side rear windows question

Must have been discussed but can't find info. 77 New Yorker Brougham rear windows have never gone down since i owned the car. Recently took apart drivers door window switch panel, cleaned all connections and reinstalled... Hey now all 4 doors lock through the power switch! Now i can hear the motors in the rear doors click when i ask the switch to lower windows so i know they are getting power some how. Could this be bad motors? Anyone else have this problem?

Side note, info on properly...
