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

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the negative battery terminal to ensure safety during repairs.

2. Refill Refrigerant

• Tools Required: AC manifold gauge set, refrigerant canister
• Use the pressure gauge to check the low and high-pressure sides of the AC system.
• If levels are low, connect the refrigerant canister to the low-pressure port.
• Slowly add refrigerant according to the manufacturer's specifications (typically R-134a or R-1234yf).
• Monitor the pressure gauge to avoid overfilling, aiming for the specified pressure range.

3. Inspect and Replace the Cabin Air Filter

• Tools Required: Screwdriver (if necessary for access)
• Locate the cabin air filter housing, usually behind the glove box.
• Remove the glove box or cover to access the filter.
• Take out the old filter, noting its orientation, and install the new filter in the same orientation.

4. Inspect and Test AC Compressor

• Tools Required: Multimeter
• Locate the AC compressor and visually inspect for damage or leaks.
• Use a multimeter to test the compressor clutch coil for continuity.
• If faulty, proceed to replace the compressor following proper removal and installation procedures.

5. Check AC System Electrical Components

• Tools Required: Multimeter
• Inspect the AC fuse and relay in the fuse box; replace if blown.
• Check the wiring and connections to the AC compressor for damage or corrosion.
