GM Power Window Switch Wiring Diagram
A General Motors (GM) power window switch wiring diagram can vary depending on the model and year of the vehicle. However, I can provide a general guide on how a typical GM power window switch might be wired. Please note that this is a simplified version and may not exactly match all GM models.
Typical GM Power Window Switch Wiring:
-
12V Power Source: One of the pins will be connected to a 12V power source, usually routed through the car's fuse box.
-
Ground Connection: Another pin serves as the ground.
-
Window Motor Control Pins: There will be pins dedicated to controlling the window motor. Typically, these include:
- Up Control: When activated, sends power to the window motor in one polarity, causing the window to move up.
- Down Control: Activates the window motor in the reverse polarity, moving the window down.
-
Illumination (if available): Some switches have backlighting for visibility at night. If present, there will be a pin for this feature.
-
Master Control (if applicable): In case of a master switch (usually on the driver's side), there may be additional pins for controlling the passenger windows.

Important Notes:
- Vehicle Specific Diagram: It is crucial to get a wiring diagram specific to your GM model and year, as the wiring can significantly vary between different models and years.
- Safety Precautions: Always disconnect the battery before working on electrical components to avoid the risk of shock or accidental short circuits.
- Consult a Professional: If you are unsure or not comfortable with electrical work, it is advisable to consult a professional mechanic or auto electrician.
You can often find vehicle-specific wiring diagrams in the vehicle's service manual or through online automotive repair resources. If you provide the specific model and year of the GM vehicle, I could give more detailed information or guide you on where to find the exact wiring diagram.
