I have a renault clio 52 plate and the heater has been playing up the last couple of days. A couple of months it stopped working and a month later it started again after I stalled hehe. But in the last couple of days it doesnt work then suddenly works again. But I have noticed that when it works there seems to be a humming noise coming from the bonnet....not sure whether that is due to the heater or something else. Does anyone have any idea why this is. I will be taking it to a garage next week but just wanted to be more informed when I get there and also I have searched the internet but havent found much.
Many thanks for the help!!!
