We have worked on many Eurovans. It sounds like a relay may be failed in the "on" position.
I have already swapped out the relay and there is no difference
If the relay is removed, does it still run ? If so, the supply wirs is likely shorted to a power source.
NO-the fan stops when you pull the relay.
