why is my Tesla Model S AC blowing hot air

Solution

1. Preparation

• Gather necessary tools and materials.
• Ensure the vehicle is parked on a level surface and turned off.
• Disconnect the vehicle from any power source (if applicable).

2. Check Refrigerant Level

• Locate the service port for the AC system.
• Use a refrigerant gauge to check the pressure; ensure it meets specifications.
• If low, evacuate the system and recharge with the correct type and amount of refrigerant (R134a or R1234yf, depending on the model year).

3. Inspect and Test AC Compressor

• Visually inspect the AC compressor for any signs of leaks or damage.
• Start the vehicle and turn on the AC to check if the compressor engages.
• If it does not engage, test the electrical connections and the compressor relay.

4. Clean or Replace Cabin Air Filter

• Open the glove box and remove it to access the cabin air filter compartment.
• Remove the old filter and inspect it for dirt and blockages.
• If clogged, clean it or replace it with a new cabin air filter.

5. Inspect AC Condenser

• Check the AC condenser for any debris, dirt, or physical damage.
• Clean the condenser with low-pressure air or a gentle wash to remove any accumulated dirt.

6. Verify Climate Control System Functionality

• Once repairs are made, turn on the vehicle and the AC system.
• Monitor the touchscreen for any error codes or warnings.
• Check if the AC is now blowing cold air properly.
