Tony.Hang on a min.
Are we talking about the internal heater fan.
Or the radiator cooling fans

Um, just a thought but why didn't you test the old fan before you got a new one?

I'm guessing you mean the in-car blower fan and I'm also guessing that there is no power going to it?
Does this one have a climate control panel or simply a switch for the various fan speeds?

internal fan..sits in passenger footwell the control for fan/heater/air con
sits just above radio
and has a slider for faster or slower blower
and 2 push buttons 1 for aircon (lights up green) ..other (pic of a car) with i think is recerculation
both buttons light up when pushed if ignition is on
thanks tony

all wires to fan /aircon are testing live so i am guessing its the control for fan/aircon thats faulty

Tony .I think on your car there is module up under the glove box.
It may be a cartier or bitron .this controls the a/cand fan unit.
NOT ALL 406 HAVE IT.
Give you a better idea tomorrow the exact postion as there are about 4 units by it.

Didn't you fit a 2nd hand heater control panel to this last year? Could have failed again.

I'm not quite clear, do you definitely have a good earth and power supply to the fan, test it with a bulb rather than a DVM so that you can make sure the wiring carries enough current.
