Woke up this morning to see the headlamp washer jet sticking approx. 1cm away from the bumper, thought someone may have tried to nick them overnight, then I realised it was the same on the otherside. Now I know these only work when the headlamps are on, and you pull the windscreen washer lever for a few secs at least. Can the cold effect them from retracting all the way back or maybe something is frozen and stopping them going all the way down? I've tried pushing them down, but they are both stuck.
