Window controls trouble shooting advice (1 Viewer)

[chipsterguy]

I am baselining my new to me 2015 LX570. One of the items not working properly is the passenger rear window controls. The window operates just fine from the controls at the door. However, it does not operate from the driver seat control. Other windows seem to operate fine from the driver seat door controls. Any recommendations on what I should check first? Thanks in advance...

I'm pretty sure the drivers door switch controls the other doors' motors/switches via LIN bus. Other than verifying continuity on the LIN data wire (green on 2013 I think) between swich modules, I don't think there's much more a home mechanic can troubleshoot. Unless this mechanic happens to be an electrical engineer with test equipment

Edit: you may be able to troubleshoot with Techstream...
