Our 2006 1.4 petrol Berlingo has cooling problems. I had the cooling fan resistor replaced by a mechanic 4 years ago, but I think it's gone again. I have the fault code "cooling function incorporated into the engine ECU". The low speed fan is not coming on, even with the a/c turned on. I'm guessing you have to take the front bumper off to get at the resistor? Haynes manual has no info on this.
