Steps
- Remove the lower access panel
Remove the screws beneath the glove compartment and lower the access panel. Keep the fasteners together and set the panel aside to expose the blower-resistor area.
- Disconnect and remove the resistor
Unplug the resistor harness and remove its retaining bolts with a swivel socket for access. Withdraw the resistor from the housing and inspect the connector for melted plastic or heat damage.
- Install the replacement resistor
Seat the new resistor fully in the housing and tighten its fasteners evenly. Reconnect the harness until its latch locks, then confirm the wiring is clear of the blower wheel.
- Refit the panel and test blower speeds
Reinstall the lower access panel and its screws. Turn the ignition on and test each blower speed; if a speed is still missing, inspect the connector and related circuit before replacing more parts.
Check your vehicle’s repair manual for exact specifications and fit.
