how to fix the AC not blowing cold air in Tesla Outback 6th Generation (2020-2024)

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, manifold gauge set, basic hand tools, and safety gloves.
• Ensure the vehicle is parked on a level surface and the engine is turned off.
• Disconnect the battery to prevent electrical shorts.

2. Recharge Refrigerant

• Check Refrigerant Level:

  • Connect the low and high-pressure sides of the manifold gauge set to the AC service ports.
  • Start the vehicle and turn the AC to maximum cool.
  • Read the pressure on the gauges; if low, proceed to recharge.

• Recharge the System:

  • Locate the refrigerant can and attach it to the manifold gauge set.
  • Open the low-pressure valve and allow refrigerant to flow into the system until the correct pressure is reached (typically 30-40 psi on the low side).
  • Close the valve and disconnect the refrigerant can.

3. Inspect and Replace Components

• Inspect the AC Compressor:

  • If the compressor is not engaging, check the fuse related to the AC system and replace it if blown.
  • If the compressor is faulty, disconnect power and replace it following manufacturer specifications.

• Replace the Cabin Air Filter:

  • Locate the cabin air filter access panel, typically behind the glove compartment.
  • Remove the old filter and install a new one, ensuring the airflow direction is correct.

4. System Leak Check

• Perform a Leak Test:
  • Use a UV dye and add it to the AC system.
  • Run the AC for about 10 minutes, then inspect for leaks using a UV light.

5. Final Assembly

• Reconnect the battery.
• Ensure all components are securely fastened and hoses are properly connected.
