Blower Motor Resistor Block

REMOVAL

WARNING:
- ON VEHICLES EQUIPPED WITH AIR-BAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIR-BAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
- THE BLOWER MOTOR RESISTOR BLOCK MAY GET VERY HOT DURING NORMAL OPERATION. IF THE BLOWER MOTOR WAS TURNED ON PRIOR TO SERVICING THE BLOWER MOTOR RESISTOR BLOCK, WAIT FIVE MINUTES TO ALLOW THE BLOWER MOTOR RESISTORS TO COOL BEFORE PERFORMING DIAGNOSIS OR SERVICE. FAILURE TO TAKE THIS PRECAUTION CAN RESULT IN PERSONAL INJURY.

CAUTION: Do not operate the blower motor with the blower motor resistor removed from the circuit. Failure to take this precaution can result in vehicle damage.

1. Disconnect and isolate the battery negative cable.
2. Remove the glove box from the instrument panel.

Blower Motor Resistor Block - Typical:

3. Disconnect the two wire harness connectors from the blower motor resistor block.
4. Remove the two screws that secure the blower motor resistor block to the HVAC housing.
5. Remove the resistor block from the HVAC housing.

INSTALLATION
1. Position the blower motor resistor block into the HVAC housing.
2. Install the two screws that secure the blower motor resistor block to the HVAC housing. Tighten the screws to 2 Nm (17 in. lbs.).
3. Connect the two wire connectors to the resistor block.
4. Install the glove box.
5. Reconnect the battery negative cable.
