You said the drivers side light won't come up by itself, but you can lift it up and down by hand.
It has a rod that attaches it that most likely just popped off. These flip up style lights like to get a little stiff/rusty at the pivot point from sitting (outside especially) and not being used, so that can cause some problems when you go to flip them up. This would explain you just getting the car (lights hadn't been flipped up in a while) and how it was slow going up at first (rusty/stiff hinge makes it hard to flip up) and then the next time or two it popped the rod off.
The rod you need to check for has a plastic receiver threaded onto it that accepts a metal ballstud on the door to flip it up. This could have just popped off and the fix could be as simple as lubing the headlight door hinge and working it back and forth to free it up and then just popping the rod end back onto the ballstud. There is a possibility that you broke the plastic piece that accepts the ballstud and might have to replace that, but they usually just pop off.
Like the others say, there is a red knob on the top of the motor to turn the lights up and down by hand, but the rod has to be attached for the light to move of course. This is really only benificial if the motor or wiring is bad and you have to turn it manually to get the lights up or down. I do this on mine because I leave the fuse out so the lights just shine straight through the front clear part with the lights in the down position. This gives it a cool look for running the headlights in the daytime, but doesn't let you see at night as well as with them up so I flip them up by hand if I'm going to be driving at night. I just find that easier than fiddling with removing and reinstalling the fuse.
So take a look at those things and let us know what you find. Good luck
