how to fix the air conditioning in my Porsche 911 992 (2019-Present) that's blowing warm air

Solution

1. Preparation

• Tools Required: OBD-II scanner, refrigerant gauge set, multimeter, socket set, safety glasses, gloves.
• Safety Warning: Disconnect the battery before working on electrical systems. Ensure the engine is cool before starting any repairs.

2. Check and Recharge Refrigerant

1. Connect Refrigerant Gauge: Attach the low and high-pressure gauges to the AC service ports.
2. Read Pressure Levels: Compare the readings to the manufacturer's specifications.
   • If pressure is low, proceed to recharge; if within range, further diagnostics are needed.
3. Recharge System: If low, add the appropriate refrigerant (usually R134a or R1234yf for newer models) until proper levels are achieved.
4. Monitor for Leaks: After recharging, watch for any immediate drop in pressure which indicates a leak.

3. Inspect and Replace AC Compressor

1. Remove the AC Compressor:
   • Disconnect the electrical connector from the compressor.
   • Remove the mounting bolts using a socket set.
   • Disconnect the refrigerant lines (be cautious of remaining refrigerant).
2. Install New Compressor:
   • Position the new compressor in place and secure it with bolts.
   • Reconnect the refrigerant lines and ensure they are tight.
   • Reattach the electrical connector.
3. Evacuate and Recharge System Again: Use a vacuum pump to evacuate the system for at least 30 minutes, then recharge with refrigerant.

4. Replace Cabin Air Filter

1. Access Cabin Filter: Locate the filter housing (usually behind the glove compartment).
2. Remove Old Filter: Take out the old filter and inspect for dirt and debris.
3. Install New Filter: Insert a new cabin air filter, ensuring it is oriented correctly.
