For checking ground circuit, usually an ohmmeter would be sufficient provided you know what you are doing. It is not easy to explain the process but I will try and see if you understand.
Unplug the connections for the window circuit and test the ohms for the ground wire to body and if resistance is more than 1 ohms, the ground circuit could be poor and cleaning and retightening the bolt holding the wire might help.
Anyway I am not sure about the exact problem of the power window and the symptom you mentioned were rather briel so the answer about the ground circuit was only a wild shot.
If you can explain the exacty symptoms, I might be able to understand the problem better and show you the correct way to go about.
