Flow Regulator on dashboard

I THINK thats what its called!
Anyway, the three dials, one radiates heat/air to given location ie drivers' feet/drivers face/windscreen etc, the second is cold to hot and the third little swine is 0-4.
Now 0 is off, I have NO 1 or 2 at all, and 3 works fine, albeit a blustery noise.
Why do 1 and 2 not work? Is there an easy DIY solution ie WD40 squirt necessary or is it something 'expensive'?

It could be a resistor on the heater motor?

will a garage mechanic rub his hands together in anticipation of ripping me off just as he's wondering where his Xmas bonus is coming from with a limited number of shopping days for Christmas?

Quite probably, what car/van is it on?

stuff like this is usually heater resistor. or could possibly be dry solder joints if its a car with electricly opperated dials as oposed to old fashioned types with cables etc

A Rover 25

I won't be sad to see this one leave. Pile of junk........every few months something else breaks!
Nothing major, just pissy little things that add up after awhile

take off the glove box and you will see the blower fan housing; dismantle this, the fan should be a centrifugal type. once you have take this apart you should be able to see a unit that has either 2 wires or 3 "wires" on. the thinnest wire will be burnt out. this controls positions 1 & 2 on the fan control.

those wires heat up when you turn the fans on; you'll know when you see it which bit im on about. you just need to get to a scrapper and get a replacement; im not entirely 100% on this but i think the ones from the rover 45/400 and the honda civic ones fit too.

you could replace the wire but may need advise from a spark as to which "thickness (hence resistance?)" to get...
