Welcome to AF. Clean and tighten all the grounds and battery cables for starters. This grinding noise sounds like the engine is running and the starter stays engaged or as it cranks the starter clutch is not engageng the flywheel, someone should check this out on site for you. The fan issue sounds like a bad blower resistor /relay, which is mounted on the blower case behind the glove box, again this should be checked out.
