Thanks, Axel. It seems that there is a problem with my car then. I'll have to investigate further...
I suspect that the relays on your car ( that's the small black boxes) weren't properly fitted, or possibly knocked partly out. I've not heard of relays coming loose during normal use, so hopefully, it won't happen again.
