ok so heres a friendley hint if your battery light keeps flashing on & off the seat belt light keeps flashing on & off & your heater is starting to go one day & then works the next. REPLACE THE ALTERNATOR!!The battery light is flashing on is mainley because of a bad wire that is draining the battery some of the time it is on the fire wall other times it might be under the battery. changing the batery cabels doesn't do a thing! so make sure if you can try to find all those loose wires & keep them conected of taped up.
