Hi Marc.
I'm not familiar with the 107, but in the majority of cases the knob pulls straight off (may need a pair of pliers and a rag to protect the knob), Then there is a nut holding the switch to the panel.
However I'd suggest you do a search on 'heater fan' as there's been a lot of discussion on this issue. There may be some other cause.
HTH, Tom.
