id still check the rheostat (dimmer thingy) mine is apoparently broken too, the lights are on about halfway, and when you turn it all the way the domes come on. another way to check would be to bypass the rheostat and see if the lights come on

here's instrument lites trouble shoot 101:

check the fuse. if bad, replace fuse. if not,

check voltage after rheostat. if 0volts, bad rheostat / rheostat connections. if 12volts,

check voltage at dash connector. if 0 volts, bad wiring from rheostat to dash. if 12 volts, bad bulbs or bad internal dash wiring.


if you want, i got some shematic diagrams, just tell me what year truck you got.
