Early 1.5-series Roadsters use a dedicated high-voltage electric A/C compressor to provide cabin cooling. This compact compressor is driven directly from the traction pack and is critical to both driver comfort and effective defog/defrost performance. With age, these units can become noisy, lose capacity, or develop insulation faults that disable the A/C system.
The unit offered here is the correct high-voltage A/C compressor for Tesla Roadster 1.5 cars, built around the Sierra variable-speed rotary/scroll platform used in OEM EV applications. It is configured for the Roadsterโs R134a system and high-temp A/C duty, with the proper suction and discharge fittings for a direct bolt-in replacement. Not for 2.0 / 2.5 Roadsters, which use a different compressor configuration.
