Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves.

2. Recover and Recharge Refrigerant

Tools Required: AC recovery machine, refrigerant manifold gauge set, new refrigerant.
Sub-steps:
1. Connect the recovery machine to the AC service ports.
2. Recover any existing refrigerant according to local regulations.
3. Check for leaks in the system using a UV leak detector or soap solution.
4. If no leaks are found, proceed to recharge the system with the appropriate type and amount of refrigerant (typically R-134a).
5. Start the engine and turn on the AC to test for cold air.

3. Replace AC Compressor (if necessary)

Tools Required: Socket set, torque wrench, refrigerant oil, new compressor.
Sub-steps:
1. Disconnect the battery to ensure safety.
2. Remove the serpentine belt by loosening the tensioner.
3. Disconnect the electrical connector and refrigerant lines from the AC compressor.
4. Unbolt the compressor from the mounting bracket and remove it from the engine bay.
5. Install the new compressor, ensuring to add the correct amount of refrigerant oil.
6. Reconnect the refrigerant lines and electrical connector.

4. Replace Cabin Air Filter (if necessary)

Tools Required: Screwdriver (if applicable).
Sub-steps:
1. Locate the cabin air filter compartment (usually behind the glove box).
2. Remove the glove box or access cover to reach the filter.
3. Remove the old cabin air filter and install a new one.
4. Reassemble the glove box or cover.
