8 Pin Power Window Switch Wiring Diagram

Posted on

If you’re looking to install or replace an 8 pin power window switch in your vehicle, there are some important details you need to know before getting started. An 8 pin power window switch is used to control the electric windows on a car or truck. In order to wire an 8 pin power window switch, you need to understand what each pin does and the proper color codes for the wires. You also need to be aware of any common issues with 8 pin power window switches and know how to troubleshoot a faulty switch.

How Do I Wire an 8 Pin Power Window Switch?

Wiring an 8 pin power window switch is relatively straight forward. First, you will need to identify the function of each pin in the switch. Generally, most 8 pin power window switches have two pins assigned to power, two pins assigned to ground, and four pins assigned to the driver side and passenger side window motors. The colors of the wires used for the power and ground pins can vary from manufacturer to manufacturer, but they are typically either black or red for power, and green or yellow for ground. The remaining four pins should be color coded to indicate which window motor they belong to. Once you have identified which pin does what, you can connect the appropriate wires to the switch.

What Are the Common Issues With 8 Pin Power Window Switches?

Common issues with 8 pin power window switches usually come down to poor wiring or a faulty switch. The most common issue occurs when the power or ground pins are not connected properly. This can cause the window motors to malfunction or stop working altogether. Another issue is corrosion, which can occur from water damage or poor wiring. Lastly, a faulty switch can cause window motors to malfunction or even prevent the window from moving at all.

How Do I Troubleshoot a Faulty 8 Pin Power Window Switch?

Troubleshooting a faulty 8 pin power window switch can be done by using a multimeter to check if there is electricity going through the wires. Start by disconnecting each wire from the switch and set the multimeter to measure voltage. If the multimeter reads 0 volts, then that indicates a bad connection which should be replaced. If the multimeter reads higher than 0 volts, then that indicates the switch is sending electricity and the problem lies elsewhere. In this case, you may need to check the window motors for any issues.

Can I Replace an 8 Pin Power Window Switch With a Toggle Switch?

In most cases, you cannot replace an 8 pin power window switch with a toggle switch. While it is possible to do so, it would require additional wiring and components. An 8 pin power window switch is designed to work specifically with the electric window motors and its necessary circuitry. Trying to use a toggle switch without the correct wiring and components could result in damage to the motor and window system.

What Is the Cost of an 8 Pin Power Window Switch?

The cost of an 8 pin power window switch will vary depending on the make and model of your vehicle. Generally speaking, an 8 pin power window switch should cost anywhere between $20 to $50. However, some specialty switches can cost up to $100 or more.

Where Can I Buy an 8 Pin Power Window Switch?

You can purchase an 8 pin power window switch from most auto parts stores or online retailers. Before buying one, make sure to double check the make and model of your vehicle to ensure that you get the right switch. Online retailers such as Amazon or eBay often carry a wide selection of switches at varying prices so you can compare and find the best price.

Installing or replacing an 8 pin power window switch can be a bit intimidating, but it doesn’t have to be. As long as you know the functions of each pin, the proper color codes for the wires, and how to troubleshoot a faulty switch, you should be able to do the job with ease. Understanding the cost and where to buy an 8 pin power window switch is also important so you can plan ahead and get the right switch for your vehicle.
