Solution

1. Preparation

Gather tools: A/C pressure gauge, multimeter, socket set, vacuum pump, refrigerant refill kit.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Check Refrigerant Level

Connect the A/C pressure gauge to the service port on the low-pressure side of the A/C system.
Read the pressure and compare it to the manufacturer's specifications.
If the pressure is low, proceed to the next step to recharge.

3. Recharge the A/C System

Attach the refrigerant refill kit to the low-pressure service port.
Open the valve slowly and allow refrigerant to enter until the correct pressure is achieved.
Monitor the system to avoid overcharging, which can cause damage.

4. Inspect and Replace Components

If refrigerant levels are adequate, check the A/C compressor:
- Remove any obstructions and ensure proper electrical connections are secure.
- If the compressor is failing, replace it.
Inspect the cabin air filter:
- Remove the filter from its housing.
- If dirty, replace with a new filter.

5. Verify Functionality

Reconnect the battery and turn on the vehicle.
Set the A/C to maximum and observe system operation.
Check for cold air output from the vents.
