If you can get your hand in there to loosen the pieces that grip the window, then you can pull the window out. You kind of have to wiggle the glass to get it out, but it will come out once it is loose. If you then try to see if the motor will go up and down with the window out, it will tell you if it is the tracks or not. If it does move without the glass, it might be the tracks. If it does not, it is either the regulator or the switch.
I had ordered the regulator before I pulled the old one out, so it is a lot easier to see where the bolts line up when you have the new one in your hand. THere are either 3 or 4 bolts that hold the hold thing in place. Once you take those out, the whole unit will come out. You have to unplug the wire harness before you remove it. You also have to tip it to get it out, but it does come out even though you see the frame there. It is not easy, and you will probably scrape up your arms doing the whole thing, because the edges are sharp.
If you do buy a new regulator though, you need to be aware that there are different regulators for the 2 door and 4 door models. They are also right handed and left handed (Drivers door and passengers door). I think I paid around $40 on ebay for a new one.
I hope this helps.
