on most vehicles there is a speed regulator which determines the fan speed when you adjust your heater settings 1-4,this is a common problem,i dont know where it is located on the t4 but someone will be along shortly to tell you,*<:-)>

I think there is a resistor somewhere in the circuit that burns out only allowing the heater to operate on maximum speed.

I`m not sure where it is though so sorry I cant help any further mate.

It will be behind the glovebox. Remove the glovebox and it should be dead centre.
