I have a 2001 Ford Focus, I've recently replaced the ignition switch, thermostat housing (over heating issues), and yesterday replaced the old battery. My car still won't start, nothing happens when the key is turned except a few lights in the dash try to come on, the radio will come on unless I try to use the air, whipers, or head lights, then it goes off like it can't do more than one thing at a time. The A/c, whipers, and head lights won't turn on at all. The door dings but that's about it. The positive battery terminal is somewhat corroded, could that be an issue? What else could be causing it to not crank? Thanks!
