It seems that lots of folks have dead 12 volt battery issues that occur after something unusual happens with the radio, particularly with the radio not shutting off when you open the door. We have found that this happens most often in cold weather. Hmmm. Could there be a connection between cold weather, opening the door, and dead 12 volt batteries???
Well, I think so. As it turns out there is a push-switch located under the door latch inside the door. Check this video out https://www.youtube.com/watch?v=HyTFsi809Hs
It shows the switch and describes what happens when the switch sticks.
I checked with Ford and unfortunately they do not sell just the switch. You get to buy an entire door latch just to get the switch so the cost of the switch (without considering the labor to install it) is ~ $140.
Some folks apparently have had success by spraying WD-40 in the lock to free up the switch. That's what we are trying.
