How to Diagnose and Resolve

  1. 1 Check if the cabin A/C is functioning — the chiller is shared between cabin and battery cooling
  2. 2 Schedule a Tesla Service appointment — chiller issues typically require professional refrigerant handling
  3. 3 Avoid DC fast charging in extreme temperatures until repaired
  4. 4 Technician will perform HVAC diagnostics and refrigerant pressure test
  5. 5 Chiller replacement is a common Tesla repair
