My window woes, :( Options

[95CelicaST]

To fill everyone in, my Celi came with manual windows. The owner before myself had power windows installed. I assume everything was good, but then I found a receipt for replacement window regulators... and it was exspensive! My passenger window is already off the track - due to the lady friend closing the door by the corner of the window - and ever since I got the car I have had window issues.

for one - my pass. window off track, so it clunks and ticks as it goes up and down
My driver side window sometimes works, and sometimes doesn't. I press the button to roll the window down and it doesn't move. Only after I pound my door panel does it actually engage, and it makes little ticking noises as it goes up and down.

Is it possible for myself to put my window back on track? Are the ticking noises from bad window regulators?
