Resistor Module Connector and Blower Motor Resistor Replacement
1. Remove the blower fuses (Htr A/C & HVAC 1 fuses).
2. Lower the close-out panel enough to gain access to the resistor module connector.
3. Disconnect the connector from the resistor module.
Note
Connector replacement is required even if the connector was replaced on a previous service repair.
4. Remove the tape from the wiring harness to expose the wiring.
5. Cut the wires back far enough from the connector to eliminate any melted insulation on the wire.
Note
Use the old connector as a map for splicing the wires for the new connector. Be sure to use the correct crimping tool from the terminal repair kit J
38125. Use only Duraseal splice sleeves. Other splice sleeves may not protect the splice from moisture or provide a good electrical connection.
6. Install the new connector. Use the yellow splice sleeves provided with the connector.
7. Install the new blower motor resistor.
8. Reinstall the fuses. Test the blower motor to make sure all speeds are functional.
9. Reinstall the hush panel/close-out panel.
