why does my Porsche 911 992 (2019-Present) AC blow warm air

Solution

1. Preparation

• Gather tools and parts.
• Disconnect the vehicle's battery to ensure safety.
• Make sure the vehicle is parked on a level surface.

2. Recharge Refrigerant

• Tools Required: Manifold gauge set, refrigerant can.
• Connect the low-pressure side of the manifold gauge to the AC service port.
• With the engine running and AC on max, check the refrigerant level; if low, recharge to the manufacturer’s specifications.
• Monitor the pressure and ensure it is within the normal range (approximately 30-40 PSI for low side when running).

3. Inspect and Replace AC Compressor

• Tools Required: Socket set, torque wrench, refrigerant recovery machine.
• Locate the AC compressor and inspect for signs of wear or failure.
• Remove the drive belt from the AC compressor.
• Disconnect electrical connectors and refrigerant lines (ensure refrigerant is recovered properly).
• Remove mounting bolts and take out the old compressor.
• Install the new compressor, ensuring all bolts are torqued to specifications.

4. Replace Cabin Air Filter

• Tools Required: None (hand tools may be needed).
• Locate the cabin air filter housing (usually behind the glove compartment).
• Remove the filter cover and replace the old filter with a new one, ensuring proper orientation.
• Reassemble the filter housing.

5. Testing System Functionality

• Reconnect the battery and start the engine.
• Turn on the AC system and monitor for cold air.
• Check for any unusual noises from the compressor.
