Problem with front passenger window on my 2002 RX 300
 

The window seems to have a mind of its own. You try to raise it and it might go down and the other way around.Now my wife lowered it and it would not come up. I started to beat on the door and holding the switch and it finally went up.It acks this way from both driver and passenger switch. I took the RX 300 to a non Lexus auto service and he feels it is the master window switch/module. This is $800.00 just for the part at my Lexus dealer. I like to know is there any used ones out there?

Ebay sells much cheaper.

Did not see any on Ebay.

thier are four on ebay
1 has a part #270811315217 $227.

I will have another look thanks.

Yes there is some on Ebay. When I searched the first time I did not have the part #. I put in 2002 Lexus RX 300 master window switch/module.Thanks again.

Any update with faulty window?
 

My front passenger window is doing the same thing. I replaced the master switch (front, driver's side) but no luck.

Have you resolved your issue? If so, what worked?

I ended up replacing the front passenger window switch to fix the issue. I bought a used one Ebay.
