Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shock.
Ensure the vehicle is on a flat surface and the engine is cool.

2. Inspect and Replace Cabin Air Filter

Locate the cabin air filter compartment, typically behind the glove box.
Remove the glove box by unscrewing the retaining screws.
Take out the old cabin air filter and inspect for dirt or blockages.
Insert a new cabin air filter (refer to owner’s manual for specifications).
Reassemble the glove box.

3. Check and Recharge A/C Refrigerant

Connect the A/C pressure gauge to the low-pressure service port.
Check the refrigerant level; if low, recharge the system according to manufacturer specifications.
Use the correct type of refrigerant (R-134a or R-1234yf as specified).

4. Test Blower Motor

Locate the blower motor, which is usually under the dashboard on the passenger side.
Disconnect the wiring harness from the blower motor.
Apply direct power from a 12V battery to the motor to check for operation.
If the motor does not function, replace it with a new one.

5. Inspect A/C Compressor

Check the A/C compressor for any signs of physical damage or leaks.
Ensure the compressor clutch is engaging when the A/C is activated.
If the compressor does not engage, it may need replacing.

6. Replace Blown Fuses

Locate the fuse box and check for any blown fuses related to the A/C system.
Replace any blown fuses with the same amperage as specified in the owner’s manual.
