Heater Control Connections?

I was wondering why I was getting no sign of airflow from my heater.. Had a look, and the reason might be something to do with the cable not being attached to anything.

Can someone tell me what's missing in this photo?

Control lever for the ventilation flap for directing air to the cab or demist, or off.

Thanks.

So there's a lever meant to be on the pin sticking out the side, under the cable?

Shouldn't be too hard to cobble something together, I guess.

Heater box, earlier models (but the right way around - GM manual TS949 has it back-asswards for RHD models).

(1): ventilator shaft spring clip.

(2): control lever.

Arrows indicate clips to remove to separate the two halves of the case (control lever and spring clip removed).

Expect to have to do this because the 'figure 3' clip for the outer cable often won't hold in the casing slots because they're worn or broken -

Fix for slots worn or broken is to dismantle the casing to fit a bolted-on metal support plate with slots to take a 'figure 3' clip or drilled for a screw or bolt clamp pinched from something else.

Bend in inner cable after adjustment is to prevent pull-through in the screw nipple when the screw works loose, which it will do eventually.

When I last got chance to have a look, I managed to turn the end with a pair of moles so at least it's on demist now.

And then discovered the drivers side vent hose isn't connected to anything at the heater end. That'll be fun to get to...
