whats up guys. After fixing the TCM on my 99 A6 I have just encounter another problem with my car and that is that both of the fans on the car are not working properly. I have searched high and low for some similar problem but haven't found older post that have the same problem as i do. After washing the engine and degreasing it the fans were not working the proper way. my Aux. fan turns on as soon as i turn my car on and never seems to turn off at all. Also, the primary fan (which is belt driven) isn't really rotating at all. it rotates very slow compared to when it was working properly.

I would be very thankful to anyone that could give me a hand with this

Check if the Aux fan still on after you push ON the ECON button ... the aux fan should stop, or turn off the the AC system by pushing the fan SPEED to none.
