I could see through the door gaps that when my passenger door was open, my driver’s door lights were lit. That’s not supposed to happen, the door lights should operate independently. After reviewing the wiring schematics, I traced the problem to a bad diode.

Hey, is there something wrong with my steering column?
The door lights now work correctly.
