Default Back Window Wont Go Down


I recently purchased my Lexus. Its a GS 350. Year 2008. Its fully loaded and today when I went to roll down all the windows that back passenger side window would not go down. I checked the child lock on the door. I checked the window lock. I checked the window control on the actual door in case it was the button on my door that was the issue. I do not know what the problem could be or how to fix it. Also how much a fix like this might cost me.

If neither door switch works it is probably the window motor itself in the door. Sorry I don't know the cost, but I would probably start by searching EBay for a used one. Dealer cost for new will be outrageous.

Could also be the MPX module.

I'm new to the Forums, so hello. I had the same problem on the same door but on a 3rd Series LS430. If there is no sound then suspect the motor.
I got an excellent window mechanism c/w motor from eBay for 20. At that kind of price it is worth replacing the whole thing. Dealer quoted 1027 to do the job.

The replacement itself is easy. The most fiddly and time consuming part was removing the door panel.

Good luck AlRose
