1. First, open the door and roll down the window.
2. Next, disconnect the negative battery cable.
3. Then, remove the door panel and inner weather-strip seal.
4. Next, remove the power window regulator bolts.
5. After that, remove the motor from the bracket and unplug it from the wiring harness.
6. Finally, test the motor by reversing the polarity of the wires and applying 12 volts to it.
- To test a window motor, you will need a voltmeter and an assistant
- Have your assistant hold the window up while you disconnect the negative battery terminal
- Remove the door panel and locate the window motor
- Test for continuity between the two terminals on the motor with your voltmeter
- If there is no continuity, then the motor is bad and will need to be replaced
- Reconnect the negative battery terminal and test the window again with your assistant’s help
- If it still does not work, then the problem may lie in the wiring or switches and will require further diagnosis
Symptoms of Bad Window Motor
If your car’s window motor isn’t working properly, there are a few things you can look for to diagnose the issue. Here are some common symptoms of a bad window motor:
1. The window moves slowly or not at all when you try to operate it.
2. You hear a grinding noise when you try to operate the window.
3. The window feels “jumpy” or “jerky” when you try to move it up or down.
4. The window gets stuck in one position and won’t move at all.
If you’re experiencing any of these symptoms, it’s likely that your window motor is failing and will need to be replaced. Fortunately, this is a relatively easy repair that can be done by most do-it-yourselfers with just a few tools.
How to Test a Power Window Motor With a Battery
If you have a power window motor that isn’t working, you can test it with a battery. First, disconnect the motor from the window. Then, connect one lead of your battery to the positive terminal on the motor, and the other lead to the negative terminal.
If the motor runs, then it’s working. If it doesn’t run, then you’ll need to replace it.
How to Test Window Motor With Power Probe
If your car’s power windows are not working, it may be due to a problem with the window motor. You can test the window motor to see if it is working properly using a power probe.
To test the window motor, first disconnect the negative battery cable.
Then remove the door panel to access the window motor. With the door panel removed, you will be able to see the wires that connect to the window motor.
Using your power probe, touch each of the two wires that connect to the window motor.
If there is continuity between these two wires, then this indicates that the window motor is working properly and does not need to be replaced.
Symptoms of Bad Window Switch
If your car’s window switch isn’t working properly, there are a few different symptoms you might notice. The most obvious symptom is that the window won’t move when you press the switch. This can be frustrating, especially if it’s hot or cold outside and you need to adjust the temperature in your car.
Another symptom of a bad window switch is that the window may move very slowly when you press the switch. This can also be frustrating, as it can take a long time to get the window where you want it. In some cases, the window may move erratically when you press the switch, making it hard to control.
If you’re having any of these issues with your car’s window switch, it’s best to take it to a mechanic or dealership so they can diagnose and fix the problem.
Replace Window Motor Or Regulator
If your power window is having issues going up and down, it may be time to replace the window motor or regulator. Although this is a fairly easy repair, it’s important to know which part is causing the problem. In this blog post, we’ll show you how to diagnose and replace a faulty window motor or regulator.
First, start by checking the fuse box for a blown fuse. If the fuse is blown, replace it with a new one and see if that solves the problem. If not, then move on to testing the window motor.
To do this, you’ll need a voltmeter.
With the car parked and turned off, disconnect the negative battery cable. Next, remove the door panel so you can access the window motor.
With the door panel removed, use your voltmeter to test for power at the two terminals on the window motor connector. If there is no power present, then the problem is most likely with the window switch or wiring harness.
If there is power present at the terminals, then gently try movingthe window up and down with your hands while someone else watchesthe voltmeter.

How Do I Know If My Power Window Motor is Bad?
If you have a power window that isn’t working, there are a few things you can check to see if the problem is with the motor. First, make sure that the window is fully closed and the switch is in the off position. Then, open the door panel and check to see if the motor is getting power.
If it’s not, then the problem is most likely with the fuse or relay. If it is getting power, then gently try to move the window up or down with your hand. If it moves easily, then the problem is probably with one of the pulleys or gears.
But if it’s very difficult to move or makes strange noises, then chances are that your power window motor is bad and will need to be replaced.
How Do I Know If I Need to Replace My Window Regulator Or Motor?
If your car’s window regulator or motor needs to be replaced, there are a few things you can look for. First, if your window is making noise when it’s being raised or lowered, that’s a good sign that something is wrong. Second, if your window moves slowly or unevenly, that’s another indication that the regulator or motor may need to be replaced.
Finally, if your window gets stuck in one position and won’t move at all, it’s likely that the window regulator or motor has failed and will need to be replaced. If you’re unsure whether or not your car needs a new window regulator or motor, it’s best to consult with a qualified automotive technician.
What Causes a Window Motor to Stop Working?
There are a few different reasons why a window motor might stop working. One possibility is that a fuse has blown or there is a problem with the electrical system. Another possibility is that the window regulator or tracks are damaged and need to be replaced.
In some cases, the problem may be as simple as dirty or corroded terminals which can be cleaned or replaced.
How Do You Test a Window Motor And Switch?
Assuming you are testing the window motor and switch to see if they are working correctly, you would first need to check the fuse. If the fuse is blown, then replace it and try again. If the fuse is not blown, then check the voltage at the window motor.
It should be around 12 volts. If there is no voltage, then check the wiring harness for any loose or broken wires.
If there is voltage at the window motor, then unplug the connector and use a multimeter to test for continuity between the two terminals on the connector.
There should be continuity. If there is no continuity, then replace the window motor.
If there is continuity, plug in the connector and test for voltage at one of the terminals on the switch while operating it.
There should be around 12 volts when operated in either direction (up or down). If there is no voltage or intermittent voltage, then replace switch.

Conclusion
Assuming you would like a summary of the blog post titled “How to Test Window Motor”:
The first thing you need to do is take off the door panel. You will need a screwdriver to remove the screws that are holding it in place.
Next, you will need to disconnect the wires from the window motor. Once you have done that, you can remove the window motor from the door.
To test the window motor, you will need to connect it to a power source.
Once it is connected, you should hear it running. If it doesn’t make any noise or if it sounds like it is struggling, then it is most likely not working properly and will need to be replaced.
