Tesla Roadster

400 V HVAC Controller Rebuild

This sub-assembly resides under to hood on a Tesla Roadster, and controls the AC and Heater devices. It was originally made by Eberspächer UK.

It is also part of the Roadster pre-charge interlock loop, and when it fails, it will shut down the Roadster, cause isolation issues, or bsm error alerts, and can prevent the Roadster from charging.

This part has been out of production for many years. Tesla may have dwindling supply left. Spares are often harvested from donor Roadsters, the supply of which is also steadily declining. Even if a replacement is found, they have aged and are most likely full of deferred maintenance issues.

Fortunately, this part is quite rebuildable. We have successfully reverse engineered this part, and are offering full rebuild services which include resolving engineering problems, and improving the original design.
