System Testing

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2020 Tesla Model S, 2019 Tesla Model S, 2018 Tesla Model S, 2017 Tesla Model S, and 2016 Tesla Model S. However, it is still accessible from the selected car via links, so may be relevant.

On the touchscreen, set the temperature to LO on both the driver and passenger controls.
Run the A/C system for 10 minutes to allow the dye to circulate.
Using an ultraviolet (UV) or blue light, examine all A/C lines for leaks.
NOTE: Leaks glow a bright yellow-green.
Once the leak is located, recover refrigerant from the vehicle, refer to A/C Refrigerant Recovery And Recharge (Remove And Replace) .
Replace the defective component(s).
NOTE: Also replace the desiccant bag, as the A/C system has experienced a leak. See Receiver Dryer And Desiccant (Remove And Replace) .
Recharge the vehicle with refrigerant, refer to A/C Refrigerant Recovery And Recharge (Remove And Replace) .
CAUTION: If a component was replaced, additional oil must be added to the system. See the end of the "Recover Refrigerant and Verify Charge" section for more information.
Use a general-purpose cleaner to clean off all dye residue. This prevents leftover residue from being mistake for a leak in future repairs. Confirm that all residue is removed by inspecting all A/C lines with a UV or blue light.
Run the A/C system with the temperature set to LO . Inspect all A/C lines with a UV or blue light to verify repairs.
Fill out the Tracerline dye label and place it next to the A/C refrigerant label on the right underhood apron to inform future technicians that dye has been added to the A/C system.
Reinstall all components that were removed for access.
