Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Check and Replace the Cabin Air Filter

Tools Required: Screwdriver, replacement cabin air filter
Remove the glove compartment by unscrewing the hinge screws.
Carefully detach any clips holding the cabin air filter cover.
Remove the old cabin air filter and replace it with a new one, ensuring proper orientation.
Reassemble the glove compartment.

3. Inspect and Replace the Blower Motor

Tools Required: Socket set, multimeter, replacement blower motor
Locate the blower motor, usually found under the dashboard on the passenger side.
Disconnect the electrical connector from the blower motor.
Use a multimeter to check for voltage at the connector while the AC is on.
If there is voltage, remove the screws securing the blower motor and pull it out.
Replace with a new blower motor and secure it with screws. Reconnect the electrical connector.

4. Check the AC Compressor Functionality

Tools Required: AC gauge set
Remove the engine cover if necessary to access the AC compressor.
Connect the AC gauge set to the service ports on the compressor.
Start the engine and turn on the AC to monitor pressure readings, ensuring they are within manufacturer specifications.
If the compressor is not engaging, further diagnostics or replacement may be needed.

5. Verify Ducting and Vent Condition

Inspect the ducting for any loose connections or blockages.
Ensure vents are clear of any obstructions (e.g., debris or foreign objects).
If ducting is damaged, consider replacing any cracked or broken sections.
