Heater resistor pack
Posted 06 January 2010 - 06:18 PM
I put my car into a garage because it could well be a multitude of problems, but the garage came back and simply said it was the resistor pack after all. With Christmas and New Year and items not being in stock, they couldn't replace the part and I needed the car.
So I purchased a new resistor pack from a local Ford dealer today and fitted it. Unplugged the wiring housing from the back of the old pack and slotted into the back of the new one. I ran the engine for about 10 mins and it still blew cold air, on every setting, both fan speed and direction. I also moved the temperature dial from hot to cold a few times to see if that triggered anything, but nothing.
Any further suggestions?
The car in question is a P-reg Mondeo estate 1.8 TD LX. New radiator fitted end of 2008. Had a trickle of heat before it was replaced.

Does the dial for the hot/cold move freely,and all the way round? or does it feel a bit stiff?

The hot/cold dial moves freely all the way between the extremes.

The resistor pack on mine only controls all but the full speed fan setting.

My mk2 recently blew cold only, after the water pump belt disintegrated. The temp gauge was towards the high end of normal, but didn't seem to overheat (bizarrely). My sister was driving and didn't notice anythign amiss except for a 'funny sound' - on high alert, I jumped in and the first thing I noticed was a high gauge. I was just praying she hadn't everheated the engine and caused head gasket issues.
If its a lack of circulating water, then I would expect your temp gauge to be reading high?

When I bought the new resistor pack I was in two minds getting a new temperature sender. Not sure whether that would affect in car heating? I replaced the thermostat 6 months ago with a generic Halfords model.
The dash temperature gauge always points to the N on NORM, never had the needle pointing in the middle. It was actually reading just below the N until I added some antifreeze to the radiator.

I guess the flap or valve which mixes the cold/hot air is stuck open to cold?
How do you release that? A quick response before the sun goes down will be very useful.

Reading other posts on heater flaps I looked deep down in the footwell, by the clutch pedal and on the left hand side you'll see a white arm. Near by you'll see a cable floating freely in space as in my case or it may still be attached to the white arm.
Luckily, which suggests this has been a problem before, the plastic housing had been removed (I could be mistaken). It is this white arm that links into the flap mechanism. Move the arm forwards in the direction of the engine. Lovely warm air should come flooding through.
The black catch or clip at the end of the cable that comes down from the hot/cold dial had detached itself from the white arm. I noticed on mine the cable isn't actually long enough to push the flap all the way over to full heat.
By detaching the cable, one can push the flap a little bit further open to hot.
Hope that helps anyone else in that situation.
