I also assume you know this, but how you test the switch also matters. And of course whether all the motor current is going through it or some kind of microcontroller controlled device.
Yeah, sometimes I really enjoy my old hand-cranked windows. (But then when I drive my wife's van and it's raining and I don't have to focus all my energy on rolling up the stupid window - that's really nice too... :) ) On Sun, Jan 25, 2015 at 7:52 PM, Dawes, Andrew M. <[email protected]> wrote: > Sure, unfortunately it does seem to be computer issue or at minimum a > ground issue somewhere in the system.
