Wiper issues

[Sharah]

Hi,

Hoping someone can help. I have a 2009 ford ka, which has been amazing up until now. All of a sudden, my wipers just stopped and started working again They seem to be sporadic on when they stop and start so no set pattern. It is only my front ones as back continues to work fine. We have replaced the stock and the wiper motor and still doing it. I have also took it to 2 garages, where I was told that the relays were cleaned and all is fine as they were working fine. Sadly, they didnt last and continue to stop and start whenever they feel like it, whether they are in mid flow or not. Anyone have any suggestions or come across the same thing and have a solution. Any help would be hugely appreciated as it is proving very difficult. Thanks xx
