Awhile back I had my headliner replaced and really didn't pay attention if my interior lights worked after the repairs until weeks later. They all come on when switched on. The map lights also work when switched on. I'm kinda puzzled why they don't work anymore. Checked the switches on the front doors and they work. Really don't think the trunk switch has anything to do with my problem. I'm thinking it may be some type of timer or relay that's faulty. I really don't know need help.
