Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to avoid electrical shock.

2. Check Refrigerant Level

Connect a manifold gauge set to the AC service ports.
Start the engine and turn the AC to the maximum setting.
Read the pressure on the low and high sides of the system.
If the pressure is low, proceed to recharge the system with the appropriate refrigerant (R-1234yf or R-134a depending on your specific model).

Tools Required:

Manifold gauge set
Refrigerant canister
Safety goggles
Gloves

3. Inspect and Replace AC Compressor

Remove the drive belt from the AC compressor.
Disconnect electrical connectors from the AC compressor.
Unbolt and remove the AC compressor from its mounting.
Install the new compressor in reverse order, ensuring proper torque specifications for bolts (typically 18-25 ft-lbs).
Reconnect all electrical connections and the drive belt.

4. Replace Cabin Air Filter

Locate the cabin air filter access panel, usually found behind the glove box.
Remove the glove box to access the filter compartment.
Remove the old filter and install the new one, ensuring it is oriented correctly.
Reassemble the glove box.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and turn on the AC.
Monitor the air temperature coming from the vents to ensure it is cold.
