Hi All. First time i've ever used a forum so please tell me where i'm going wrong. I have a 2010 1.5 diesel Grand Scenic. Problem is earlier today the wipers didn't come on at all. The rear works ok as does the front water spray/cleaner. I tried them again about 10 mins later and they worked. Basically sometimes they work sometimes they don't. Any ideas to what the fault is would be greatly appreciated. I've only owned the car three days but today was the first time we have had rain since buying it. Thanks.
