connections.

PS- switch/ module is all one piece.

Where on the door is this module or switch? I already tried the key and tried to initialize the window and that didn’t do anything either; also the window will go up and down at the switch on the door itself but will not auto up or auto down.

I might end up getting this but how hard is it to Get the old
one out and put the new one in? Also; how do I know it’s not a wire(s) somewhere between the module/switch and the window motor to which the wires for the controls run to?(im assuming)? See I just don’t want to end up throwing money at it only to find out it’s a totally different issue somewhere

Hi Matts, Techstream or a high end scanner can be used to see if the rear switch is responding to remote commands for Up & Down.
Pulling out the switch is easy for inspection and replacement.

Front switch at 0.50s in video.

That is why I asked in post #3, if the shop diagnosed that the master window switch was bad, so you wouldn't be throwing parts at it without knowing exactly what is wrong.

matts you have stated the rear seats are not used, and also that the window can be controlled from the rear controller.

Why waste time and money on a function that you do not use. (if the rear seat is used, they can operate the window with the rear control)

Highway robbery! IMHO
They swing for the home run $$$ on these parts considering it's only a 10 minute job to pull the switch out.
