my suggestion would be to connect a wire direct from the battry to the power terminals on the fan motor.. if it spins then you know the fan is working and your problem is something as above - the switch or the thermostat...
and here it is before it was painted green @ inters (1996) i believe sorry about the poor pic quality they are photos of prints - no digi cam back in them days . . . . hope you enjoy them .... richie
right then i have finally found the old pics: - here you go : - pvw cover july 97 - and the feature :- I notice it has the rado dash but no leather seats yet.... richie
