Problem with courtesy lights

[motornut]

the wire is white and comes threw with a rubber groment above and left of the e brake pedal(same place on ther side)
unsrew the switch in the jamb pull it out and check for crud
two wires one for the light and one for the buzzer
in mine there is a wire that connects the dome to the under dash lights
it was by the fuse box(all white wires)
in mine the wire ran across just under the lip of the dash to a light by the hump
this might help find your wires/probs
