I bought my daughter a 2003 Romahome 1.9d. It has had a catalogue of problems. The first was finding out that Romahome stopped making these in 1998! Alarm bells ringing ever since. I've been busy with it but I still don't know exactly what engine we have. Had no heater and the fault is with a plastic manifold (flange) at engine rear. The heater port is blocked off and it has been changed at some point. Now I'm worried that the cooling fans don't work as we've never heard them operate. Any wiring diagram I can find shows a 2 stage switch in the radiator but all I can find is a transducer in the t/stat housing. Could anyone help me determine my engine model and if possible shed some light on the fan control? We have twin fan motors and 3 relays. I believe the relays switch the motors into series or parallel to achieve the 2 speeds. Relays have metered out fine but I don't know what controls them. Sorry for the essay for my first post but I'm running out of enthusiasm for this van
