Driver and Passenger Windows...Motor or Regulator?

[JR3737]

My driver and passenger windows need a hand to slide up and down. I can hear the motor running but the window doesnt move. I have to push them down or up and then they move. Motor or regulator?

First thing to do is lube the regulator assembly; unlikely that both motors are going bad at same time in same way.
