Single Door Window Control Switch Assembly With Noise Reduction Fabric Wire Harness OEM Number 30172172 Compatible With Tesla Model 3 Model Y Passenger Rear Door Window Lift Spare Parts

Product Appearance Description

This single door auxiliary window switch is equipped with full fabric noise reduction wiring harness, featured with exclusive brown plastic base, which distinguishes it from OEM 30172170 version with black base. It is designed for front passenger and rear doors of Tesla Model 3 / Model Y. A slim matte black single lift button with embedded thin backlight indicator line is arranged on front for clear operation at night without extra interior light. The rear of the button connects to a black wear-resistant fabric wrapped wire harness, whose fabric layer isolates vibration noise and shields electromagnetic clutter. A factory-matched green multi-pin connector with thickened anti-oxidation copper pins is equipped at wire terminal, avoiding overheating and poor contact after long-time power-on. Integrated side mounting clips enable clip-on installation into door panel slots without damage. The sealed dustproof and splash-proof shell protects internal circuit board from door moisture and dust, 1:1 OEM molded to fit original car interior without trimming plastic during installation and removal.

Product Function Description

It is fully compatible with the original 12V body electronic control system of Tesla Model 3 and Model Y, specially developed for single window control of passenger and rear doors. Core practical functions:

1.Single button independently controls up and down movement of the matching window, freely adjust arbitrary opening height of window;

Built-in soft backlight indicator on button surface for high recognition during night driving operation;

2.Outer fabric wrapped wire harness has dual functions of vibration reduction and signal shielding, eliminating current noise during window lifting and stabilizing signal transmission;

3.Dual over-current & short-circuit protection chips integrated on circuit board to effectively prevent original vehicle body control module damage caused by circuit overload;

4.Fully compatible with factory vehicle communication protocol, plug the green connector into original wiring directly, no ECU coding at repair shop required.
It can directly replace faulty original rear / passenger window switch assembly with unresponsive buttons, dead backlight, aged broken wire harness, stuck window lifting and cracked base.
