Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Recharge Refrigerant

Tools Required: Refrigerant gauge set, refrigerant canister, safety goggles, gloves.
Connect the low-pressure side of the gauge set to the AC service port.
If the refrigerant level is low, attach the refrigerant canister to the same port.
Start the engine and turn on the AC to the maximum setting.
Slowly open the canister valve to add refrigerant while observing the pressure gauge. Do not exceed the manufacturer's specified pressure.

3. Inspect and Replace AC Compressor

Tools Required: Socket set, torque wrench, AC compressor removal tool.
Remove the serpentine belt by loosening the tensioner pulley.
Disconnect electrical connectors and refrigerant lines from the compressor.
Remove mounting bolts and take out the old compressor.
Install the new compressor, ensuring all bolts are torqued to manufacturer's specifications.
Reconnect refrigerant lines and electrical connectors.

4. Replace Cabin Air Filter

Tools Required: None (if applicable).
Locate the cabin air filter compartment, typically behind the glove box.
Remove the glove box to access the filter.
Take out the old filter and install the new one, ensuring proper orientation.
