They have cable driven regulators. Over time the cables either break, or get bound up which breaks the plastic pully. You need to replace the regulator. I have replaced my drivers door 3 times. Passenger door once, and both rear doors once. It is easier to replace them as an assembly. (Motor and regulator together). If you only do one or the other, it can be difficult to respool the cable to the pully if it should come off.
