more than likely your resistor or a fuse, i just changed the resistor in mine and it works fine the part is about 30 bucks
why doesnt my heater work on my1985 BMW
this could be one or two things. your blend door motor or your heater core if its is your heater core check inside passenger side floor for coolant if not its blend door motor part is about 60 bucks but cost alot to get put in by dealer!!!!
Low coolant? Bad thermostat? Heater control cable not adjusted properly? Heater core airbound? Heater core plugged?
Check temperature control cable for binding.
I have exactly the same problem on my 2000 Still looking for the answer
heater will not blow on a 1996 ford contour
if the heater does not blow out warm air change the setting.
heat core. leak. thermostat. no antifreeze.
A cracked engine block
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.
Blow up, like break, or fall off. Most likely the bearing is shot. Not an expensive part to change. You have to replace the water pump with a rebuilt one.
Sounds like a blown head gasket.
