My dome and interior courtesy lights stay on all the time. I've tried to check everything I can think of but no luck yet. Am I overlooking something easy or am I going to have to go to an electrical specialist? Any ideas?

Hello,

There is a courtesy lamp relay that sounds like it is sticking that needs to be checked. Here is a guide to help us with the relay test and the location including the courtesy light wiring diagrams so you can see how the system works.

Check out the diagrams (Below). Please let us know what happens.
