X90 window motors are not a problem. You can't get replacements anymore if you want X90 motors but you can easily use 97-01 Toyota Camry motors, they are direct bolt in but you must buy the opposite side and splice the connector.
Example, if you need X90 driver window motor, order the Camry passenger side motor. It will bolt in and comes with it's connector too that needs spliced in since X90 harness won't connect to Toyota motor.
Cheap and easy swap. I replaced both mine in my X90.
