Solution

1. Preparation

Gather tools and parts needed. Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required:
- AC manifold gauge set
- Socket set
- Screwdriver set
- Refrigerant (if levels are low)

2. Check and Recharge Refrigerant

Connect the AC manifold gauge set to the low and high-pressure ports.
Read the pressure levels on both sides.
- If low, add refrigerant through the low-pressure port until the correct level is reached (refer to manufacturer specifications).
Disconnect the gauge set and check for leaks.

3. Inspect and Replace Components

AC Compressor:
- Locate the compressor and inspect the clutch and wiring.
- If damaged, remove the compressor using a socket set and replace it with a new unit.
Blend Door Actuator:
- Access the actuator (usually behind the dashboard).
- Remove screws and disconnect the actuator. Install a new actuator if it’s malfunctioning.

4. Replace Cabin Air Filter

Open the glove compartment and remove any fasteners or clips.
Take out the old cabin air filter and install a new one.
Reassemble the glove compartment.

5. Test AC System

Start the vehicle and turn on the AC to maximum cooling.
Monitor the temperature from the vents to ensure cold air is blowing.
