Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to avoid any electrical issues.

2. Check and Refill Refrigerant

Remove the low-pressure service port cap on the AC system.
Connect a refrigerant gauge to the low-pressure port.
If refrigerant levels are low, use a refrigerant can to refill the system according to the manufacturer's specifications.
- Use R134a refrigerant (check for correct type).
- Follow the instructions on the refrigerant can for proper filling technique.
Disconnect the gauge and replace the service port cap.

3. Inspect and Replace Cabin Air Filter

Locate the cabin air filter access panel, usually behind the glove box.
Open the glove box and remove any obstructing panels.
Carefully pull out the old cabin air filter.
Insert the new cabin air filter, ensuring it is oriented correctly for airflow.
Reassemble the access panel and glove box.

4. Test AC Compressor Functionality

Reconnect the battery.
Start the engine and turn on the AC to max cool.
Observe the AC compressor clutch; it should engage. If it does not, further inspection of the electrical connections or compressor may be necessary.
If the compressor is faulty, replace it following the manufacturer’s specifications.
