Default OT Ford semi truck, cab heater not working

OK, thanks. Where is that resistor usually, under the dash, or in the
engine compartment?


It's somewhere in the airstream of the heater system. If the
blower is on but not spinning [i.e. jammed], the resister often
dies a quick death. But the fastest position has no resistor in
series; so if that is also dead, look elsewhere.
