1990 Rear Window Electrical issue

[CelBlazer702]

I'm attempting to fix the power rear window on my newly purchased 1990 Blazer. I have no power going to the dash switch. I checked both circuit breakers and they both ohmed out good. I probed the pink wire going into the fuse box and it's dead. Wondering what the next step is. Remove the fuse box and trace the pink wire to find a short or cut wire somewhere? Where is the pink wire fed from?

If the fuse ok on the wire, check the fusible link further towards the battery

Turns out the 30 Amp Circuit Breaker was bad even though it had no resistance on the meter. I have full power now going all the way back to the connector at the motor via a test light. Plugged the motor in and nothing. I'm thinking the motor may be bad, or the other 30 Amp Circuit Breaker is also bad. I'm going to bench test the motor tomorrow and see if it's bad, or if I have some other wiring issue going on.
