Okay, I see what you are talking about now. You original post just said they quit working, and now I see that the auto lock at speed is what quit working. My '02 is doing the same thing with some dash warning lights staying on. Just for ****s and giggles try turning your heater on full blast floor heat and let the cab get hotter than hell and see if the light goes off and the doors lock. I don't know why but that is when my lights go off, the tach starts working and the doors will auto lock. I am still trying to figure this one out but that is where I am right now.
Good luck.

My door locks don't work at all. even when you just hit the lock/unlock button on the door nothing happens. so its not just about the autolock when your driving.. what dash warning light stays on?

The glow plug light, hte check gauge and check engine lights along with the tach not working and the trans temp gauge not working. If I super heat the cab with the heater or a hot sunny day (none of those lately) the tach starts working then the check gauge light goes off, then the check engine light, then the last to go off is the glow plug light. When all is right the auto door locks will activate but no prior to all the lights going off. No codes, reset computers several times, checked PCM and VSM connections and cleaned. Truck runs and starts great. I know the Fire Dept. mechanic who has a connection at Ford in Sacramento and we are going to call him this week.
As far as your issue the only thing that comes to mind is the VSM, in researching my problem several guys have had issues with the VSM.
