How does a window relay control the motor?
For this reason, a relay has almost always been used to control the motor. The basic motor operation is done by reversing the polarity of it’s power and ground input. It is here where a properly connected window motor makes the whole arrangement worthwhile and stable.
How does a computer controlled relay driver work?
A relay controller is a device that is used to control a bank of switches. A relay controller works by turning on and off magnetic coils under logic control. A computer controlled relay driver allows your computer to send simple commands to activate a switch or a group of switches.
How many amps does a power window relay use?
A power window system uses a DC motor to actuate the glass and open the door windows. The DC motor works in the nominal 2 to 5 Amp current range. For this reason, a relay has almost always been used to control the motor.
What do you need to know about power window switches?
Each power window switch is normally supplied a battery voltage signal (with the ignition switch on). The appropriate switch must be manually depressed for window operation. The master switch may allow the driver to depress a particular button for an extra second so that the window may fully retract with one touch.

Where is the master switch on a power window switch?
1. All the windows quit working 2. Only one window stops working 3. Window works from master switch only 4. Windows work sometimes The power window switch makes it easy to open and close the windows in your vehicle. The switches are located near each window, with a master panel on or near the driver’s door.
When do I need to replace my power switch?
If the windows are not working properly, not working at all, or only work from the master switch, you may need to replace the power window switch. 1. All the windows quit working 2. Only one window stops working 3. Window works from master switch only 4. Windows work sometimes
What kind of motor does a power window system use?
A power window system uses a DC motor to actuate the glass and open the door windows. The DC motor works in the nominal 2 to 5 Amp current range. For this reason, a relay has almost always been used to control the motor. The basic motor operation is done by reversing the polarity of it’s power and ground input.
How can I tell if my window motor is analog or digital?
With a digital volt meter, we can test to see if power reaches the window motor. If the power window motor has two wires, it is an analog system. We can back probe the connector at the motor, to detect if current flows when we press the switch.
How does a power window relay switch work?
In this setup, both wires are normally grounds until one relay is energized by the switch and powers the motor in one direction. Activate the other relay and the polarity is reversed, and the motor turns in the opposite direction.
Is the 87 pin connected to the window relay?
You are correct, however the wiring is intentional. If the window motor were hooked up to the 87 pin, then it wouldn’t switch to a ground when de-energized and the motor wouldn’t have a complete circuit. In this setup, both wires are normally grounds until one relay is energized by the switch and powers the motor in one direction.
Where do I cut the wire for the window relay?
Placing them here puts them in the large void under the arm rest so they’re out of the way and downstream of the factory switches, so you have power going directly to the window motor. Then I cut the wires in the harness going to the window motor.
How do you test a power window motor?
Then I cut the wires in the harness going to the window motor. All you need to watch for here is that you leave enough wire on the switch side to connect them to the relays and to make sure you have the same color wires going to the same relay. Last step was to connect the wires at the junction block and test the windows.
