Eberspacher D2 - still need help

Hi,

Can anyone please help, my Eber D2 is playing up. It is only blowing cold air on immediate start up, no start up cycle or pump trying to fuel. I have a mini switch controller that has the air blow option.

I have stripped the Eber down to check the filter & have checked the glow plug, I have stripped and checked the unit loads so know how to do this. I have checked the pump and that pulses & squirts fuel.

So I want to try my old switch which is below but I don't know which wire goes to which number on the contact block so can anyone help. I changed from this old switch as the temp setting wouldn't alter but at least it ran, so if it fires with this unit I will then replace with a new controller.

This is the controller that I want the wire colours to which No:

Hi again folks,

So tried my heater again today, I wired my old switch last week end with no joy, still have the same issue.

Have charged my nearly new 110amp leisure battery for 3 days and is showing full charge and loads of volts. I have tested the voltage at the heater connection & showing plenty of volts ( 12+)

It just won't do anything else other than start up immediately in blowing mode, there is no attempt to go through the start up procedure ( slow fan that builds before the pump kicks in then fires )

I have trawled the net but can't find much, does anyone have any ideas.... Please help, I want to go th dubfreeze :(
