I've just had a look and it appears different to the sidekick which I'm sure will make it hard to find. I found genuine ones but you don't want to know what they cost. Have you checked the simple stuff like switches first.
I didn't get a chance to do much investigation yet... that's my plan for today.
It could be switches or connections - but I'm expecting the motor is gone or the regulator linkage is bound up somehow.
And... with the help of our friends from Google - I found this:
"Been searching for a reasonably priced fix to those notoriously slow electric windows? I was so frustrated with mine. New replacements are $435.00 from Suzuki Car Parts. We cleaned everything and re-greased. It helped but they still suck...My son just bought a 97 today and the windows work great. The previous owner found by much trial and error that Geo Prizm electric motors are a perfect fit and the windows in this car work great. The only thing is a Prizm right fits an X-90 left and of course the Prizm left fits the X-90 right. He bought at NAPA for $58.00 each and got $20.00 back for returning the old ones for a core. How cool is that? I'm going to NAPA on Monday and get new ones ordered for my 96, no more slow windows for me!"
"A couple of years when I got my x90, my window motor was bad. I got the motor out and went on ebay and search on window motors. I just looked at the photos until I saw something that looked the same. It was a toyota and I think it was a camry and it was around the same year. It was something like 93-99. But, it was reversed. You need the pass motor from the toyota for the drivers side and vice versa.
I changed computers and everything got dumped on the new one and I cant locate the photo or the vendor or the email. it was something like $50 for a new one. Found it ... 97-01 Camry - Rt side camry is Lt side X90 etc."
I am looking for a rear door (above bumper). Someone drove into my spare tire and bent up my rear door. I have looked locally and tried to find one I could get shipped with no luck. It is a dark green, but I will take anything in good condition. Also I am willing to pay for crating and shipping.
