    Ford Fiesta car heating not working, any ideas please?

    Ford Fiesta car heating not working, any ideas please? 22nd May 06 at 8:57 PM
    Thanks for looking in. The heating in my Fiesta has stopped working. I had inconsistent trouble with it a few months ago, only once or twice where the opposite happened, it would only pump hot air and not cool down (despite turning temp knob right down to coolest, and driving for 20 mins or so). Then later it seemed to be ok again selecting either hot or cold.

    Now I have the trouble that it won't warm up. I wondered if the temperature dial was actually doing anything so I took the back off (the small dashboard section where the dials are) to check that it was turning the control on the small circuit board behind the dial (which it is). I'm not a car mechanic but do like to learn and try to do it myself (saving and learning at the same time ). Does anyone have an idea what it might be and if it's easy to fix please?

    Many thanks.

    Maybe heater maxtrix has gone?, does the car leak in water? or does the thermostat need changing?

    Check the water/coolant level in your radiator header tank and top up with twice boiled or distilled water.
    I have a fiesta and this is the first indication that the water level is dropped in the rad.
    I also had a VW Polo that did the same trick.

    Heater matrix or the radiator is gone. Is there a leak from the radiator at all? Or does the temperature gauge gone above half way mark?

    Thanks trigger_mike, fannyadams and ArsenalFC.

    The temperature gauge sits at around half way (will double check this but am sure when I looked it was half way).
    Will check the water/coolant level in the radiator header tank (with help from my manual to locate it LOL! )

    Will look into the matrix too. Thank you for all the fast replies , much appreciated. Will let you guys know how I get on with it.

    My money's on a faulty thermostat (after you've checked the water level)!

    i seem to remember a similar problems on a lot of small ford on www.honestjohn.co.uk it was something called the 'water valve' which may be faulty. I recall it was around £40 from ford and took around 1hour to fit.

    If i was you id go to the honestjohn website and post your query there too. Its in the technical section of the forum

    Have checked the water/coolant level in the radiator header tank and it's sitting happily between the min and max lines. Can't see and haven't noticed any water leaks.

    Thanks mr_accountant, i managed to find a link on there, people talking of flushing the matrix, bleeding the system etc.

    As much as I like to do things myself I think I might end up popping it into the garage to get them to have a look (not money saving I know, or doing it myself, but I am pretty limited on my car knowledge and don't want to start bleeding wrong things and so on).

    Thank you all for your advice and help. Will keep you informed what happens.

    what I do is call my local ford dealer first for advice then try to sort it cheaper than there £65.00 per hour

    why not post this query on their forum, then you will identify the problem, then buy the part from ford and take it to a mechanic to fit, it will be much cheaper than taking it to fraud.

    many older cars required bleeding, with the engine COLD and the radiator filler cap removed turn the heater controlls as you would for maximum heat and run the engine for a few minuites before replacing the filler cap, if you have an airlock in the system this should clear it

    Thanks mr_accountant. Just found same spec car with exactly the same problem in exactly the same order on honest john. Looks like it is the heater control valve. Reckon I am capable of that so will see if I can pick one up. For info, link is below:

    http://www.honestjohn.co.uk/forum/post/index.htm?t=40471

    Noticed that the original poster didn't reply as to if they got it fixed. Once I've had a go I'll drop a reply on here (and on hj too for others who get this prob), although it won't be straight away that I have a look at it. It's not snowing though thankfully!!!

    Cheers Kaya for airlock idea.

    Before buying the part asks them, they are experts, and then if the consensus is the water valve you can proceed. Worst thing to do on a car is to buy a part then find it’s not the problem?

    Many of the posts here may be correct and i may be wrong, so best to ask the pros and then decide on the balance of probabilities whether something need replacing or not.

    When I had a Fiesta, (Many many moons ago!!!!!!) the heater matrix packed up,and resulted in me replacing it.Not an easy job I can tell you,but saved me a packet,and resulted in nice warm toes.

    And by the way,I got mine from a scrapyard,and took the risk on a second hand one,but the gamble paid off.
  • bingobango
    thanks for advice all

    got it working in the end. it was the heater valve. got a haynes manual £13 of whsmith delivered to store (no postage!), got part for £20 of internet, just fitted it (took a while, couldn't remove the scuttle board as some of the screws weren't wanting to unscrew despite them turning, mangaed to get a few out to loosen it enough). Didn't lose too much coolant in the process as had some bungs handy to bung the pipes and valve itself.

    Hardest part was loosening and tightening the pipe clamps, kept slipping and twisting out of the pliers!!!

    Took just over an hour. Little test drive after, temp gage happy at half way, hot air and cold air blowing happily

    Cheers!

    I too had this issue. I ordered the Heater Control Valve from Ford Parts uk (www.fordpartsuk.com) brand new and delivered and £15 cheaper than the local Ford Dealer.

    ITs a common issue with Fiestas 97 onwards. I joined the Zetec S owners club (www.zsoc.com) and there was plenty of support and cheap parts there for Fiestas 97 +

    if the water system is full to the correct level, and the water temp gauge is in the normal position the most likely cause of your problem is the heater control valve,
    these valves fail on a regular basis, i would recommend changing the resistor as well ( the small circuit board you have already indentfeid behind the heater control.
    the valve assy is £16.89 and the resistor assy £6.58 + vat of cause.

    Is there definitely antifreeze in the system? WIth the cold weather recently if water froze in the system it may damage it.

    if your not sure either get an antifreeze tester, or just drain off some of the existing coolant and top up with un diluted anti freeze.
