These window regulators are manufactured for Tesla, not by Tesla. We take the stock version and improve the design.
Essentially, it is a pulley system device fed by a DC motor, that closes and retracts the side windows in a Tesla fed by LIN signals from the door control modules, and actuated by buttons on the door.
The problem is in an under-designed spring loaded shock absorber at extreme limits, and consists of a plastic bushing. This plastic part snaps with age and use, and removes the tension in the pulley system, rendering the window regulator unusable.
To the right is an example of a compromised plastic bushing.
A combination of material weakness, age, and heat, tend to predictably split this plastic bushing.
We replace the stock plastic bushings with aircraft grade billet aluminum ferrules created in our machine shop, which provides the durability necessary for a part like this, in this application.
Replacement of the requires removal of the inside door panel, and removal of the window regulator assembly.
