why does my Porsche 911 992 AC blow warm air when it's on

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent electrical shorts.

2. Inspect and Repair Leaks

• Tools Required: UV leak detection kit, refrigerant dye.
• Apply UV dye to the AC system and run the AC for 10-15 minutes.
• Use a UV light to check for any leaks in the system. If leaks are found, repair or replace the affected components.

3. Recharge the AC System

• Tools Required: AC refrigerant gauge set, refrigerant canister.
• Connect the low and high-pressure gauges to the AC service ports.
• If refrigerant levels are low, follow the manufacturer's specifications to recharge the system using the appropriate refrigerant type (R134a or R1234yf, depending on your vehicle).
• Monitor pressure readings to ensure they fall within the normal operating range.

4. Replace Cabin Air Filter

• Tools Required: Screwdriver set.
• Locate the cabin air filter housing, typically behind the glove box.
• Remove the housing cover and take out the old filter. Install a new filter, ensuring it is oriented correctly.

5. Test AC System

• Reconnect the battery and start the engine.
• Turn on the AC system and set it to the lowest temperature.
• Check that the AC compressor is engaging and monitor the temperature of the air coming from the vents.
