Blower motor only works on hi speed 01 ranger 3.0?
Most likely the resister is burnt out. When you use less than full blower, the blower speed switch shunts the 12v power though a resister to drop the voltage to the blower motor, slowing the blower speed. When the multi-speed resister is burnt out, it is, 'open circuited'. So no electricity can pass though to the blower. When the blower switch is on 'full', the resister is bypassed, allowing full power to the fan motor for maximum speed. It should be located under that dashboard in most vehicles. Just trace the wires from the switch to the resister. Warning: a working resister can get very hot when power is going though it.

What could cause the heater blower to stop working even after it and the heater control was replaced on a 1992 Ford Thunderbird?
You still have a blower resister assembly, wiring, and a blower motor itself, in that system. Any one of those could have a problem. You need to use a test light at the blower motor connector and see if you are getting both power and ground. If you are missing a ground, most likely you have a bad blower resister assembly. If you are mssing power, check fuses and wiring. If you have both power and ground, and the motor isn't working, you need a blower motor. I have also found that sometimes tapping with a screwdriver handle on the motor will make it come on, and if that is the case, then again, you have a bad blower motor.
