Hi,

I remember the good old resistors used to change the blower speed. I am sure they gave off more heat than the heater matix did on my old Mini?

I have been told that on this car space is limited and my friend wants 'one of these controller things that don't heat up'.

The spec of the fan motor claims 3A current to be fused at 10A. Seems a bit low? Will check switch on and loading current before building anything.

Thanks,
Bob
