Solution

1. Preparation

Gather all 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 mishaps.

2. Recharge the AC System

Tools Required: Manifold gauge set, AC refrigerant.
Connect the manifold gauge set to the AC service ports.
Start the engine and set the AC to max cooling with the blower on high.
Check the low and high-pressure readings; if low, proceed to recharge.
Add refrigerant as per manufacturer's specifications until the correct pressure is achieved.

3. Inspect and Replace the Cabin Air Filter

Tools Required: Screwdriver (if necessary).
Locate the cabin air filter compartment (usually behind the glove box).
Remove the cover and take out the existing filter.
Inspect for dirt and debris; replace with a new cabin air filter.

4. Test the AC Compressor

Tools Required: Multimeter.
Locate the AC compressor and check the electrical connector.
Use a multimeter to test for continuity; if there is no continuity, replace the compressor.
If the compressor engages but does not cool, further replacement may be necessary.

5. Check for Condenser Blockage

Visually inspect the AC condenser for debris or damages.
If blocked, clean the condenser with compressed air or remove debris carefully.
Replace the condenser if it is damaged or excessively corroded.
