PTC Heater Assembly

PTC Air Heater Core — 6007385-00-E

Early Tesla Model S vehicles use a high-voltage PTC (Positive Temperature Coefficient) air heater rather than a coolant-based heater core. Mounted inside the HVAC box ahead of the firewall, this unit converts pack power directly into warm air for rapid cabin heating and defog/defrost performance.

The part offered here is the genuine Tesla Model S PTC Air Heater Core, Tesla P/N 6007385-00-E (and superseding revisions in the 6007385-00-x family) for Model S Feb 2012 – Mar 2016. It is the correct direct-fit replacement for pre-facelift cars that have lost cabin heat, show PTC-related HVAC faults, or have a failed high-voltage isolation check.

• OEM PTC heater core — Tesla-branded 6007385-00-E unit for factory fit and performance.
• High-voltage cabin heat — uses the traction pack to provide fast electric heating with no coolant loop warm-up delay.
• Correct pre-facelift fitment — designed for 2012–2016 Model S HVAC housings and wiring; not the later GEN3 heater (P/N 1060432-00-E).
• Common failure remedy — resolves “no cabin heat” complaints caused by open-circuit heater elements or internal insulation faults.
• Drop-in replacement — reuses the existing HVAC case; no software changes typically required when replacing like-for-like part numbers.
