When the demister button is depressed the light comes on only as long as you keep it depressed.
There is no power at the rear demister terminals when the button is held depressed.
I have tested this with the engine running.
Is there any other condition that needs to be met for rear electric demister operation?
I dont have a circuit to follow so struggling a little.
I believe the button goes to a control and timimg module?
I have been told the demister has never worked from new.
thanks in advance dave australia

I have included a wiring diagram below check the relay. When you push the button does the relay click you should be able to feel it.
