Aux Fan Won't Turn off 2001 S500
I just had the struts resealed for the common leaking problem, and was under the false impression the howling I was hearing was the compressor trying to keep the struts pressurized. The mechanic who fixed this failed to mention that the aux fan was making all the racket. I am trying to figure out if it is the fan or the sensor or both? The fan stays on constantly, and sounds like an airplane motor, so quite loud to say the least....
Thanks in advance for any assistance.
