one because it is set on air only .. u need to shift it to warm first the RED mark...Secondly your heater wire must have come loose in the electricals. you should check out blendor store.com we had the same problem with our Jeep, very helpful.
It doesn't really blow it out it just warms the cold air.
the heater core was stopped up just flushed it out ok now
Your heater will blow cold air only.
The front expansion valve is clogged.
it wont blow heat itll blow cold air
you are low on coolingliquid !
THE CAUSE for this is that when your cold air is on the petrol is used to create air. and that is how cars create cold air
No, not if it's on a heat setting. Most home thermostats have a "Fan" setting that will blow cold air if the attic is cold.
It depends on the type of heater you have. It may be maintaining the room temprature or it may be warming up ( just like how air conditioners start hot )
heater core possibly plugged and leaking
No! Thermostat.
The heater valve could be failing to open for one reason or another.
