Hey all,

Just picked up a 92 mighty max 3.0 4x4 with a low 54k miles with no a/c from the factory. Everything works great except the blower motor.

The trucks wiring is unmolested save a trailer brake/light module that taps into a wire leading to a switch on the clutch pedal and a wire coming of the positive battery terminal, but otherwise seems to be self contained. The ABS light is illuminated, which I'm guessing is related to this.

The ecu was replaced by a mechanic at some point.

When I got the truck the radio fuse was blown, after replacing there's been no issue.

I've checked the battery, fuses, and fusible links, all test good. The rest of the fuse block gets power, but nothing at the "heater" fuse.

Any ideas?
