Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle’s battery to ensure safety during electrical work.

2. Check and Replace Refrigerant

Sub-steps:
1. Connect the manifold gauge set to the A/C service ports.
2. If the refrigerant level is low, recover the remaining refrigerant using a recovery machine.
3. Evacuate the A/C system for at least 30 minutes to remove moisture and contaminants.
4. Recharge the system with the correct amount of refrigerant, typically R-134a or R-1234yf as specified in the owner's manual.
Tools Required: Manifold gauge set, recovery machine, refrigerant canister.

3. Inspect and Replace A/C Compressor

Sub-steps:
1. Locate the A/C compressor on the engine bay.
2. Disconnect the electrical connector from the compressor.
3. Remove the drive belt from the compressor pulley.
4. Unbolt and remove the compressor from its mounting brackets.
5. Install the new compressor and reassemble in reverse order.
Tools Required: Socket set, wrench set.

4. Replace Cabin Air Filter

Sub-steps:
1. Locate the cabin air filter access panel, typically behind the glove compartment.
2. Remove the panel and extract the old filter.
3. Install a new cabin air filter, ensuring correct orientation.
4. Reassemble the access panel.
Tools Required: Flathead screwdriver (if needed).

5. Reconnect Battery

Reconnect the vehicle’s battery terminals securely.
