Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: AC manifold gauge set, multimeter, socket set, torque wrench, safety goggles, gloves.

2. Check and Recharge Refrigerant

Sub-steps:
- Locate the AC service ports on the low and high-pressure sides.
- Connect the refrigerant gauge set to the service ports.
- Read the pressures on both sides; if low, proceed to recharge.
- Use the appropriate refrigerant type (usually R-134a) and fill to the recommended level.

3. Inspect and Replace AC Compressor

Sub-steps:
- Disconnect the battery to ensure safety.
- Remove any components obstructing access to the AC compressor.
- Use a socket set to unbolt the compressor from its mounting brackets.
- Disconnect the electrical connector and refrigerant lines (ensure to capture any residual refrigerant safely).
- Install the new AC compressor by reversing the disassembly steps.
- Torque all bolts to manufacturer specifications.

4. Check and Replace Cabin Air Filter

Sub-steps:
- Locate the cabin air filter housing, usually behind the glove compartment.
- Remove the glove compartment to access the filter.
- Replace the old filter with a new one, ensuring proper orientation.
