Hi John,
Welcome to the list. As you will note we tend to wander all over the place
in our discussions but LBC's are still first in our minds. It is a great
group of people with a wealth of information on our cars.
Let me see if I can help you out, my experience is on older cars but do not
think they changed that much.

<< I have been trying to fix up some heat in the car , as it is freezing cold
here in the UK in January. I have a pull switch on the dash which appears to
block off the air supply (I assume for when I'm in traffic) but I can't find
how to turn on the blower. I can't twist the switch and there are no other
apparent switches or wiring at the back of the dash which are applicable.

The "Heater" switch is a two function switch. When pulled out it moves a
butterfly valve that blocks the air flow through the heater and into the car.
When pushed in it lets fresh air into the car if the heater water valve is of
f. With the switch pushed in you should be able to twist it part of a turn
and turn on the blower. This is all true for 1968 and older cars anyway.
<<Also, I have removed and tested the blower unit and that seems OK when I
power it up, but I notice that there is a water drip from the bottom of the
heater unit when I open the heat tap to it ( I assume thats why the heater
hasn't been used). I have closed heat tap back down. This leads to my second
question: do I drain the cooling system to remove the heater unit. Are
replacements available or are these repairable?

If you shut off the heater water valve (on the engine), remove the water hose
from the other side of the heater box and plug and clamp that hose. Then you
can remove the heater with out draining the engine/cooling system. Heater
cores are available but I would try your local radiator shop and see if they
can repair it for you.
Good Luck
