Troubleshooting Steps

Check the Rear Blower Motor

  • Listen for Operation: When you turn on the rear AC, listen for the sound of the blower motor. If you hear it running, the issue may not be with the blower itself.
  • Accessing the Motor: The rear blower motor is often located behind a panel in the rear of the vehicle. You may need to remove this panel to inspect it.

Inspect Fuses

  • Check Fuses: Locate and check the relevant fuses for the rear AC system. Common fuses to check include:

- Fuse #60 (40 Amp) in the multi-fuse relay box

- Fuse #3 (7.5 Amp) under the driver's side dash

  • Replace Blown Fuses: If any fuses are blown, replace them and test the AC again.

Examine Blend Door Actuator

  • Functionality: A malfunctioning blend door actuator can prevent air from flowing through the vents. If you suspect this is an issue:

- Remove the right rear panel cover to access it.

- Ensure that all ducts are connected properly.

Check for Clogs or Leaks

  • Inspect Ducts: Look for any clogs or disconnections in the ductwork that could be obstructing airflow.
  • Refrigerant Levels: Low refrigerant levels can also affect AC performance. If you suspect a leak, consider having a professional check and recharge your system.

Test Controls

  • Control Settings: Ensure that both front and rear climate control settings are correctly adjusted. Sometimes, incorrect settings can lead to perceived AC failure.
