Motor Werke's Repair for Your Tesla Model 3's PTC Heater

As winter sets in, ensuring your Tesla Model 3 is ready to face the cold becomes paramount. At Motor Werke, we’ve recently enhanced the winter driving experience for a Tesla enthusiast by replacing their Tesla Model 3’s PTC heater.

Understanding The PTC Heater:

The Positive Temperature Coefficient (PTC) heater is crucial in keeping your cabin warm during chilly weather. The PTC heater is designed to replace the function of a car’s heater core. Heater cores transfer heat from your engine to the cabin of your vehicle by moving air through the heater core. As Teslas are not equipped with an internal combustion engine, the PTC heater warms the air up and allows it to be circulated through to the cabin. In our latest service, we delved into the ins and outs of this heating element, how it operates, and the root cause of failure.
