Solution

1. Preparation

Gather all necessary tools and safety equipment (gloves, goggles).
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Recharge Refrigerant

Tools Required: Refrigerant gauge set, refrigerant canister, safety goggles, gloves.
Sub-steps:
1. Connect the refrigerant gauge set to the service ports on the AC system (low and high side).
2. Read the pressure levels; refer to the manufacturer's specifications for acceptable ranges.
3. If the refrigerant is low, follow the instructions on the refrigerant canister to recharge the system.

3. Inspect and Replace AC Compressor

Tools Required: Socket set, torque wrench, AC compressor replacement.
Sub-steps:
1. Disconnect the vehicle's battery to prevent any electrical issues.
2. Remove any components obstructing access to the AC compressor.
3. Disconnect the AC lines from the compressor (use a line wrench to avoid damaging the fittings).
4. Unbolt the AC compressor from its mounting brackets and remove it.
5. Install the new AC compressor, tightening bolts to manufacturer specifications.
6. Reconnect the AC lines securely, ensuring no leaks.

4. Replace Cabin Air Filter

Tools Required: None specifically needed but a flat-blade screwdriver may be helpful.
Sub-steps:
1. Locate the cabin air filter compartment, usually behind the glove box.
2. Remove the panel covering the filter by pressing tabs or unscrewing screws.
3. Take out the old filter and clean the compartment.
4. Install the new cabin air filter in the correct orientation.

5. Electrical System Check

Tools Required: Multimeter.
Sub-steps:
1. Inspect the AC fuse located in the fuse box and replace if blown.
2. Use a multimeter to test the AC relay for continuity.
3. If the relay is faulty, replace it.
