Heater controls always on hot, knob broken

One of the last things to repair on the TF.

The heater is always on hot. (or cold now as I have moved the valve)

The valve was stuck a bit so I coerced it a little and adjusted the cable, but the knob still wasn't doing a great deal.

Took the knob off, but when i went to put it back on, the spline it is supposed to fit on pushed backwards and now is not sticking out. The knob itself has a split, so could be one of the reasons it wasn't moving the cable to operate the valve.

Do i need the console off to push this back through? Or is it likely to be buggered completely?

If you go back about six weeks you will find a post called "Knobs" have a look at that, it might give you an idea.

I had a similar problem and found the clips had come off my knobs! When I refitted them and tried to put my knobs back on one was not engaging, when I checked it had pushed the control shaft in, I had to strip down the controls again. The shaft runs through the controller and is held in place by a C clip. Replace the clip and all was good when rebuilt.
