Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety during the repair.

2. Recharge Refrigerant

Tools Required: AC manifold gauge set, refrigerant canister, safety goggles, gloves.
Sub-steps:
1. Connect the low and high pressure sides of the manifold gauge to the AC service ports.
2. Check the pressure readings; if low, proceed to recharge.
3. Attach the refrigerant canister to the low-pressure side.
4. Open the valve on the refrigerant canister and allow the system to recharge until proper levels are reached (typically 30-40 psi on low side).
5. Disconnect the manifold gauge and replace the service port caps.

3. Inspect and Replace AC Compressor

Tools Required: Socket set, torque wrench, AC compressor removal tool.
Sub-steps:
1. Remove the drive belt from the AC compressor.
2. Disconnect the electrical connector from the compressor.
3. Unscrew the mounting bolts and remove the compressor from its bracket.
4. Install the new compressor, ensuring proper alignment.
5. Torque the mounting bolts to manufacturer specifications.
6. Reconnect the electrical connector and reattach the drive belt.

4. Replace Cabin Air Filter

Tools Required: None (just your hands).
Sub-steps:
1. Locate the cabin air filter housing (usually behind the glove compartment).
2. Remove the glove compartment to access the filter.
3. Slide out the old cabin air filter and replace it with a new one, ensuring correct orientation.
4. Reassemble the glove compartment.

5. Clean AC Condenser

Tools Required: Hose with nozzle, soft brush.
Sub-steps:
1. Locate the AC condenser in front of the radiator.
2. Use a soft brush to remove any debris or dirt from the condenser fins.
3. Spray water gently to clean off any remaining dirt without damaging the fins.
