Solution
1. Preparation
  • Gather tools: OBD-II scanner, multimeter, socket set, flathead screwdriver, and safety glasses.
  • Disconnect the battery to prevent electrical shock.
2. Inspect and Replace Cabin Air Filter
  • Locate the cabin air filter access panel, typically found behind the glove compartment.
  • Remove the screws or clips securing the panel and take out the old cabin air filter.
  • Clean the filter housing area before installing a new filter.
  • Install the new cabin air filter in the correct orientation.
3. Blower Motor Testing and Replacement
  • Remove the blower motor cover by unscrewing it from the housing.
  • Disconnect the electrical connector from the blower motor.
  • Use a multimeter to check for power at the connector when the fan is activated.
  • If no power is present, check the blower motor resistor and replace if faulty.
  • If power is present but the blower motor doesn’t operate, remove the motor and replace it with a new unit.
4. Verify Ductwork
  • Inspect the HVAC ductwork for any signs of blockage or disconnection.
  • Remove any obstructions found and ensure all duct connections are secure.
