2011 Crown Vick intermittent electrical BCM type issue.
What is your question?
Issue: All at once, the door ajar light stays on all the time, none of the power door locks work, the A/C stopped working, the rear and mirror defrosters stopped working, and the low tire pressure light stays on. It's intermittent, but usually all of these don't work. If I slam the drivers door a few times, they sometimes all go back to working all at once.... but when I open the door again, they all fair at once again. Clearly this is not an issue with each of the components, it's a BCM issue, or wiring??? Could use some help.
