Tesla Model 3 and Model Y Seat Adjustment Button — Restore a Controllable Driving Position
This seat adjustment button for the Tesla Model 3 and Model Y (2020-2023) replaces the electric control module for the front driver or passenger seat, part number 1551854-01-A on the left side and 1551855-01-A on the right side. When a single adjustment direction stops responding — forward, backward, backrest tilt, or seat height — the failure almost always stems from this switch block, not the seat motor.
A Design Tailored for Your Tesla Model 3 and Model Y
The module retains the exact geometry of the Tesla part: the same mounting plate, the same screw holes, and the same control levers. It installs behind the original seat cover without any modification, and the adjustment paddles regain their precise travel. Two versions are available depending on the model year and side of the vehicle: with a round lumbar adjustment dial, or in a simplified version without a dial.
Technology, Quality & Finish
The microswitches are new, mounted on a rigid printed circuit board, and protected by a technical polymer housing. The plated contacts resist oxidation and vibration, two common causes of progressive failure in power seat controls. The connector follows the manufacturer's pinout, preserving communication with the seat control unit and the stored positions.
Installation, Compatibility & Durability
Replacement requires removing the seat side cover, unscrewing the old module, reconnecting the connector, and reassembling — allow about thirty minutes, with no coding required. Compatible with Tesla Model 3 and Model Y models from 2020 to 2023, depending on the version. As the two versions are visually very similar, be sure to compare your removed part with the photos and the engraved part number before choosing your variant.
