ok the winter is here and im trying to turn the hetter on but it seems that no heat is comeing in. i looked under the dash and the litel motors are turneing to open it. The car runs fine the coolant hose is hot that goes in the car so does the out one. what can it be the problem???? are there any other things i have to check??? o and the fuse its ok. i just cant figure it out.

 

I suspect that the door that controls the airflow across the heater core is not operating or not operating properly.

 

i am experencing the same thing in my 1995 A6 Audi. Please let me know what you find.

 

is your temp guage moving. you thermostat could be bad. if you hold it at like 2500 rpm and you get heat you probably have a flow problem somewhere. follow the hoses going to the heater core and see where it goes from hot to warm.

 

I'm having the same problem. The engine is making enough heat. I think it's the flap that controls the heat thru the core. Does anyone know how to manually move the flap?

 

id check the heater control valve. it should be vacuum controlled. its under the cowl area. remove the plastic cowl trim and you'll see it where the two heater hoses go into the heater core. make sure your getting vacuum and the valve will hold vacuum itself.
