Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid electrical shorts.

2. Address Refrigerant Level

Tools Required: Manifold gauge set, refrigerant.
Connect the manifold gauges to the service ports on the AC system.
Check the low and high-pressure readings to determine if the refrigerant level is low.
If low, add the appropriate type of refrigerant (R-134a) as specified in the owner's manual.

3. Inspect and Replace Components

Tools Required: Socket set, wrenches, multimeter.
If the compressor is not engaging, check the compressor relay:
- Remove the relay from the fuse box.
- Use a multimeter to test for continuity.
- Replace the relay if faulty.
Inspect the AC compressor for any signs of damage or wear. Replace if necessary.

4. Clean or Replace Cabin Air Filter

Tools Required: Screwdriver (if needed).
Locate the cabin air filter housing (usually behind the glove compartment).
Remove the old filter and clean the housing.
Install a new cabin air filter, ensuring it is oriented correctly.

5. Reconnect Battery and Test

Reconnect the vehicle's battery.
Start the vehicle and set the AC to maximum cooling.
Monitor the system for proper operation and listen for unusual noises.
