Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the vehicle's battery to ensure safety.

2. Check and Recharge Refrigerant

Tools Required: Manifold gauge set, refrigerant canister
Connect the manifold gauge set to the high and low-pressure ports of the A/C system.
Check the pressure readings and compare them to manufacturer specifications.
If refrigerant is low, attach the refrigerant canister to the low-pressure port.
Open the valve on the refrigerant canister and allow refrigerant to enter the system until the proper level is reached.
Disconnect the manifold gauge set and replace any caps on the service ports.

3. Replace Cabin Air Filter

Tools Required: Screwdriver set
Locate the cabin air filter housing, typically behind the glove box.
Remove the screws or clips securing the glove box and lower it down.
Remove the old cabin air filter by sliding it out of the housing.
Insert a new cabin air filter (ensure the airflow direction is correct).
Reassemble the glove box and secure it with screws.

4. Inspect and Replace A/C Compressor (if necessary)

Tools Required: Socket set, torque wrench, A/C compressor replacement
Locate the A/C compressor in the engine bay.
Disconnect electrical connectors and refrigerant lines (ensure proper recovery of refrigerant).
Remove the mounting bolts securing the compressor.
Install the new A/C compressor and torque the bolts to manufacturer specifications.
Reconnect the refrigerant lines and electrical connectors.

5. Test the A/C System

Reconnect the vehicle's battery.
Start the engine and turn on the A/C to the maximum setting.
Monitor the A/C performance for cool air and listen for unusual noises.
