Hi, I have a problem on my A/C when it is set in two positions only it makes a horrible loud droning noise. It is the manual turn button type on a 13 plate 1.0 eco-boost manual petrol engine. The settings that it does it in are fan on 3 or 4 (left knob ) heater on 2-3 o,clock ( right knob ). I have had it back to the garage 3 times now, head mechanic first said it was not right then said fine, second mechanic said does not sound right not heard another one do it. The garage manager said it was ok at first as he had sat in2 cars same as mine that did it, I went over to Ford at Westwood Cross Thanet and asked the manager if I could sit in one to listen he said none the same as mine available and he would get back to me.Well the manager never bothered and I had to go back over there again,basically mine is not right and they tried to fob me off,said they had sold both the cars that he had sat in the previous day. I was told it was a big job for a small problem in their eyes as the whole dash would have to come out ! Well I,m not happy with the way they treated me and told them I want to hear another one making the same noise or I want another car or my money back. I was told to get an independent report and go back to them,shocking service from Ford !! I am monitoring it and am far from happy but don,t want the dash out and they said they would need it for around 5 days ! I will just not use those settings and live with it and when I trade it in it will be going back to the garage I bought it in good faith from. Why won,t they let me sit in another car to listen ? Please can anyone with the same A/C set your,s up in the settings mentioned earlier and see if you get the loud droning noise,thanks.Carl.
