my Porsche 911 992 (2019-Present) AC is blowing warm air what should I do

Solution

1. Preparation

• Gather tools and parts.
• Disconnect the battery to ensure safety.

Tools Required:

• OBD-II scanner
• Manifold gauge set
• Socket set
• Screwdriver set
• Multimeter

2. Check and Recharge Refrigerant

1. Connect the manifold gauge set to the AC service ports (high and low).
2. Check the pressure readings. If the pressures are low, proceed to recharge the system.
3. Use an appropriate refrigerant (R134a or R1234yf based on model specifications) and fill to the required level.
4. Monitor the system for any changes in pressure after charging.

3. Inspect and Replace AC Compressor (if necessary)

1. If the compressor is not engaging, test it with a multimeter to check for electrical faults.
2. If faulty, remove the serpentine belt and disconnect the compressor.
3. Unbolt the compressor from the mounting bracket and remove it from the engine bay.
4. Install the new compressor, ensuring that all O-rings and seals are replaced.
5. Reconnect the compressor and attach the serpentine belt, ensuring proper tension.

4. Replace AC Relay/Fuse (if necessary)

1. Locate the fuse box and identify the AC relay and fuse.
2. Inspect the fuse for continuity using a multimeter; replace if blown.
3. Replace the relay if it is not functioning properly.
