Steps
- Raise the truck and remove the wheel
Loosen the lug nuts while the wheel is on the ground. Lift the truck at an approved point, support it securely on a jack stand, then remove the wheel and center cap hardware as applicable.
- Remove the inner wheel-well liner
Remove the mud-flap fasteners and clips, then release the liner screws and bolts. Ease the liner out of the fender and move the vacuum lines from the reservoir aside without kinking them.
- Unplug and remove the resistor
Release the resistor connector lock and unplug the wiring. Remove the two retaining bolts, then withdraw the resistor from the heater housing while checking the connector for heat damage.
- Install the new resistor
Seat the replacement resistor fully in the heater housing and secure its two bolts. Reconnect the harness until its lock engages, keeping the wires clear of sharp edges and hot components.
- Restore the liner and vacuum lines
Reconnect the vacuum lines to the reservoir, then position the liner and engage its edges. Reinstall the bolts, screws, clips, and mud flap fasteners so the liner cannot rub against the tire.
- Reinstall the wheel and test fan speeds
Mount the wheel and hand-start the lug nuts. Lower the truck and tighten the lugs to the vehicle specification in a star pattern, then run the blower at each speed to confirm operation.
Check your vehicle’s repair manual for exact specifications and fit.
