Good morning, on this Audi A3 there is no hot air coming out of the passenger compartment air vents even with a warm engine and the controls at maximum temperature. Visually you can see that the temperature control motor moves smoothly when the control is operated.
Touching the two water hoses that enter the passenger compartment, I feel that one has the operating temperature of the engine (warm), while the other is lukewarm.
Could the passenger compartment heater radiator be clogged? Has this happened to anyone on this car before?
Thank you
