hi, first post so hello all. i had a failure of the windscreen wipers on the car and read through all the good stuff on here, followed the tis disc procedure and was on the verge of handing frauds lots of cash for a new wiper motor when i decided to check all the fuses again. the fuses to do with the wipers, washers etc all fine. however fuse 33, which on the fuse card shows as a fan,nothing to do with wipers etc, had blown?, changed fuse and wipers now work! theres nothing like a random fix.
