Really hoping someone can shed some light on this issue. Dashboard works fine for about 30 mins then all needles quit working and all warning lights/messages come on and stay on while driving. Dashboard stays lite up, just not reading mph/current gear etc.. Truck drives fine. Just today the driver window controls stopped working when dash quit.
Help!!!!????
