Not saying its a definite cause and I'm no expert but I've heard of this sort of thing happening and electrics misbehaving after power surges i.e. fuses didn't do their job. A while ago I stupidly jump started with the polarities wrong way around (this was the single most stupid thing I've ever done for so many reasons - but thats another story!), lost ignition lost everything luckily the fuse did its job though and after an AA callout and replacement fuse all was fine, while waiting for the AA to arrive though I remember doing a bit of research on the web at the time and heard of many people experiencing problems with locks, windows, sunroof etc only partially working or not working at all after a reversed polarity jump start.
