I notice that the ac / fan "-" (decrease) button isnt working while the + works fine. So, I'm unable to decrease fan speed while I'm able to increase it. Everything else works perfectly on the ac cluster. The advice of the Fiat service people: unable to find the root cause of the malfunctioning button. Suggest spending 20k and have the whole ac control component replaced. Silly! Any alternative suggestions to get it fixed? Appreciate your suggestions. I drive a white 90hp mjd Punto. If there is a thread on this already..point to it since I haven't found it.
