Question about 2000 Ford Focus

1 Answer

Y-reg Mondeo Estate with no heating

Suddenly the heating stopped working, the dial of the automatic shows the choosen temp. and the fan is blowing at all settings as well as on the automatic setting, air con works as well and makes car even colder.
The engine does not overheat and the gauge stays smake in the middle.
I check all the fuses but not the relays.
My mechanic is baffeled and Ford apparently has never heared of it happening.

Anyone any ideas?

Thanks Mikey

    went to small Ford franchise and rhe fixed it. It was a setermoter of which there are three opening and closing some valves according to needed temp and warm air distribution.

    Problem is, that you need Ford to do it because the need the elctronic to calibrate again - but that's the cheeper part part of the exercise.

    Thanks for help and I'm looking forward to some cosier jouneys now.

Blockage in water pipes ,remove the two water pipes and try flushing through with a hose and make sure the water flows ,if this doesnt cure problem check the vacumn pipes that feed the flaps that allow the air to flow through the heater matrix.your mechanic hasnt had the experience and your local ford garage only employs 18yr old morons because anyone with any inteligence doesnt become a grease monkey as they realise that their is no future in it or decent wages.only dirty hands and you get looked down upon because you cant get the diesel oil out from under your nails.a doctor buries his mistakes mine come back ??

    the two pipes from the engine that run to through the firewall ,about 19mm pipes one from the head area and the return lower down ,With a engine thats had antifreeze all its life then clogging up is not so much of a problem but some old hands drain the antifreeze in the summer in the mistaken beleath that the engine runs cooler.Yes seen it been their got the teashirt ,If vehicle is a few years old then a good flush of the cooling system will not go amiss and new antifreeze at a minimum of 50 % ,or if in north then 100% it will not hurt it .

    old car and things go wrong ,from first reading question i would have thought it was electrical but i dont think the faults are related ,cannot say i have had these problems all at the same time .So i would expect the drivers seat to be a power supply problem ,the rear boot release to be a problem with the wires in the rubber boot from the door to the bodywork.and no sorry i dont have one around to take a quick snap of the heater hoses .

Cooling fan problem

NO DON'T!!!!!!!!!!! You'll blow it up! Go to someone like Forddirect who will get you the fan without changing the rad. What is cheaper, a radiator from a scrappies, or a new engine? They are set up for a reason, not for fun. Good Luck.
