Driver Door Power Window Master Switch 🪟

This is the main control unit on the driver’s door that commands all electric windows and the window lock. It restores factory feel to the buttons, fixes dead spots, and brings back smooth auto-down/auto-up where equipped. Built to OE spec, it snaps into the door trim and plugs into the original harness for a clean, no-hack repair.

Why this part is needed

Daily use wears contacts and sliders. Dust, heat, and moisture oxidize terminals. When that happens, windows become slow, intermittent, or stop responding. A fresh switch keeps your cabin secure, improves convenience, and prevents motor overloads.

How it works

Each button routes low-voltage signals to the window motor circuits. The board inside uses spring contacts and tracks to reverse motor polarity for up/down operation. The child lock disables passenger door switches. Auto functions use a detent and internal logic to complete a full stroke. 🔧

What if it breaks

Windows may be stuck open or closed, only work from some doors, or drain the battery due to shorted contacts. You can lose auto function, melt a connector from arcing, or fail inspection in rainy climates. Replace at first sign of heat, burning smell, or inconsistent clicks. ⚠️
