Apparently this is more common than I thought.

I have a 2003 v40 that had the same issue a few months back. The dealer replaced the transistor for about $200 (US). No other parts were replaced and everything worked fine since.

It was under extended warranty, but the warranty company refused to cover the repair under some obscure exclusion. They would have covered the control switch, but not this thing. This probably does not apply to you, since it does not sound like you are in GB.

Good luck!

I too have been plagued by this issue. Would be interested in understanding what the issue is. Currently I have removed the fuse! Drastic measures, just hope weather stays mild!
