The difference with this problem is that I know precisely what caused it! My Focus has sat on my drive for between 5 and 7 days, and with the big freeze in the UK at the moment, various pipes have frozen to an extent (not enough anti-freeze). When I turned the ignition over this morning, the blowers were still set to 3 or 4 from the previous time I had used the car, and after a good 20 seconds, there was a haze in the car and the smell of melting plastic or fuses! (hard to tell). I immediately turned the blowers off and then engine off, before trying again - this time the engine made a rather loud screeching noise so I didn't persist.

I topped up the anti-freeze, left it to work through the system, and after an hour, everything was fine. The only problem that still exists is my blowers do not pump out any heat on any setting, there is still the faint smell of something melting, and after a 10 minute journey, the engine fan kicks in. There are no other electrical problems as far as I can tell.

I have searching various forums and websites to try and find answers, it appears that it could be a poor electrical contact of the connector on the blower motor control switch (or it's burnt out!). If it is this, what are the implications? i.e. is it easy to replace? And if it is not this, what else might it be?!

Cheers

First, anti-freeze will not thaw a frozen cooling system. Heat will. Chances are the system is still froze and that is why you are not getting heat to the cabin (heater core is froze).

I'm going to guess the burning smell is the Blower Motor Resistor, generally if it goes bad the blower will only work on setting #4. Could also be the blower motor itself, something caught in the wheel, air intake blocked by ice making the motor work harder, wipers stuck on and froze in place motor getting hot ...

The burning smell may not be anything related to the blower though. it may just be a smell from under the hood being sucked into the cabin. Best to look over the whole works for melted wires or blackened fuses.

Thanks!

Thank you for your help, I managed to have a look in daylight for the first time today, I know exactly why the fan is kicking in; water is leaking directly out of the pipe in the picture shown, at present I have no idea what should be in it's place! I have checked fuses, nothing appears to have burnt out.

Do you know what should be where the hose ends?!

Now I'm not sure if they are different or not, but on my '02 2.0 that hose goes down and conntects to a T, one side goes to the water pump and the other into the radiator (drivers side in UK)(passenger in US). on the passenger side (in UK) the hose leads to the back of the engine. LIke I said tho, I'm not sure if the set-up is the same.
