Well this morning everything was great but all of the sudden the speedometer went to zero and the over drive light started flashing and the transmission dosent know what gear to stay in if it shifts at all. And now the winshield whippers won't work. It's a real big cluster all at once. I started a thread but haven't had any answers yet. Untill my dad said it could be that the sub vibrated something lose like a sensor, which leads me to this thread...
