I drove over a bump the other day and lost all control functions on dashboard, turn signal, hazard, fuel gauge, speedometer, oddemeter, temp lvl, but i did still have tail lights, head lights, blower (fan) and radio. The radio and lights stayed on even after the van was shut off. Also the only way to get the lights and radio to turn off without disconnection the battery i have to unplug the fem (front electronic module)?
