Urgent Heater working on number 4 only

[Cully325]

Heater was working on all speeds. Stopped on 3 yesterday and then started ok again. Stopped on 1,2 &3 tonight, works on 4. Have checked fuse and relay with donor - both ok. Need help please.

Sounds like the blower motor resistor to me, haven`t got a clue where you find it though, sorry

thanks mate

You need to find the resistor pack, sounds like its burnt out... it should be near the heater fan in the airflow,

i think its number 6, should have 4 wires going to it.

Where it is depends on the age of the car. Chris-W was posting up pics of the later type yesterday.

In that case, Chris's pics are applicable!

Thanks Brian, I have just been out in the dark to have a look. I guess the best place is at the dealers? It appears to just pull off? Is this right?

As far as I remember, there's some kind of obvious clip that holds it in. Release this and it pulls out.
There's a thermal cut out in it that may respond to cleaning if it's contacts are the problem.
Either get one from a scrapper (my preferred option), or ask zimmerbimmer1 for a price on a new one.

Thanks for your help Brian. Invaluable.
cheers
