replace anti-freeze, replace thermostat
Cause its broke!
if the heater does not blow out warm air change the setting.
Either the linkage from the temp control unit to the valve on the heater core (which is behind the radio and temp controls) or it is the heater core itself.
The heater does not blow air because it emits infrared rays that have heat molecules within them, thus releasing heat, not blowing it. A heater does not blow air becasue there is no moving air source within the heater. The heater emits infrered rays that cause heat to slowly flow out of the heater.
check thermostat, might be stuck closed.
The heat valve is stuck open.
Your heater will blow cold air only.
The front expansion valve is clogged.
Isn't a heater supposed to blow warm air?
When you have the heater on, does it just blow any air at all? or no air?
It doesn't really blow it out it just warms the cold air.
heater on at idle and will not blow warm air. when moving it blows the warm air from the vents. what will cause this
