Courtesy lights do not go on at all. Map light works when I manually turn it on with the switch on the mirror. Checked the fuses every-thing is good, checked relay and checked the door locks. What an I missing?

Hello,

The interior lights are controlled by the BCM. I would make sure the fuse has power for the system and then check the ground and switch operation. If everything checks out it sounds like the BCM is bad and needs to be replaced. Here is a wiring diagrams for he interior lights and the BCM location along with a guide to help you do some testing.

The BCM will need to be programmed by a shop if found to be bad.

Check out the diagrams (below).

Please let us know what you find. We are interested to see what it is.

Cheers, Ken
