Cab lights quit workin on my 97 All other running lights work, got power and ground at each light. Switch assuming is good cuz all other lights work, from what and how much i can see I dont have a pinched wire all fuses good. Bulbs look good, the odds they all burn out at one time in one trip???..wouldnt think so.

 

You said you got power at each light but the lights dont work?
well sounds like you have some bulbsto replace.
I have never tried it before, but you can ohm out the bulb itself in between hot and ground.
there should be an element in it which creates light. But if it's burnt out, it will
likely have no connection between + and - and you will read ifinite.
