My cabin light (the one above the rear view mirror) has suddenly stopped dimming when closing the door. It just stays on now. Fortunately I can turn it off manually so the battery doesn't drain. I'm guessing the dimming relay or the micro switch has failed. Anybody been their and has a fix? TIA

 

This has been discussed before, this is one of them. I hope it helps.

"Dome light" is a good search.

 

All is well again......the rear hatch was not shut properly........doe!
