Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety.

2. Check and Recharge Refrigerant

Use a manifold gauge set to check the refrigerant pressure.
If low, locate and fix any leaks in the system before recharging.
Recharge the system with the correct type and amount of refrigerant (e.g., R-134a).

3. Inspect and Replace AC Compressor

Remove any components obstructing access to the AC compressor.
Unplug the electrical connector from the AC compressor.
Remove the compressor mounting bolts using a socket set.
Replace the compressor with a new OEM or quality aftermarket part.
Reinstall all components and reconnect the electrical connector.

4. Replace Cabin Air Filter

Locate the cabin air filter access panel (typically behind the glove box).
Remove the filter by unclipping it from its housing.
Install a new cabin air filter according to the manufacturer's specifications.

5. Test AC System

Reconnect the vehicle battery.
Start the engine and turn on the AC to the maximum setting.
Monitor for cool air and check for any unusual sounds.
