The hoses get warm and after driving the car for an extended period of time today, it seems like the defrost setting does get slightly warm once the car is driven awhile (while I was driving it was early morning between -1 and 5 degrees) but the heat is definitely not working how it is supposed to. The thing I don't understand is that why does every setting move air except heat? I called the mechanic that does my inspections and oil changes and he seems to think I need to flush the heater core, but won't know for sure until he takes a look. I live in an apartment and don't have access to outdoor water and it is so cold out I wouldn't really want to do it myself anyway. Do you guys think that could be the problem? Vent moves air but when I switch it over to heat it seems like it is blocked because there is no air flow. Every other option moves air on high, med, low, etc. Thanks again.
