E90 Wipers Not Working

Hi guys, im new on this forum, infact this is my very first post.

Im hoping someone can point me in the right direction or someone has probably experienced this issue on an E90 before.

My front wipers just stopped working out of the blue & ive checked the fuse & swapped the rear & front wiper relays around & it seems thats not the problem because the rear wiper works perfectly normal. i have plugged in a launch machine as the car is out of motorplan to detect a fault code & error comes up as, AC6A switch-on relay for windscreen wipers.

Can anybody reflect on this error code?

Thanks...
