None of the buttons make either of them go up and down. When I got the car, just the rear right side didn't work, but last week the left side has given up too.

Is this the window regulator that has failed?

Anything else it could be?

Got some time this weekend (first in a long time) so I'm gonna be as productive as I can.

Much appreciated.
