A few weeks ago my front wipers where set to intermitant during light rain. I noticed that they where a bit staggered, i thought they where just mukky so cleaned the window and the wipers but they stopped working. They did work on normal but a few days later same problem. They worked fine on full pelt but last night during the persisting down rain they stopped mid wipe and would not budge. I tried againg to get them working today and they worked for about 10 mins with the blades raised off the glass but then gave up. The back wiper works fine.
I have looked all over the internet and get different answers from differnt places. I have tried to change the fuse but that didnt work. They still work every now and again as do the water squirters but they have now refused to work. I was given a quote by Vauxhall over the phone of £298 parts and labour to fix them but i want to rule out all other possibilities first.
Does anyone no what i can do to troubleshoot the problem??
