1994 Accord ex, the passenger's window will only come half way. All other windows are operable. What could be the cause.? All electric window operated.Thank you in advance.

 

Get access into your door panel, and disconnect the motor from the window, and see if you can push your window up easily. If the window goes up and down easy, your electric motor is going bad. Careful not to let the window go, it will drop like a lead rock.
