2000 dodge grand caravan window problem

Took car to dealer to have the drivers side window fixed,put in new motor and regulator. about a month later window works when it wants to. Took it back to dealer and of course it worked that day!! Since then both passenger window and left wing window stopped working, Any Suggestions!!

A common denominator could be the switch panel on the drivers door. Remove the screws from the panel and pull it out. Now make sure the connector is secure. Might want to reseat it and see what happens.
