Burt,
Check to see that the heater control knob is working properly and opening
and closing the heat control flap located under the dash board on the
passenger side behind the radio.
Also check the heat valve on the motor. Have someone work the dash control
knob while you observe movement at the valve to see if it is opening and
closing properly. You are looking to determine if the cable is moving the
valve lever from full open to full closed.

Subject: [Mgs] MGB Heater not working
Well fellow listers, I haven't seen any messages here for a long time, so
here we go.
I rebuilt my heater some time ago because of a leaking core.
Not a very easy job, BTW.
The heater has been functioning correctly for some time, but now I can't
seem to get it working any more.
What could be the problem?
Apart from the core, I also changed the heater valve and the fan. The fan is
still working.
The car is a 1970 B Roadster.
TIA
Bert

Hi Bert, My approach would be to disconnect hoses to the heater at valve
and at the pipe on other side, then to run water from a garden hose through
the heater. It should flow freely, possibly bringing a surprising amount of
sludge along. Then put the hose to radiator, with the valve open, and check
that water flows through the valve. This will dilute the antifreeze
mix--remember to correct it for winter season. If water flows in these
tests, try starting engine to see if the water pump pumps. You can run a
minute or so, plenty long to test this, with coolant level low.Bob
