I have a problem with my interior blower fan on a 90 sc. It doesn't operate. Here's what I've checked so far:
- Fan motor itself (applied power to it directly and it works fine)
- checked the resistor pack in the case.. its fine as well.
- swapped both the motor speed swicth and the a/c selector switches on the dash.. no fix.
- checked the 80A fuse under the hood.. its fine.
- checked the 30A fuse under the dash.. its fine.
- swapped the ignition switch.. no change
So what I'm left with appears to be a wire issue somewhere, but I don't have any good wiring diagrams for that.
My factory manual doesn't cover it, nor does the Haynes book. I have a complete but difficult to read Chilton's diagram,
but my eyesight isn't good enough for the microscopic print.
Does anyone have a circuit diagram, or insight, ideas that they could share?
TIA
