This vehicle actually belongs to my brother-in-law, so it is doubly embarassing that what seems like such an obvious quick fix has me stumped. Car sounds in all ways as if right front wheel bearings are bad. Roaring at all times, increases dramatically when s...

1996 Dodge Caravan ES 3.3L No Start, blows fuze VIN: 1L0552L521
Well it's fixed after going in the wrong direction for the first few hours. When a fuze blows I look for shorted wires so I started chasing all the circuits on that fuze from the wiring diagram. I could not find any wires shorted to ground. At first the engine...
