Heat Resistor, 1990 E30 2dr Coupe

[Rumswede]

Hi,

My fan only works on 4 which is a recent thing. I was told to buy a heat resistor which I have down and thought it would be behind the bulk head but it’s not. Does anyone know where I can locate this and the easiest way of getting to it please? Thanks

Matt

Check the blower motor bearings are not sticking, often the resistors burn out because the motor bearings are starting to seize causing a higher current draw, use some '3 in one' oil to free them off.
