Has anybody encountered their interior lights all of a sudden not working when unlocking or opening any of the doors. Before anyone says anything, Yes I have checked to make sure the headlight switch is not in a position that would make them stay off.

Right now I have disconnected the batteries to reset the control units and have a battery charger on the batteries to ensure they are at full voltage.

Has anyone else encountered this and what was the fix? The dome lights work if you manually activate them by the lenses but with doors open or when unlocking with the remote they do not.


Thanks in advance guys for any info,

 

Man.....almost has to be a module. I think it is run thru the instrument cluster too. here's all the wiring diagrams I could find.

 

Check this connector too.....C201 IIRC, it is under the driver's side A-pillar trim.

Here's the pinout too.

C201 - WHITE (HEADLINER SIDE) CAV CIRCUIT
1 D25 20WT/VT (PREMIUM)
2 Z13 20BK/WT (PREMIUM)
3 L50 20WT/TN
4 Z350 20BK/TN
5 A919 20RD (PREMIUM)
6 F21 20PK/DG (PREMIUM)
7 L14 20WT/TN
8 Z964 20BK

Thanks Man!

I am suspicious of a C/M as well but hopefully resetting the C/M's will fix it (not holding my breath however).

Looking at the diagrams closer it looks like the IP C/M provides power to the lights. The lights do work when operated manually so that tells me the power source is OK but also tells me that the multiplex system for the illumination control that powers the drivers is not working right....next will be some fancy pinout testing if it doesn't work when I hook the batteries up tomorrow.
