The blower works under passenger dash. air blows thru defrost setting and bi level setting. air also blows thru side vents and from both floor vents. air just does not get warm at all. this is with ac set in off position and when climate control wheel set on 80. i have checked the vacum all seems functional. will check to see if hoses get warm in a.m.
