Solution

1. Preparation

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

Tools Required:

OBD-II scanner
Refrigerant pressure gauge
Multimeter
Socket set
Torque wrench
Screwdrivers

2. Check and Replace the Cabin Air Filter

Locate the cabin air filter housing, usually behind the glove compartment.
Remove the glove compartment to access the filter.
Take out the old cabin air filter and inspect it for dirt and blockages.
Install a new cabin air filter (ensure it is oriented correctly).

3. Recharge the A/C System

Connect the refrigerant pressure gauge to the service port.
If the refrigerant level is low, follow the manufacturer’s guidelines to add the correct refrigerant type (R-134a or R-1234yf, as specified).
Monitor the pressure while adding refrigerant to ensure it reaches the optimal level.

4. Inspect and Replace A/C Components

If the compressor is not engaging, check electrical connections and fuses.
Use a multimeter to test for voltage at the compressor connector; if no voltage is present, trace the issue back to the A/C relay or control module.
If necessary, replace the A/C compressor or relay following the manufacturer’s service manual specifications.

5. Test the A/C System

Reconnect the battery and start the engine.
Turn on the A/C system to the maximum setting and monitor the air output.
Check for any unusual noises or vibrations during operation.
