Attach the leads of the multi-meter to where the electrical wires come into the motor. Again, set it to DC volts and it should read 12 volts. Look for any interrupted voltage caused by a loose connector or corrosion. If there are any loose or corroded connections in the circuit they will disrupt the signal and cause your window to malfunction. Fix the connector or corroded areas. Push any connectors or wiring harnesses together tightly, and clean any corrosion away with a wire brush or similar tool. Test the window again. If your problem was in the circuitry and is now fixed, then your window should freely roll up and down without any restrictions or delays.
If you have electric (power) windows in your car, there may come a time that you push the button and the window doesn't respond the way it used to. If the window suddenly stops moving at all, the problem could be as simple as a blown fuse or a loose connection. It is also possible that you have a faulty switch, especially if the window works on a hit and miss basis. Window motors go down sometimes as well. This is usually characterized by a gradual decrease in how well the window responds to the switch, but a slow window could also be getting stuck on the gaskets. Once you identify the problem, you may be able to repair it with some basic tools.
