I have a 97, and heater quit on wife yesterday..It had been squealing when starting for a while, so I think blower is shot..also a few months ago battery was completely dead one morning, when I charged it up, found heater to be running on high even with ignition in off. Found that by removing high speed fuse blower quit and no more dead battery but also no high on fan even though other speeds worked well till now. My question is what else is wrong along w/blower, is there a relay in there that needs to replaced?
