Condition
Some customers may comment that the blower will only work on low speeds or has become inoperative.
Correction
REPLACE THE BLOWER MOTOR RESISTOR AND RESISTOR MODULE CONNECTOR.
Replace the blower motor resistor and module connector using the following procedure:
Remove the blower fuse.
Fullsize Trucks and Utility Vehicles - Htr A/C & HVAC 1 fuses
Midsize Utility Vehicles - Blower Fuse 35 located in the Underhood Fuse Block
Lower the hush panel or close-out panel enough to gain access to the resistor module connector.
Disconnect the connector from the resistor module.
Remove the tape from the wiring harness to expose the wiring.
Cut the wires back far enough from the connector to eliminate any melted insulation on the wire.
Tip
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.
Install the new connector. Use the yellow splice sleeves provided with the connector.
Install new blower motor resistor.
Reinstall the fuse or connector block. Test the blower motor to make sure all speeds are functional.
Reinstall the hush panel/close-out panel.
