I just installed two LED strips under the dash, and linked my dome lights to the map lights (as well as changing out the bulbs to LEDs) the other day and it all dimmed perfectly for about a week. Today I noticed that it all stays on without turning off. The car can be off and locked and they still stay on. The lights were all tapped to the dome light wiring (hence they all dimmed). Anyone have an idea what could be the problem? I'm going to trace the wires and see if anything got grounded to something other than the dome ground. But if anyone has any insight please let me know.
