Hi. I have a 2005 Taurus with a 3.0 motor. Yesterday, speedometer froze at 40 mph, fuel gauge and temperature gauge also don't move. Turn signals and windshield wipers don't work, only the third brake light on the rear deck works. Trunk release doesn't work, either, nor do the power windows. Any idea where to start? I've been through the fuses, and replaced one accessory relay. I am NOT anyone's idea of a mechanic!
