Drove it to the club for quiz.
Got out and pressed the fob to lock it, and it sounded the horn, like a door was not closed.
All doors are closed, and when I turn the ignition on, the door open warning is not lit. However, summat is up with the back door. It is shut and window fully up. Pressing the latch to open the door does nothing. The rear wiper won't operate.
Bit of a coincidence that the opening switch would go and the car thinks the door is open at the same time but not show the door open warning (maybe it doesn't think the window is closed). I think something else is up.
Such fun, looks like some investigating to do. May just try disconnecting the battery, waiting then reconnecting to see if maybe the CCU has got its knickers in a twist again. It has been very wet recently, an inch of rain today on top of best part of a foot so far this month - dunno if that's a factor.
