windows work improperly on 1999 Dodge Intrepid

both back windows stopped working at the same time and now a year later the passenger window can only be operated by the drivers window control the passenger control does not work? could this be the motors needs to be changed or is it just the switches?

The only way id to start with testing the window switch then proceed with door panel removal and testing the window motor and checking the regulator or you can get a price here and find a shop here
