Solution

1. Preparation

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

2. Check Refrigerant Level

Tools Required: Manifold gauge set
Connect the manifold gauge set to the low and high service ports of the AC system.
Check the pressure readings against manufacturer specifications; if low, proceed to recharge the system.

3. Recharge the AC System

Parts Required: Refrigerant (R-134a)
If the refrigerant level is low, locate the low-pressure service port (usually a blue cap).
Attach the refrigerant can to the low-pressure port.
Open the valve slowly to allow refrigerant to enter the system while monitoring the pressure gauge.
Stop when the system reaches the optimal pressure according to specifications.

4. Inspect and Replace the Cabin Air Filter

Tools Required: Screwdriver or pliers (if applicable)
Locate the cabin air filter housing (usually under the glove box).
Remove the cover and take out the old cabin air filter.
Install a new cabin air filter, ensuring the airflow direction matches the markings inside the housing.

5. Test AC Operation

Reconnect the negative battery terminal.
Start the vehicle and turn on the AC to the maximum setting.
Observe if cold air starts to flow from the vents.
