blower motor resistor---I'm about to replace mine and have replaced both my sister's Honda crv, and a buddy's Chevy Tahoe they all slowly lost one or more settings (high or low) and then eventually died
the heater resistor needs to be replaced it is mounted in the heater box next to the blower motor
The blower motor can be replaced on a 1995 Chevy truck by first disconnecting the battery. It helps to take a picture of the blower motor before dismantling, so that it can be put back easily. Disconnect all the wires from the motor, then remove the bolts holding it to the firewall. Replace with the new motor and bolt it in, then connect the wires. Reconnect the battery.
The blower motor works on only one speed. The blower motor resitor pack is defective and needs to be replaced. It is located on the blower housing in the engine compartment just below the blower motor.
If the blower only works on high the blower resistor is most likely the problem and should be replaced. On rare occasions if the car has blown the resistor more than once the blower motor shouuld be replaced.
Behind the right rear panel just under the blower motor itself. It has red and black wires that plug to the motor and to other clips that clip on it
On an auto temp system the blower motor resistor has failed and needs replaced.
The blower motor resistor pack is accessed from inside the vehicle, not from the engine compartment. Exactly where it is I cannot say. Follow the wires from the blower motor and you will find it.
