There was a thread about the problem with the 107s heater controls a few months ago.

I too have the same problem that once the heater is tuned on with the slide, its impossible to turn off.

Sorry not sure how to fix the problem.

I think Jay has the same problem with his 107.
 
Thanks for that , I did find another forum suggesting from a couple of people that there if the strip the panels under dash there is a gold retaining screw on the heat distribution flap that works its way loose and just lets hot air through constantly I will try that this week
