COULD BE A BAD HEATER CORE COULD BE A BAD HEATER CORE sounds like the heater control switch needs replacing.if that doesnt fix it, you need new heater core
The heater is like a small radiator(heater core) usually located in the dash. The fan blows air through it and heats the car. There are two heater hoses that carry coolant to & from the heater core.
It acts like a small radiator to warm the interior. Warm/hot coolant from the engine circulates through it, while air blows across it. This air is warmed by the coolant, then is directed into the passenger compartment to warm the car.
It sound like the thermostat is broken
It starts with your blower which is usually located on passenger side under dash then blows thru a sealed vent thru your heater core then from there goes thru almost like a sealed box that controls which vents it goes to depending on what your setting are on.
It is an infrared temperature sensor for the heater and ac system.
I would say that your heater core is ok...it sounds like you have a bled door promlem in the dash.
Sounds like your heater core is leaking. Does the fluid look/smell like antifreeze? if so, time for a new heater core.
heater core is more than likely leaking..
Sounds like heater core is leaking and what you are seeing is antifreeze
A car heater that smells like burning rubber could be an indication of a belt that is slipping. The slipping belt smell can be drawn in from the engine compartment into the passenger cabin.
