Fuses And Circuit Breaker problems of the 1996 Chrysler LHS

There was an extremely loud shutter and shake when this happened. Car does seem to operate the same since this problem. Gas mileage has gone down by three mpg, even after a tune up by Chrysler and fuel system cleaning. Shortly after some fuses blew. , now at 75,000 there is a lound growning sound when you steer to the left. Brakes have been replaced and need it again. Airconditioner has funny damp smell. How does one find out if this car has been in an accident?.
