New to this forum so, Hi everyone. have a 1999, 166 3.0L, and have had an ongoing issue with the cooling fan. It used to run for about 5 seconds after the engine was switched off. Occasionally not stopping until I gave the relay box a tap. Now it won't turn on. I have had the relays out but they are two different part numbers, one of which does not register. I live in country Victoria so it is not easy to find an expert out here. Can anyone help with advice or part numbers? Many thanks.

Fixed it. I took the relay box out, removed the relays and gave them a good shake and put it all back togeter and it is working like a charm.
