Solution

1. Preparation

Gather necessary tools and parts, and park the vehicle on a level surface.
Disconnect the negative battery terminal to ensure safety while working on the electrical components.

2. Check Refrigerant Levels

Tools Required: Refrigerant gauge
Connect the refrigerant gauge to the low-pressure service port.
Check the pressure readings; if low, proceed to recharge the system.

3. Recharge the AC System

Parts Required: R-134a refrigerant
Attach the refrigerant can to the gauge and open the valve.
Allow the refrigerant to flow into the system until the correct pressure is reached (typically between 30-40 psi on the low side).
Disconnect the gauge and ensure the system is sealed.

4. Inspect and Replace Cabin Air Filter

Tools Required: Screwdriver or trim removal tool
Locate the cabin air filter access panel (usually under the glove box).
Remove the access panel and extract the old cabin air filter.
Insert a new filter, ensuring it is oriented correctly, and reattach the access panel.

5. Inspect and Clean AC Condenser

Tools Required: Hose or soft brush
Inspect the AC condenser for any debris or damage.
Clean the condenser using a gentle stream of water or a soft brush to remove dirt or obstructions.

6. Test AC Compressor

Tools Required: Multimeter
Reconnect the battery and turn on the AC system.
Use a multimeter to check for voltage at the AC compressor clutch connector.
If no voltage is present, trace back the wiring for faults or issues with the AC control module.
