I believe you need relays....2 for each door....over time the switches wear the contacts due to carbon buildup. If you add relays, the motors get power directly from them and the switches only use a very small amount. I believe Brother's makes a kit for the square bodies, but I'm sure you can make your own or adapt their kit...
