603 Heater Water Valve

[douglas j]

I think the valve is actually on the drivers side just above the dip and water jet foot switches, which are virtually impossible to operate as they are too hidden away. The valve is not like the smiths unit shown in the photograph and mine to had jammed but with a fair bit of penetrating oil eventually freed up. It also may be worth looking at the slider control on the dash as that is not the best bit of design and is held by a spring clip and does fall off, to see it remove the centre dash section and use a torch.
