Since you work at a dealership have you heard of this alert? I posted on another thread about this but not many real answers, I'm MIBronc., other thread name is Worried about my Bronco.
I was just about to make this same post/question! The lights do not come on when I open the doors anymore. My Bronco does Rev high around 1.4 for up to a minute, then goes down to .8... She drives fine. This has been going on for about a week.
