I'm trying to get my dome lighting to work, (used to work but doesn't now) so I take off the dome mount and there's nothing but a couple screw holes on the roof that feed into a small case where the wiring is. ok stupid question time: Is the mounting screw what transfers the electric? I don't see anywhere on the dome mount that offers a place to connect the wiring.... ok second stupid question: how to I go about testing to see if the wires are working?
Also- I noticed my driver side door switch chime only works intermittently.
Thanks-
