If the motors run they are probably OK. What happens with these a lot is the gear plugs get old and fail. These are three little rubberish plugs that go between the inner and outer part of the gear. http://www.amazon.com/dp/B000CO96SG is the official replacement part though I've used tons of other things to replace them.. You can usually find those in the HELP section of your local parts store.
The real gotcha is getting the motors out and back in but it looks like that may be covered already. Once you get it out open the housing and clean all the old plug remnants out and clean out the old grease. Regrease and new plugs and you are ready to go. I would clean up the tracks and regrease them as well since you are already in there.
This is most likely a cheap fix. The window motor in these cars contains a plastic gearset, with three plastic slugs that transfer power to the window regulator. These are there to make a "soft" connection that extends the life of other parts in the system, but over the years they slowly turn to mush.
You can get a set of them for a couple bucks.

You might hear people telling you to replace the plugs with something metal about the same shape. DON'T DO THIS. Replacing the plugs every now and then is much better than replacing the window regulators.
