Amazon Heater Operation

I just purchased my first Amazon (1966) and I am currently troubleshooting and refurbishing the heater. In order to trouble shoot I need to find out more info on it's actual operation. Can anyone give me a quick tutorial on heater, thermostat and lever operation? Is the fan 2 speed? Please email me - thanks!

Hi Steve & welcome! The main thing that usually catches people out is that the first click (halfway) on the fan switch is the fast setting, & all the way out is slow. The temperature slider opens & closes the heater valve, but there is also a thermostat on it, controlled by a capilary tube inside the heater box. Quite often, especially when the valve has been replaced, the capilary is left outside the heater box as it's much easier since otherwise the heater box has to be removed otherwise. However bypassing this results in a (pleasantly imho) volcanic heater output :D The other two sliders control output to the screen & floor - not juch more to say really, except that there is a piece of rubber just forward of the gearstick (connects the heater into a duct that carries hot air to the rear passenger footwells) that is often split. Hope this helps! Paul

Thanks - that is very helpul!

If the sliders appear not to be doing anything, it might be worth checking the fixings (small clamps) on their cables - on mine they were loose and the cable outer was free to slide about.
