Front Left Master Tesla Window Switch for Model S/X (1028641-00-A 1003589-00-B)

Tesla Window Switch – Front Left Master Replacement

This Tesla window switch is designed as a direct replacement for the Front Left Master (Driver Side) unit found in:

• Model S 2012–2020
• Model X 2016–2020

Matching OE 1028641-00-A and 1003589-00-B, this switch restores proper window operation and factory-level responsiveness. If your original switch is worn, peeling, sticking, or intermittently failing, replacing only the master control unit is a practical and cost-effective solution.

Engineered to meet OEM specifications, it installs directly into the original door panel mounting position and connects to the factory wiring harness without modification.

✅Common Problems with the Factory Tesla Window Switch

Tesla owners frequently experience the following issues with OE 1028641-00-A / 1003589-00-B units:
