Tail and dash lights dont work on 1990 gmc truck. Changed the fuse. What else could it be?

Usually, open circuit conditions are caused most commonly by:
- A wiring harness connector has become "unplugged," or
- Corrosion has built up on the metallic connector pins INSIDE a connector or any type of connection,
- A conductor [wire] has been broken or cut.
There are probably a few more possible causes which I can't recall, but these are the most common.

Why would a 1990 Nissan 200SX parking lights and tail lights stay on when you turn off the ignition?
Probably the rubber bumper/stopper which depresses the brake switch is gone/disintegrated. Check beneath the brake pad for broken pieces. Without this piece in place, the switch is always closed and therefore powered to light up the lights.
1990 ford econoline 250 van has no instrument lights. All other dash lights work and I put a new light control in and still no instr. lights.?
Check to be sure that the headlight switch knob, has not been rotated to turn off the dash lights. This knob acts as a dimmer switch, when rotated. This feature of the switch works on a rheostat. This can also be broken or corroded. If all of this checks out there is also a fuse for the dash lights. check the fuse ,if not the fuse replace light switch
Why might the dash and tail lights not work on a 1989 Buick Century?
Answerit could be because one of your tail lights, brake lights, reverse lights, etc. the dash light goes off to let you know this. there is nothing wrong with the dash, probably. then again i have also seen minor electrical parts fried that cost an immense amount of mula. try the lights new answeri hit a deer once and that same thing happenned to my '88 century. I ended up replacing a fuse in the dashboard fusebox that, in the manual that came with the car (if i remember correctly) did not directly correspond to either the dash lights or rear lights. only after checking ALL the fuses and after the replacement of this supposedly unrelated, yet obviously blown fuse, they worked.My wife decided to jump start another vehicle during our ice storm and burned the contacts in the light switch.. which was the contact to bridge the dash/taillampsNew answer:I had this same problem with my 1990 Century. All my lights worked (except dash/tail) and my fuses were good. Replacing the head light switch took care of the problem. I hope that helps
