Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.

2. Replace Cabin Air Filter

Locate the cabin air filter compartment, usually behind the glove box.
Remove the glove box by detaching it from the hinges.
Take out the old cabin air filter and inspect for dirt or damage.
Install the new cabin air filter, ensuring it is oriented correctly.
Reassemble the glove box.

3. Repair or Replace Blower Motor

Access the blower motor, typically located under the dashboard on the passenger side.
Disconnect the electrical connector from the blower motor.
Remove the screws or bolts securing the blower motor to the housing.
If testing reveals the blower motor is defective, replace it with a new one.
Reconnect the electrical connector and secure the motor in place.

4. Recharge A/C System

Connect a refrigerant gauge to the A/C service ports.
Check the pressure readings; if low, proceed to recharge the A/C system with the appropriate refrigerant.
Follow the manufacturer’s specifications for the refrigerant type and amount.
Start the engine and run the A/C to ensure proper operation.

5. Reassemble Dashboard Components

If any dashboard components were removed, ensure they are reinstalled correctly.
Reconnect the vehicle battery.
