Solution

1. Preparation

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

2. Check and Recharge Refrigerant

Tools Required: AC manifold gauge set, refrigerant can, safety goggles, gloves
Connect the low-pressure side of the manifold gauge to the AC service port.
Read the pressure; if low, proceed to recharge the system.
Attach the refrigerant can to the manifold gauge and open the valve to let refrigerant into the system.
Monitor the pressure gauge to ensure it reaches the manufacturer's specified level (typically between 30-40 psi for R-134a).

3. Inspect and Replace AC Compressor

Tools Required: Socket set, torque wrench, AC compressor replacement
Visually inspect the AC compressor for any signs of damage or leaks.
If faulty, disconnect the electrical connector and remove the mounting bolts.
Take off the compressor and replace it with a new one, ensuring to align properly.
Reconnect the electrical connector and tighten the mounting bolts to the specified torque (consult manufacturer specifications).

4. Replace Cabin Air Filter

Tools Required: None or basic hand tools for access
Locate the cabin air filter compartment (usually behind the glove box).
Remove the cover and take out the old filter.
Install the new cabin air filter, ensuring it is oriented correctly for airflow direction.

5. Recharge System and Test

Reconnect the battery.
Run the engine and set the AC to max cool.
Use the manifold gauge to check the system pressure again.
Verify the AC compressor engages and cold air is being produced from the vents.
