I have a recurring & odd problem with the barn doors on my 1995 Mk 1 Eunos - when the ambient temperature rises in summer, they rise and switch on even when the switch is off. Most annoying on a warm day at work when I go to the car park and find my headlights on and my battery flat. This doesn't happen in autumn or winter unless it's an unseasonably warm day. I try to anticipate the problem by removing the headlight fuse in the car park before starting work, but I would like a proper solution.
