So for a while, when I locked the van, the indicators wouldn't flash, but would when unlocking. This puzzled me. I checked the doors, all were shut. On top of that, the intermittent wipers filed to work, but strangely they di if I went over a bump sometimes. Was going to check the fuse. On my first long drive for a some time, I noticed that the bonnet appeared to be moving a little. Pulled over, checked it, and it wasn't shut properly. All the above symptoms now rectified, though what intermittent wipe has to do with central locking is beyond any rationale! I'd only done about 300 miles with it loose. Must be getting old!!!
