Front Left Driver Electric Seat Adjust Control Switch Assembly OEM Number 1098529 Compatible With Tesla Model 3 / Model Y Power Seat Adjustment Spare Parts

Product Appearance Description

This front left driver power seat adjustment switch matches passenger seat switch 1098530 as a pair for Tesla Model 3 / Model Y. It adopts long matte black integrated ABS injection molding, three OEM screw fixing lugs reserved on housing to lock firmly on left driver seat outer plastic trim. A large anti-slip rotary knob at upper section controls lumbar support inflation and deflation. Multiple independent silent vertical buttons under the knob realize multi-direction electric adjustment: seat slide, cushion height, backrest tilt. Integral positioning buckles around shell fit original seat side mounting slots precisely. A dedicated multi-pin wiring socket with thickened anti-oxidation copper pins on rear resists oxidation and poor contact under long-term leg touch and dust accumulation. Fully sealed waterproof and dustproof internal structure protects circuit board from water stain and dust corrosion. It is 1:1 OEM molded, no trimming of seat interior plastic parts required during installation and removal.

Product Function Description

It is fully compatible with original 12V body electronic control system of Tesla Model 3 and Model Y, full-range electric adjustment control for driver seat, core functions as follows:

1.Two-way rotary knob adjustment: driver seat lumbar support inflate (tighten) / deflate (relax);

2.Zoned vertical function buttons: full seat slide forward/backward, cushion height lift/lower, backrest tilt forward/recline backward;

3.Built-in electromagnetic shielding anti-interference chip, no current noise during seat motor operation, instant response for adjustment command without delay;

4.Dual over-current & short-circuit protection chips on circuit board cut off power automatically under circuit short circuit and motor overload to protect seat control module;

5.Fully compatible with factory CAN communication protocol, works normally after direct harness plug-in, no ECU coding at repair shop needed.
It is a direct replacement for faulty original seat switch assembly with unresponsive buttons, stuck lumbar knob, failed multi-direction seat adjustment and oxidized pins.
