Yes, the knob with the clicks is the heater/defroster etc. Neither of
my Bs has ever had the words align with the function, however, so
switching the cables may be as far as one can go before law of diminish
returns (and of shed blood) activates.

I've never been able to get the control knob to push that valve the
last 1/4 inch and lock there, so spring and autumn I push the valve that
little distance with my hand. Thus in summer one gets no warmth to a
little warmth, and in winter one gets all the heat it can deliver to
somewhat less. Use a 190 thermostat if you want to be able to detect
warmth, and a piece of cardboard in front of half the radiator helps
reduce airflow over the engine. Also, duct tape around the oil cooler
helps it run warmer in winter.

The MGB heater controls cause one to admire the basic simplicity of the
TD heater. There was none when the cars left Abington.
