Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery before beginning work on the AC system.

2. Check and Recharge Refrigerant

Tools Required: Manifold gauge set, refrigerant canister, safety goggles, gloves.
Connect the manifold gauges to the AC service ports (low and high side).
Check the pressure readings:
- If low, add the appropriate refrigerant type (R-134a) according to manufacturer specifications.
- Monitor the gauges during the refill to prevent overcharging.

3. Inspect AC Compressor and Clutch

Tools Required: Socket set, torque wrench.
Locate the AC compressor (usually at the front of the engine).
Visually inspect for leaks, cracks, or damage.
Check the AC clutch:
- If not engaging, test the electrical connection with a multimeter to ensure it’s receiving power.
- If faulty, replace the AC compressor.

4. Replace Cabin Air Filter

Tools Required: None, or a flathead screwdriver (if needed for access).
Open the glove compartment and locate the cabin air filter access panel.
Remove the old filter and inspect for dirt and debris.
Install the new cabin air filter, ensuring it is oriented correctly according to airflow direction.

5. Test AC System

Reconnect the battery and start the vehicle.
Turn the AC system to maximum and monitor the air temperature from the vents.
Ensure that the AC compressor engages and that cold air is blown through the vents.
