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.
Unplug the wiring harness from the window motor. You will have to press down on the clip that holds the wiring harness into place and pull the harness out. These can be hard to press and sometimes it is best if you can get a screwdriver on it to press it in. Unbolt the harness andor motor from the door's interior. Any bolts holding the harness and motor will have to be removed.
