Hello, the dome light in my '97 Z71 all of a sudden will only be very dim if it comes on. I also noticed the cargo light does not come on but the third brake light still works. I did install an aftermarket LED brake light and put in an LED bulb in the dome light. The control switch for the lights is only a few years old so I don't believe that is the problem. Does anyone have an idea why my lights are not working properly?
