my Porsche 911 992 (2019-Present) AC is blowing warm air how to fix

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the vehicle's battery to ensure safety.
• Allow the engine to cool down before working on the AC system.

2. Check and Recharge Refrigerant

• Connect the manifold gauge set to the service ports of the AC system.
• Check the pressure readings; if low, proceed to recharge.
• Recover any remaining refrigerant if necessary.
• Using a refrigerant recovery machine, evacuate the system for at least 30 minutes.
• Recharge with the proper type and amount of refrigerant (R-134a or R-1234yf as specified by manufacturer).

3. Inspect and Replace Components

• AC Compressor:

  • If damaged, remove the AC compressor by disconnecting the electrical connector and the refrigerant lines (ensure recovery of refrigerant).
  • Unbolt the compressor from the engine mount and replace with a new compressor.

• Cabin Air Filter:

  • Locate the cabin air filter compartment (usually behind the glove box).
  • Remove the old filter and install a new one.

4. Reassemble and Test

• Reconnect all components, ensuring all bolts are torqued to the manufacturer’s specifications.
• Reconnect the battery.
• Start the vehicle and turn on the AC to the maximum setting.
• Monitor the system for operation and check for cold air at the vents.
