The blower fan in my e30 isn't quite working correctly

it will work on 1,2, and 4, but there's nothing on 3

i took the switch out and checked that, it works as it should and i checked the connection of the switch to the multiplug it clips into which again is fine

whats the next step? where do the wires go to (are they easy to access the other end to test continuity?)

thanks again

There is a regulator that fits in the side of the heater box and regulates the speed of the fan.

I have these if you require one @ £12 posted.

Well depends, mine is easy, some is harder, just put your hand up under the steering wheel towards the motor, feel around until you find it ;) Then pull, you should maybe be able to see it, but it's hard, there is some wires going into it. Hard for me to explain ;)

http://e30.bmwdiy.info/blower-resistor/index.html This should help.
On mine i can't take the resistor out from there, i need to do it inside the car, but if you take a look down there you can see what you are looking for.
