Recall the driver door was swapped out, so the exterior handle and lock were switched over from the old door. Possible fault in/damage to the door harness during changeover?

The driver door switch 3/100 performs one function, closing the (normally open) switch when the door is opened.

This function also turns on the kick plate light and the door warning light , and these both function correctly. The same grounding also pulls a ground on the 2/76 lock controller telling it the door has been opened which should toggle the dome light on, but’s that function does not work, once the ignition has been brought out of cold state. It does work when the car is in the cold state.

Crazy.

I have confirmed the correct function of the BR ignition trigger wire to the 2/76 controller as an obvious culprit.

I love the smell of an electric problem in the morning.....smells like,......victory.

Two more things to note on this unresolved one

1 current drain problem on fuse 11A/6 about 200 mA....wouldn’t you know it. Fuse 11A/6 Also feeds the 2/76 lock controller

2 Abby reports the car won’t let her lock door while driving unless she toggles the done light to the ON position. If she uses the door lock button inside, the door locks quick cycle closed-open

If she activated the dome light once, that switch works.after returning it to the off position, the lock button still works

:lol:

I’ve been inspired by another thread

I think one of the door lock actuators is sticking and keeping the lock controller active , which causes both current drain and lights on
