REMOVAL & INSTALLATION
See Figure 1
The blower switch resistor is used to control the blower motor speed. Based upon where the blower switch is positioned, a different current level will be sent to the blower motor. The current from the blower switch to the blower motor is sent through the resistor assembly.
A blower motor that only works on one speed is usually a good indication that the resistor has failed and needed replacing.
The blower motor switch resistor is installed to the blower duct, next to the blower motor assembly. It is secured in place with two screws.
- Disconnect the negative battery cable.
- Unfasten the wire harness attached to the resistor switch.
- Remove the two resistor retaining screws and remove the resistor assembly.
- Position the resistor in place and secure using the retaining screws.
- Fasten the wire harness to the rear of the switch resistor.
- Connect the negative battery cable. Test the blower motor on all speeds.
