Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to avoid electrical issues.

2. Inspect and Repair the AC Compressor

Tools Required: Socket set, torque wrench, AC manifold gauge set.
Locate the AC compressor in the engine bay.
Check for visible signs of damage or oil leaks around the compressor.
If the compressor is not engaging, verify the electrical connections and relay.
If faulty, remove the AC compressor by disconnecting the electrical connector and the refrigerant lines (be cautious of refrigerant release).
Replace the compressor with a new unit, and secure it with the specified torque settings.

3. Recharge the AC System

Tools Required: AC manifold gauge set, refrigerant.
Connect the manifold gauges to the high and low pressure service ports.
Start the engine and set the AC to maximum cooling.
Add refrigerant according to the manufacturer's specifications, monitoring the pressure gauges to ensure proper levels.
Disconnect the gauges and check for leaks around the service ports.

4. Replace Cabin Air Filter

Tools Required: None, but a flathead screwdriver may be needed for some models.
Locate the cabin air filter access panel, typically under the glove compartment.
Remove the old filter and inspect for dirt or blockages.
Install a new cabin air filter, ensuring it is oriented correctly.

5. Test the AC System

Reconnect the battery.
Start the engine and turn on the AC system to the coldest setting.
Monitor the temperature of the air coming from the vents to confirm it is blowing cold.
