No dash or dome lights

[AlainRenteria10]

1989 Chevy C1500. No dash/dome lights. Gauges work. Dad said they stopped working after an accident on the drivers side cab corner. Any clues on how I should begin to approach this problem? Any fuses or wiring schematics that can help. Thanks

Do your vanity mirror lights work?

Truck doesn't have them. I'll look at grounds this weekend. Really sucks not having them at night, plus I want to do the cluster LED swap. Do you have any idea where I can get wiring diagrams?

The factory GM service manuals should have them. Physical copies are expensive, like $100+. However you can download a PDF copy for your '89 from this thread:

Big thanks to @hatzie for posting those.
