Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and set the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Cabin Air Filter

Tools Required: Socket set, flathead screwdriver.
Locate the cabin air filter compartment, typically behind the glove box.
Remove the glove box by unscrewing any screws and detaching the clips.
Take out the old cabin air filter and inspect for dirt and debris.
Install a new cabin air filter, ensuring it is oriented correctly.
Reassemble the glove box.

3. Check and Recharge Refrigerant

Tools Required: Manifold gauge set, refrigerant canister.
Connect the manifold gauges to the high and low pressure service ports.
Start the engine and turn on the AC to the maximum setting.
Monitor the pressure readings; if low, proceed to recharge with refrigerant according to the manufacturer's specifications (typically R-134a).
Disconnect the gauges and ensure all caps are securely replaced.

4. Inspect and Replace Blower Motor (if necessary)

Tools Required: Socket set, multimeter.
Locate the blower motor, usually found under the dashboard on the passenger side.
Disconnect the electrical connector and remove the mounting screws.
Test the blower motor with a multimeter to check for proper operation.
If faulty, replace with a new blower motor.
Reinstall the blower motor and reconnect the electrical connector.
