Found 21st May 2009
Hi
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!!!

Well first obvious thing to check is your water levels in your radiator....No water then no heat

After this is could be anything from a broken hose to a broken head gasket, could cost anything from £5 to £400 to fix

Does the fan spin?

There is no hot or cold air. I dont think the fan spin because nothing comes out from the fans?

£400 could be quite expensive

That humming noise could be your radiator fan. it comes on when the car is stationary.

oh ok I do only seem to hear it when I am stationary :oops: not too knowledgeable on this subject!

the fan should normally only come on to cool the engine (hot days & you are stationary perhaps) does the car have an engine temperature gauge? - or is there a red thermometer light showing on the dash when the fan starts spinning? - could be engine overheat due to no coolant in radiator - or faulty thermostat

The temperature gauge seems to be fine. Would the coolant or thermostat affect the heater in the car?

without sufficient coolant then you wont get hot air from the heater
does the heater blow hot & cold air when you turn it on? - may even be something as simple as a loose connection or a faulty switch on dash

At the moment there is no hot or cold air but when it works again it can blow hot or cold air, I do hope that is just a loose connection!

ok, so when it "works" all is OK yes?
if so, effectively it's just not blowing air .....in that case the problem is likely to be the switch and/or the power supply to the heater blower (IMO - as I'm not a mechanic lol)

Yeah when it works there is no problem!! In the case it is power supply or switch is that expensive to fix? Trying to weigh up if it a big job or not and to decide whether to take up the scrappage scheme or not!

shouldn't be too dear - unless it's some fancy switch for the heater? sure the garage can easily sort it if you explain that it works intermittently
scrappage scheme needs a 10yo car

check your levels, most likely problem

lol I wish it was a fancy switch but just bog standard!! Will take to garage and have a look then! Yeah we have a 10yr car at home but want a small car but dont really like the cars that are out at the moment so cant decide lol!

Btw thanks to everyone that has replied! :thumbsup:

I will check the levels and see tonight! Thanks for the reply!! :thumbsup:

If the fans aren't blowing hot or cold then its unlikely to be your fluid levels. Its usually fluid related when its blowing cold air instead of hot and vice versa.

Check the fan connections, the fan itself and also check that a fuse isn't loose. It sounds like a worn out fan or loose connection to me.

I will check the fluids thanks! So if it loose connection should be able to do it myself right? Worn out fan is that big job?

Fans are easy to replace, providing they are accessible. You're best off getting a haynes manual for you car as it will show you all of this in photos and has a fault finder section specific to your model.

I have had a look in my local Halfords for one but havet had any luck will have to try other places as the manual seems quite good!
