Heater Fan Not Working

[richfx]

Typical, just as we start to get some really good weather my heater/cooler fan has stoped working. Does anyone know where this is located and it's associated relays so I could check it?

Thanks in advance.

well the fuse is in the fuse box under the steering wheel.

but might be worth checkin the resistor too, but gerally if that goes it only works on flat out.

Thanks,

Ye, I've checked the fuse it's not that. I don't know where the actual fan motor and it's associated fuses are located though.

Anyone?

If the fan works on FULL speed ONLY then it will be the Resistor pack, usually the Thermal fuse on this fails so if you are handy with a soldering iron it's an easy fix.

Attached pic shows you which fuse it SHOULD be but it's an Alfa.......... Also ignore the red line on the pic, this was done for something else.

Both the fan itself and the Resistor pack are fairly easy to get at, can't remember the details but there is a Post on here somewhere which will help you, do a search.

Once you have found the fan the obvious thing to do is to disconnect from the car and put 12 Volts on to the fan itself to see if it runs. If it doesn't run then fan motor is bust. I suspect that this will NOT be the problem. My money is on a problem around the Resistor pack.

Mine stopped working because some water had got into it and it slightly siezed. The fan is on the ceiling of the passenger footwell behind the glovebox. I can't remember but think it helps to take out the glovebox. You only have to take out one screw (not about ten hey Nige??) of the fan itself and it will slide out.

I turned the fan a bit by hand and it unsiezed. Left it running for a while connected to a power supply. I really need to strip and reassemble after a good WD40 ing and cleanout as it still squeals a bit at low speed sometimes. Maybe this is your problem if it is not simply a fuse or the resistor pack. One way to check if it is this is if the resistor pack gets frikking hot as it loads up on the fan which won't turn. You could cook eggs on mine whenever I tried to run the fan before but it still works fine

Makes a nice change Dave. 1 or 10 screws, which do you prefer ????

S'pose it depends on the type of screw we are talking about !

Still haven't got together Dave, we really must get a grip.

Yeah - I'm rubbish at sorting stuff out and the time I was in Lincoln was a failure due to other events going on and the board being taken offline at exactly the wrong time. I'm a bit busy the next few weekends but maybe you Lincoln types will sort out a meet mid July, early August and I can pop up and see thee!

It's time we did Dave, been very quiet of late.

Had the same problem no heater or aircon took it to a local sparkey, he traced the problem to an extra fuse and relay not on fuse board. these are found right up behind the glovebox above the heater motor ( stupid place to put them but it is an alfa ). cost me £45 to get sorted but worth every penny.
