Hey all, I have a 2001 LS430 and the driver window will not roll up or down at times and it will stick open. I've used the search function and can find that my issue is in regards to the regulator, or the motor. My question is if I can replace either of the parts with a motor/regulator from one of the rear windows? It is my DD with 190k hard miles as the previous user did not take care of the vehicle so I am trying to fix it up on the cheap. Any thoughts?

The window regulators are not interchangeable.Pull the door panel off and see if the motor works.If it does order a regulator.

When mine does that, I just wait a few minutes and hit the switch again...then the window goes up a little bit...wait a few more minutes...hit switch again.

That is what I am currently doing, but with the rain I'm getting in Northern CA right now it's not fun waiting lol

Any other thoughts to fix this on the cheap??

my passenger window does this. Is it a symptom of the motor or regulator?

Thanks!

I'm going to try this option:

I have the same problem with the Rear o/s passenger door. I replaced the Regulator and motor for $30.

I have proved the motor/regulator works, but when I hit the button the window winds all the way up and then down whereupon it will not respond to any commands. Fiddling with the wiring harness sometimes kicks in but cannot be relied upon. I have tried the switch from the opposite door but same thing happens, so it is not the switch. None of the limit switch re-set tricks work. At the moment I have got the window up and have resisted temptation to 'try it again.
I now suspect the Rear Door Control Module. I have ordered one from eBay ($30) Will try to let the Forums know what happens.

My driver window does this intermittantly, especially in the sun. I've found I can expidite the wait time a little by pulling the glass towards me and holding for a few seconds and releasing and hitting the switch again. - Seems to be some drag from the window rubbers or something. I've tried silicone spray, but that didn't help

Aus430. Thanks so much for your response. I also have tried all you describe. I now suspect a previous owner has had the door panel off for some reason and has failed to put it back with the seals in the correct place. It definitely drags going down but is fine on the up sequence. AlRose

Before all that you may want to try using some lithium grease on the track; my understanding is most window motors burn out from a lack of it...so trying that may solve your problem, and if it doesn't what would it hurt? I actually have this problem with my FR window, when I get a chance I'll try and post my results.

My driver window at times will go up a few inches and then go unresponsive. Wait a minute and it goes up a little higher. Seems to do it more often when I hit the switch all the way up or down to trigger the auto open/close feature. Does this sound like the motor or the regulator? Or will I not know until I get the panel off?

Lexus dealer just gave me a $99 quote to diagnose and then $1100 to replace both motor and regulator. Needless to say I’m not interested.

TIA for any help!

I had the same problem I sprayed 303 on the inside and outside window seal and now it rolled down fine but it’s gonna leave a greasy residue on the your window tho

My passenger window did that, replacing the motor with one from Amazon did the trick
