2. What does a power window relay do?
A power window relay is responsible for taking a small current from the switch and using it to energize the relay. This allows a larger current to flow to the window motor without overheating the switch. The relay acts as a bridge between the switch and the motor, ensuring proper power distribution.

The cost of fixing a power window relay can vary depending on the specific vehicle and the labor rates in your area. On average, the cost for a window switch replacement can range from $307 to $348. This includes both the labor and parts.
4. Do electric windows have a relay?
Yes, electric windows typically have a relay in their circuit. The relay is connected to the battery and the window switch, allowing the switch to control the flow of power to the window motor. This relay helps protect the switch from handling the larger current required by the motor.
5. What happens when a power relay fails?
When a power relay fails, it cuts off power to the component it controls. In the case of a power relay for a window, if it fails, the window will not receive power and will not be able to open or close.

Power relays can fail due to mechanical wear and tear, such as worn-out contacts or a failed actuator. Environmental factors like temperature, humidity, vibration, and dust can also contribute to relay failure.
7. What causes a power window switch to go bad?
A power window switch can go bad due to several reasons, including wiring issues, physical damage, or simply wear and tear from regular use. Over time, the buttons on the switch can wear out, leading to failure.
8. Does each power window have its own switch?
In most cases, each power window has its own individual switch. Additionally, there is usually a set of switches located on the driver's door or the A-frame pillar, allowing the driver to operate all the windows.
9. Why would an electric window stop working?
There are various reasons why an electric window may stop working. It could be due to blown fuses that prevent the electrical controls from functioning, accidental engagement of the child safety lock, or a malfunctioning window motor despite the window switch working correctly.
