1992 Honda Accord LX.
Window will not go up or down by power. When window switch is activated the motor sounds normal, as though it is working, both when activated up or down. But window will not move.

Window is able to be moved up or down by hand. With door panel off, window glass seems to be on track OK, which would justify its ability to be raised and lowered by hand.

Any thoughts? Is there a physical connection failed between motor and window, a clip or something, how to access this connection if one exists (and is failed in this case)?
Or is this the famed window regulator unit failure?

Thanks for any suggestions. Great forum for great equipment!
