When i stripped the door cards out, i got left with the daft shaped window switch with no where to attach it. Saw there were only two wires going into the window motor and figured i'd get a 3 way switch and wire it in to the dash somewhere....
One wire for up and one wire for down... checked the leccy diagram to make sure ( made note that the window lock switch for the p/s side works by interrupting the earth) Power feed in the middle, up wire on one contact, down wire on the other....
Power to one wire, window goes up, power to other wire, window goes down right?
Only it doesn't.. after some head scratching i got the tester out and found that the up and down feeds to the motor are constantly live... both of them at the same time.... you press the button to make the window go down, and the down wire holds constant voltage while the up wire loses voltage... the window goes down... press the up button and the voltage drops on the down wire but stays constant on the up wire...
So how do i replicate this into a normal switch? or switches? i'm sure there is a really obvious way, but i can't get my head round it..
Any ideas?
