Solution

1. Preparation

Gather necessary tools and components.
Park the vehicle on a level surface and turn off the engine.
Disconnect the battery to ensure safety during repairs.

2. Check and Recharge Refrigerant

Tools Required: Manifold gauge set, refrigerant canister
Connect the manifold gauge set to the low and high-pressure service ports.
Start the engine and turn the AC to the maximum setting.
If the refrigerant level is low, add refrigerant according to the manufacturer's specifications (usually R134a).
Monitor the gauges to ensure the system reaches proper pressure levels.

3. Inspect and Replace AC Compressor

Tools Required: Socket set, torque wrench, AC compressor replacement
Remove any components obstructing access to the AC compressor.
Disconnect the AC lines from the compressor; use proper tools to prevent damage.
Unbolt the compressor from its mounting bracket.
Install the new compressor and torque bolts to the manufacturer's specifications.
Reconnect the AC lines and ensure they are sealed properly.

4. Check and Replace Cabin Air Filter

Tools Required: None (may require a screwdriver for certain models)
Locate the cabin air filter access panel, usually under the glove box.
Remove the access panel and take out the old cabin air filter.
Install a new cabin air filter, ensuring it is oriented correctly.

5. Test AC System

Reconnect the battery and start the engine.
Turn the AC system on to maximum and observe if cold air is now being produced.
Check for any unusual noises or leaks around the compressor and lines.
