    i have a peugeot 406 hdi 1999 2.0,will not start,fault code is p1404 engine coolant heater relay malfunction,i cannot find this relay,does anyone know where it is?.when i put a testlight onto the heater plugs i get power for one second,when i crank it i get no power to the heater plugs,it has had new plugs and relay fitted,when the car has been in the warm workshop for a couple of hours it starts so the problem lies with the heater circuit.any help would be much appreciated.
