Tesla Model S

Window Regulator Repair

SKU: 44-TES-MS-BUSH Categories: , , Tags: , , ,

The Tesla Model S window regulators are one of the more frequent failure points.  This part replaces the most failure prone component in this assembly, replacing a plastic part with a far more durable Billet Aluminum slotted bushing.

The slotted feature allows for field retrofit without removing and re-crimping the steel cable in the assembly.

Typical failure symptoms indicating a broken spring loaded bushing are:

  • Sluggish window operation
  • Widow is stuck in open, closed, or in between
  • Window closes but opens again on its own


The old broken plastic bushing will need to be removed.  We find a pair of diagonal cutters are ideal for this procedure.  Just nibble around the plastic remnants, and slide in the Billet Aluminum replacement.

This is what is inside the door

These window regulators are manufactured for Tesla, not by Tesla.

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.

 

 

Where does the break occur?

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.

 

 

 

Our aftermarket bushing

The billet aluminum version created in our machine shop provides the durability necessary for a part like this, in this application.

Replacement requires removal of the inside door panel, and removal of the window regulator assembly.

The old broken plastic bushing will need to be removed.  We find a pair of diagonal cutters are ideal for this procedure.  Just nibble around the plastic remnants as shown in our YouTube instructional video, and slide in the Billet Aluminum replacement.
