Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Recharge Refrigerant

Tools Required: AC manifold gauge set, refrigerant, safety goggles, gloves.
If refrigerant levels are low, connect the low-pressure side of the manifold gauge to the service port.
Start the engine and turn on the AC to the maximum setting.
Read the pressure gauge; if low, add the appropriate type of refrigerant (usually R-134a for older models or R-1234yf for newer ones) until levels are within the manufacturer's specifications.

3. Inspect and Replace the Cabin Air Filter

Tools Required: Screwdriver set.
Locate the cabin air filter access panel (usually under the glove box).
Remove the panel and take out the old cabin air filter.
Inspect for dirt and debris; replace with a new filter if necessary.

4. Test and Replace AC Compressor (if faulty)

Tools Required: Socket set, torque wrench, refrigerant recovery machine (if needed), new AC compressor.
Remove the drive belt from the AC compressor by loosening the tensioner.
Disconnect the electrical connector and refrigerant lines from the compressor.
Remove the compressor from its mounting brackets.
Install the new compressor, ensuring it is properly aligned and secured.
Reconnect the refrigerant lines and electrical connectors.

5. Finalize and Reassemble

Reinstall any panels removed for access.
Reconnect the battery.
Run the AC for a few minutes and check for proper operation and any unusual noises.
