Car heat wont work. What is the cause of this? How do I fix this?
The heat is turned on but there is no warm/hot air coming thru the vents. It is ice cold. How do address this problem. Where do I look for the problem (hood, dashboard, etc.) and what might it possible be the cause of this.
Low on antifreeze, leaking antifreeze or blend door in dash not switching from cold to hot.
does the heater work and higher rpm on the highway then blow cold in town or idle??--if so--the heater is air locked because the big gallon coolant tank over on the side is dry and or clogged. That is not an overflow for overheating--the engine draws from it and flows back as the engine rpm changes. If it is dry and or clogged THE ENGINE IS SUCKING AIR. I cleaned mine and heater works perfect even before warm--and at idle.
