Very good detail in the photos, thank you, a big help. I have a rear window that opens every time I start the car and the master at the drivers door doesn't work for that window. I will disassemble as described and post the results. Thanks.

I just bought a 2002 rx300 the other day. Today my driver side window did some really strange behavior similar to what you're describing. When I pushed the window down button it went both up and down a few times. I let it calm down and it returned to normal.

Did anyone else have luck with cleaning the device? A can of compressed air and 15 minutes sounds a lot cheaper than the other solutions.

I fully disassembled and cleaned the part this weekend to no avail. I believe it is the failing relay on the board. Not the best at soldering so it looks like this will be an ebay purchase.

Before I do, does anyone know if there are any other p/n's that are a direct swap out for this module? I know many toyota parts fit on the lexus.

Cleaning the control to the automatic window worked for me I wish I had something else I could add. Good luck to you

The large relay on the circuit board controls the window's direction. Mine was acting horribly until I replaced that relay. It's out there... Just google the numbers on it.

Picked up the part from a person who was parting out their rx300. Problem solved.

Dont mean to necro this thread, but the actual rocker switch broke off on my master panel. The whit pegs still allow the window to work. So I just need to buy a used switch and swap out the rocker portion?
