Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the vehicle battery to ensure safety while working on electrical components.
2. Inspect Rear HVAC Control
  • Reconnect the battery and turn on the vehicle.
  • Test the rear HVAC control settings and ensure they are operational.
3. Check Rear Blower Motor
  • Remove the rear blower motor cover using a socket set.
  • Disconnect the electrical connector from the blower motor.
  • Use a multimeter to check for voltage at the connector when the rear AC is activated.
    • If there is no voltage, trace wiring back to the control panel for damage.
    • If voltage is present, replace the rear blower motor.
4. Examine Ductwork
  • Inspect the rear AC ducting for any visible obstructions or damage.
  • If blockages are found, remove them carefully.
  • If ductwork is damaged, replace it as necessary.
5. Check Refrigerant Levels
  • Connect a refrigerant gauge to the service ports of the AC system.
  • Verify that the refrigerant levels are within the manufacturer's specifications.
  • If low, add the appropriate refrigerant type as specified in the owner's manual.
6. Replace Blown Fuses
  • Locate the fuse box and identify the fuse for the rear AC system.
  • Remove the fuse and check if it is blown.
  • If blown, replace it with a new fuse of the same amperage rating.
