Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turned off.
Disconnect the vehicle's battery to avoid any electrical issues while working.

2. Replace Cabin Air Filter

Locate the cabin air filter compartment (usually behind the glove box).
Remove the glove box by detaching the hinges and any screws.
Take out the old cabin air filter and inspect its condition.
Insert a new cabin air filter (make sure it is oriented correctly).
Reassemble the glove box.

3. Inspect and Replace A/C Compressor (if necessary)

Locate the A/C compressor in the engine bay.
Disconnect the electrical connector from the compressor.
Remove the refrigerant using an A/C recovery machine.
Unscrew the mounting bolts and remove the old compressor.
Install the new compressor by reversing the removal process.
Reconnect the electrical connector and refill the refrigerant to the manufacturer's specifications.

4. Check and Replace Blower Motor (if necessary)

Access the blower motor, usually located behind the dashboard.
Disconnect the electrical connector and remove the mounting screws.
Take out the blower motor and inspect it for any damage or debris.
Install a new blower motor if the old one is defective.
Reconnect the electrical connector and secure the motor in place.
