Alfa 147 Heater
I have a 2002 147 2.0 Selespeed (UK right hand drive) with 47K miles which I've had for 4 years. Today the heater started to speed the fan then slow it down and kept doing this for the next couple of miunutes until I got home. At the same time the left control dropped the temperature to 20 degrees while the right side stayed at 21.5 degrees. When I set the control back to mono it would jump off again and back down to 20 degrees. I thought a little weird but hoped it was just a glitch however upon getting back in the car later the heater didn't work at all. Further to this the mileage on the dash flashes and there is a very faint -0 in the right hand heater control display.
I've checked all the fuses and all are OK so can this be a replay and if so what one or is this more symptomatic or a bigger problem.
Thanks for any help given
