As I pulled up at home today, I flicked my window switch D/S to close it, to my surprise as I got out the window was down. Did the operation again and noticed the window went half way up and the went down. Has this happened to anyone else.

Check to see if there is something stuck in the guides the glass go up and down in. Maybe a bit of rubber seal etc. May also just need a bit of silicon spray.

I have seen it happen in the winter when ice has been in there. It puts the window back down as a safety feature.

will check for that cheers mate
