156 heater problem

Hi Guys and Gals

Search didn't really help a lot on this - SO -
My 2001 156 heater decided last night to only blow hot air.

I have the old style non-digital climate control with the three knobs!

All blower fan speeds work OK
On auto - the blower fan speeds change correctly (ie as I select temperatures futrher from actual cabin temperature, the fans speed up to give higher flow) - so i am assuming the temperature sensor inside the car is OK
All flap directional settings seem to be working OK - ie I get air directed to all appropriate areas when selected.

It seems that whatever mixes cold air / hot air in the right proportions has failed.
Some kind of flap? Stepper motor?
Seems I get full temp hot air no matter what.

Anyone come across this before - and how easy / expensive is it likely to be to fix.



PS - Merry Xmas and a Happy New year to all when it comes!!
