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

Solution

1. Preparation

• Tools Required: OBD-II scanner, AC manifold gauge set, basic hand tools, flashlight.
• Ensure the vehicle is parked on a level surface and the engine is off before starting the repair.

2. Recharge the AC System

• Sub-step 1: Connect the AC manifold gauge set to the low and high-pressure service ports.
• Sub-step 2: Check the refrigerant levels. If low, proceed to recharge the system with the appropriate refrigerant (typically R-134a for older models or R-1234yf for newer models).
• Sub-step 3: Follow the manufacturer's specifications for the amount of refrigerant to add. Use a scale if necessary to ensure accurate measurement.

3. Repair or Replace Components

• Sub-step 1: If the compressor is not engaging, check the electrical connections and fuses. Repair any damaged wiring or replace blown fuses.
• Sub-step 2: If a leak is detected in any AC components, replace the affected components (e.g., hoses, O-rings, or the compressor).
• Sub-step 3: If the cabin air filter is clogged, remove and replace it with a new one.

4. Final System Check

• Sub-step 1: After repairs, run the AC system to monitor for proper operation.
• Sub-step 2: Check the pressures on the manifold gauge again to ensure they are within the manufacturer’s specifications.
• Sub-step 3: Inspect for any refrigerant leaks using a UV dye or electronic leak detector.
