HELP - Winter's approaching and I have a couple issues. Trying to figure out what it could be before I spend an arm/leg fixing them. First - my heater won't blow hot air. The A/C and vent work just fine, so does the rear (heat works on it). Second - the air only blows out the defrost/floor - nothing comes out the vents. Any suggestions???
