Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle battery to ensure safety during the repair process.

2. Inspect and Replace Cabin Air Filter

Tools Required: Flathead screwdriver, replacement cabin air filter.
Remove any screws or clips holding the cabin air filter cover in place.
Take out the old cabin air filter and check for dirt or blockages.
Install the new cabin air filter, ensuring it is oriented correctly as per the airflow direction.

3. Check and Replace Blower Motor

Tools Required: Socket set, multimeter.
Locate the blower motor, usually found under the dashboard on the passenger side.
Disconnect the electrical connector from the blower motor.
Using a multimeter, test for voltage at the connector while operating the AC.
If no voltage is present, check the blower motor relay and fuses.
If voltage is present but the motor does not operate, remove the blower motor and replace it with a new one.
Reconnect the blower motor and electrical connector.

4. Recharge Refrigerant

Tools Required: Refrigerant gauge set, refrigerant canister.
Connect the refrigerant gauge set to the AC service ports.
Check the pressure readings; if low, add refrigerant according to manufacturer specifications.
Monitor the system while adding refrigerant to avoid overcharging.

5. Final Assembly

Reconnect the vehicle battery and ensure all connections are secure.
Test the AC system for proper function and check for any unusual noises.
