TAIL LIGHT FUSE IS GOOD AND THERE IS POWER TO FUSE BLOCK
DASH AND TAIL LIGHTS NOT WORKING, on 1990 Ford Probe
You need a wiring diagram to trace the circuit. I suspect the fuse is powered from the headlamp switch. If so, check power at the switch. The headlamp switch could be the problem.
i'm having the same problem right now.. hoping you found an answer
