I'm looking for the model year of the geo prism window motor, mentioned in a fix for the x-90's problematic motors. Supposedly they are identical if you switch what side they are installed on the prism.

Don't know about Prism but I've just acquired an X90 that had an inoperative drivers side window.
Turned out to be the switch but in doing the research I learned that Toyota Camry motors 1997-2001 are a direct bolt in swap. Same drill - buy the Camry right to fix the X90 left. Probably the same motor as the Prism.
You'll have to splice in the wiring but aside from that it should be simple.
 
Hope this helps!
