Dome Light Wiring Help!

[hbryant123]

Today i just bought my first full size truck, a 1990 chevy silverado, regular cab long bed! The dome light, center part and the side lights that have the black switches do not work, the courtesy lights on the floor do not work either.

With my test light i determined the courtesy lights just need bulbs, the bulbs looked good but do not work but the sockets are getting power.

The small click lights on the dome do not work and the center part does not light up, i checked the the socket and it does not appear to be getting power im assuming one side would get 12 volts.

Im looking advice for what to check next, would be nice to be able to see in the dark! Thanks in advance!
