Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shock.

2. Inspect and Recharge Refrigerant

Tools Required: Manifold gauge set, refrigerant canister, AC vacuum pump.
Sub-steps:
1. Connect the manifold gauge set to the low and high pressure service ports.
2. Start the engine and turn on the AC to the maximum setting.
3. Check the pressure readings; compare them with the manufacturer's specifications.
4. If low, proceed to recharge the system.
5. Use an AC vacuum pump to evacuate the system for about 15-30 minutes to remove moisture.
6. Add the correct amount of refrigerant as specified in the owner’s manual.

3. Check and Replace AC Components

Tools Required: Socket set, screwdrivers, torque wrench.
Sub-steps:
1. If the compressor is not engaging, check the electrical connections and fuses related to the AC system.
2. Inspect the AC compressor for signs of wear or damage.
3. If faulty, remove the AC compressor by disconnecting the electrical connections and refrigerant lines.
4. Install the new compressor and torque all connections to the manufacturer’s specifications.
5. Reconnect the battery and test the AC system again.

4. Replace Cabin Air Filter

Tools Required: None needed, but a flathead screwdriver may assist.
Sub-steps:
1. Open the glove compartment and remove any contents.
2. Locate the cabin air filter access panel.
3. Remove the panel and take out the old filter.
4. Install the new cabin air filter, ensuring proper orientation.
5. Reattach the access panel and close the glove compartment.
