Solution

1. Preparation

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

2. Replace Cabin Air Filter

Tools Required: Phillips screwdriver, replacement cabin air filter
Steps:
1. Locate the cabin air filter access door, usually found under the glove compartment.
2. Remove the screws securing the access door with the Phillips screwdriver.
3. Carefully slide out the old cabin air filter and inspect for dirt and debris.
4. Insert the new cabin air filter, ensuring it is oriented correctly (check the airflow direction).
5. Reattach the access door and secure with screws.

3. Inspect and Repair AC Compressor

Tools Required: Multimeter, AC manifold gauge set
Steps:
1. Reconnect the battery negative terminal.
2. Use the multimeter to check the voltage at the AC compressor connector; it should be around 12 volts when the AC is turned on.
3. If the compressor does not engage, check the AC relay and replace it if faulty.
4. If the compressor engages but does not cool, check the refrigerant level with the manifold gauge set and recharge if necessary.

4. Clear Any Blockages in Ducts

Tools Required: Vacuum cleaner, soft brush
Steps:
1. Inspect the AC ductwork for any visible obstructions.
2. Use a vacuum cleaner with a brush attachment to remove dust and debris from the vents.
3. Check for any kinks or damage in the duct hoses that may restrict airflow.
