Window Problem on 2004 Ford Mustang

I've been having a lot of intermittent problems with my windows. My driver's side seems to be pretty dead, but the passenger side window will sometimes randomly work. When it does work, the window goes up and down just fine. Could it be some sort of electrical issue?

it is an electrical issue. Most likely culprit is the switch, usually the master in drivers door for the passenger window. If the drivers door never works, you need to pull the door panel and check the power and ground going to the motor with a DVOM and then make sure the polarity reverses with the switch action ( up and then down ). If it does, the motor is worn out.
