Driver's side door & window control (1 Viewer)

[rcpalmer78]

Ever since my wife took her truck (2010 LX 570) to the carwash about a month ago the driver's side door lock and window controls are malfunctioning. All other controls on the other doors function normally, so no problem with any actuators. The driver's side will roll down its own window, but that's it. Even more aggravating is that the rear hatch will not unlock unless you have the key on you. I've searched the forum and haven't found a similar complaint. For troubleshooting I've pulled about 15 possible fuses (hood and driver's side panels). I did find one of the proper ones. All that did was stop me from being able to roll down that window from that control. I also swapped the door control out from my 2016 TLC- an exact match btw - still able to roll down driver's window and nothing else. No luck changing the vehicle settings in the nav either. Doesn't matter which key I have in the truck. Out of ideas except for going to the dealership. Thoughts?

Appreciatively,
RCP

Maybe something in here might help?

Sounds like you tried all the obvious things, but I've got no clue!

Greatly appreciative. Will give it a look.

Sometimes I feel like as a group we are bad about follow up. I know I am! As an update, I took it to the lexus dealer. They tried all the things I tried. Wasn't the switch or the ECU. They then pulled apart multiple modules and reconnected them. That solved the problem. It's been a few months now and no issues. I'm not sure if that will help anybody down the road, but that's what provided the fix - just a loose connection somewhere.

Cheers,
