Car: 04 A4 Quattro v6 6 speed manual 170k
My heater control is stuck on ECON and will not turn off? Did something break?. I have been having a issue since I purchased car 2 years ago with my heater. When I have it blowing MAX hot it's pretty low, but when I engage my windshield wiper fluid it's becomes louder and works in full speed, then when the wipers turn off from cleaning the fluid it goes back to normal speed, even though I have it set at Max.
I was told Audi has a feature when wiper fluid sprayed it turns down heater to prevent smell . But mine is backwards it goes stronger? I'm not sure if this is even true and cannot understand why engaging my windshield fluid would affect my blower speed anyways?
