Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock.
Ensure the vehicle is parked on a level surface.

2. Inspect and Replace the Cabin Air Filter

Locate the cabin air filter housing, typically behind the glove box.
Remove the glove box by detaching any screws and releasing the clips.
Take out the old cabin air filter and inspect it; replace if dirty.
Install the new cabin air filter and reassemble the glove box.

3. Check and Recharge Refrigerant

Connect the manifold gauge set to the low and high-pressure service ports.
Check refrigerant levels; if low, proceed to recharge.
Use the appropriate R-134a refrigerant and a recharge kit.
Add refrigerant until the pressures are within the manufacturer's specifications.

4. Test the AC Compressor

With the engine running and the AC set to high, check if the AC compressor clutch engages.
If it does not engage, check the voltage at the compressor connector.
If voltage is present and the clutch does not engage, replace the AC compressor.

5. Inspect and Replace the AC Relay

Locate the AC relay in the fuse box; refer to the owner’s manual for exact location.
Remove the relay and check for continuity using a multimeter.
Replace the relay if it is faulty.
