Toyota Repair: 1982 Celica GT heater blower motor, heater blower resistor, celica gt

Question
Recently my heater blower motors operation became intermittant, became progressively worse, and then after smelling something like overheated electrical wiring - the blower quit altogether. I disconnected the blower motor and checked the voltage going into the motor. There is 12 volts there, and the fan switch turns the voltage on and off but there is only one voltage level. I checked the resistance of the motor and it was about one ohm. I figured that meant the windings were shorted out and bought another motor. However the new motor also tests about one ohm and when I connect it to the wires from the relay that have 12 volts - it doesn't run either! HELP! Now What?

Answer
I doubt that the new motor has a problem but you should test it anyway to eliminate it as the possible source of the problem.
Apply 12 volts directly to either one of the terminals on the motor and ground the other side, the motor should spin at full speed.
If it does, try replacing the heater blower resistor, it's located near the motor in the air duct, you may have to remove the glove box to get to it, the best way is to get the new one from the dealer so you will know what it looks like.
