Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is off.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Replace Cabin Air Filter
  • Locate the cabin air filter housing, usually found behind the glove compartment.
  • Remove the glove compartment by unscrewing any screws and unhooking it from its hinges.
  • Open the cabin air filter housing and remove the old filter.
  • Install the new cabin air filter, ensuring it is oriented correctly.
  • Reattach the glove compartment.
3. Inspect and Test Blower Motor
  • Locate the blower motor, typically found under the dashboard on the passenger side.
  • Disconnect the electrical connector from the blower motor.
  • Use a multimeter to test the voltage at the connector while operating the fan speed.
  • If no voltage is detected, trace wiring for faults; if voltage is present, replace the blower motor.
4. Check AC Refrigerant Level
  • Connect a refrigerant gauge set to the AC service ports.
  • Check the pressure readings against manufacturer specifications.
  • If low, recover the refrigerant and recharge the system with the correct type and amount of refrigerant.
5. Inspect Ductwork
  • Visually inspect all accessible ductwork for any obstructions or signs of damage.
  • If necessary, remove components to access deeper duct areas.
  • Clear any debris or blockages found in the ductwork.
