Assuming that the battery is known to be good, then the next item to check is the battery terminals - the actual points at which the battery is connected into the electrical system. It is very important that these connections are clean and tight. This simple thing is often overlooked as a source of trouble, and is also a frequent cause of such trouble. Visually inspect the terminals, and clean andor tighten them if needed. To clean, use a small, stiff wire brush or a terminal cleaner which is made for the purpose.
Plug up the new motor. Plug the wiring harness into the window motor. This will provide power to the motor so use caution. Lower your window back into its correct place on the wiring harness. Remove the tape or re-install your window. Make sure that the tabs in the bottom of the window are properly aligned to bolt it back onto the regulator. Bolt the window to the regulator. Using the bolts you removed earlier and the same extension, you need to bolt your window back to the regulator. Test your window. It should now move up and down freely when you press the switch.
