Heater Stuck on HOT, Rusty Nuts and Fan Knobs :)

[Gray14]

The heater control on my Eclat is stuck on hot, can anyone tell me if it’s possible to remove the trim panel around drivers footwell and reach the heater valve and close it manually.

Also located the clicking sound from the engine to be a blown gasket; manifold end to 'downpipe,' and a stud is broken. How difficult a job to undo nut and replace gasket and stud? Leave to professionals or DIY? Sight of 40 year old rusty nuts put me off a bit.

How is the Otter Switch held into the gasket. Mine just has cable ties.

Is it standard that the 3rd position at 4.30, on the Interior Heater Fan Knob, turns on the radiator fans?

TIA

If your attempts fail it willl be more difficult for the next person to fix it. Better know what you are doing. Welding nuts on the remains of the stud and lots of heat often work, drilling offset holes with bits of broken taps not so much

If heater is a rotary control, I guess you are talking about a series 2 Eclat?
Series 1 had a vacuum operated heater valve, mounted just inside the engine bay near the plenum chamber. even if it's cable operated I'd expect the valve to be in the same place. Either way, you should therefore be able to force close the valve in the engine bay.
