Megane - no glow plug light
Megane 1.9D dashboard glow plug light is not coming on.
I thought at first it was the relay unit but on dismantling the relays work when I apply a 12V source and the car starts ok.
The relay unit is fed by a green, white and orange wire. No signal is being sent on these wires when the ignition is switched on.
I presume that 12V should be sent for a short period to operate the relays and glow plugs.
Where is this 12V sent from and anybody any suggestions why the 12v is not being received to the relay unit. The main heavy 12V cable is okay.
Thanks in advance
