Hello CL members.. I've been poking around on here for a few months now and seen alot of great builds and threads. I hop I can get some of your help.

Recently my driver's side window would intermittently roll up and down at certain intervals. Usually the buttons would be backlit to show they are operational but now it seems I have no lights and or power to just the driver and passenger window switch from the driver door. The lock button and side view mirror control still works. I tried changing out the entire switch assembly but still had the same problem? Is there a computer module I need to replace that controls the whole unit? Any ideas? TIA for the hell guys.

Welcome to Club Lexus.

Check your wiring harness that passes from the chassis into the door near the door hinge. Frayed/chaffed/broken wires are frequently the cause of these type of problems.

btw, there are numerous threads here dealing with this type problem; try searching a bit more.
