Automatic side window not working

ANSWER : If removing the driver door window switch (or the driver-side console switch), and applying direct power to the harness yields successful operation of the window, the problem is the switch that was removed for the test. This can be confirmed utilizing a voltmeter/multimeter, and following the "power path" from the fuse, to the switch, to the output side of the switch (harness plug side of the switch), etc. A YourMechanic technician can assist with the diagnosis of your window issue and help you fix it accordingly.

ANSWER : Hi there. Usually when both window switches do not work it is due to an electrical fault with the primary control module. There is a center module that relays all electricity from switches to individual window drive motors to open and close. When more than one switch doesn’t appear to be working, it typically due to an issue with that center window control module or electrical relay powering the system. It would be a good idea to have a professional mechanic come to your location and complete a window not working inspection to determine precisely what is causing this issue before attempting any further repairs.

ANSWER : Hello, thank you for writing in. There are a few considerations we need to make during this process. One being the battery is responsible for providing power in the accessory mode, while the alternator provides the power while the vehicle is on. Secondly, when only one window is effected, it is typically the regulator or the motor that is to blame, rather than a switch issue. However we can test for the available power to the switch in both situations, to find out if there is an honest power drop while the vehicle is running, or if the issue is with how the motor is using the power. If the power supply to the motor is low when the vehicle is running, you will have to trace down what is causing low power. You will want to focus on the alternator, and trace the circuit to the switch checking after each component. For more help, contact our service department to schedule an appointment.

ANSWER : Hi there. It’s possible that an electrical relay is damaged or you have a shorted electrical wire or faulty ground wire that is causing this issue with your motor. It’s also possible that a mechanical arm inside the passenger side door is bent. Before you start replacing more parts, it’s probably a better idea to have a professional mechanic complete a power window not working inspection, so they can pinpoint the source and recommend the right repairs.

ANSWER : Hi there, this issue generally comes up often when we see a power window that does not work on the passenger switch, but still works with the driver’s master switch. It means that the passenger side window switch has failed. The fact that the drivers switch operates the window properly lets you know that the window components all function properly as that the problem is probably electrical.

A technician that is diagnosing this would use the wiring diagram to find the proper wires to test and check for power when the window is rolled up to see if there is power present when the window is commanded to roll down with the switch. Given that you are still under warranty, this scenario should be something the dealership would resolve free of charge as part of the warranty. If the vehicle is only under powertrain warranty and not the full warranty, the technicians at YourMechanic are able to provide diagnosis for your window and can perform a power window switch replacement for you if necessary.

ANSWER : Hello. There are several things that can cause this. It can be caused by a bad ground connection or an issue with the circuit breaker that supplies power to this circuit. You would need to used a voltage meter to check the supply voltage. If there is voltage to the switch then the ground need to be checked. If the ground is also fine then you may have a wiring issue or a bad motor at each window which can occur over time.

ANSWER : A technician with an advanced scan tool can verify the issue. The mirror system is complex and involves many modules. The Body Control Module is a possible cause, but it’s doubtful; replacement requires reprogramming, which requires special equipment. I would check the driver’s and passenger’s door modules; toggle or move the switch on the driver’s side to see if it causes the problem, and ensure that the mirror glass itself is not loose on the passenger’s side mirror assembly.

Without diagnosing the problem with advanced equipment, the issue is hard to diagnose. A qualified YourMechanic technician can show up to the location of your vehicle with a scan tool to inspect and diagnose your power mirror issue.

ANSWER : The switch internals of one or both switches are faulty or there is a bad connection to the switches. To resolve this, the switches have to be removed from the door so that you can get access to the terminals. From there it is a simple matter of testing for switch continuity or power on the right terminals when the switch is supposed to be commanding up or down operation. Any switch not working as intended is condemned and replaced.
