All the relay does is fold the mirror in/out automatically so you don't have to hold the button, right? If so, can you use the same pricipal as an automatic power window? If I remember correctly, when you push the switch to automatic down, the window goes down, via relay, then a circuit breaker trips and mometarily cuts power to the relay, allowing the relay to open(ie no power to motor). Will this work for the mirrors as well? How do the mirrors opperate, are they like a window?(motor goes one way and it it folds out, motor goes the other way and mirror folds in) Or do they opperate in a different way?
