i feel a bit stupid asking this question but what does the pull out switch do in the dash? mine has 2 arrows on it one blue and one red so im guessing it has something to do with the heating? Also is the switch that dosent click in the brake check switch?
Thanks

That cable conrols the heater tap, it shuts the water on/off flowing round the heater. The other is the test switch.

The switch you mention is operated to check that the bulb in that switch works, believe it or not 
And the bulb in that switch should light up on its own if you lose brake fluid.

Depending where your heater valve is depends which way the knob needs to be.
If you have the heater valve on the engine block (left hand side) then Knob in is hot, knob out is cold
If its the plastic valve in the middle of the pipe right side of engine, then out is hot in is cold.

If his knob (oh matron) has a red and blue arrow on it, then chances are it's of the later variety (post 1990?) and will be out for hot and in for cold.

Unless somebody swapped the valves because those plastic things are damn ugly ha ha

And the bulb in that switch should light up on its own if you lose brake fluid.
Or if you have an earlier type master cylinder without the sensor in the cap, this switch is connected to the PWDA built into the MS and will come on when there is loss in pressure in one half of the braking system.

Is this a fact? I have an RSP and have the arrow heater knob, and the tap on the head. I always thought it was in for cold and out for hot, even though mine is always in and is always chucking out warm air when the engine is up to temp. What you say Irostoke would make a lot of sense!

You may have a seized heater valve then. Get someone to repeatedly push/pull the control, and look under the bonnet to see if the valve arm is actually moving.

If you read my full explanation you will see it depends were your valve is. The valves connected to the engine block work opposite to the ones that fit inbetween the hoses.
Is your valve on the engine ??

Strange it has the tap on the head. Has the engine or cylinder head been swapped?
