About 2 months ago, my intermittent wiper wasn't working. Only fast, or really fast worked. I changed the whole arm on the steering wheel and the wiper fuse(wasnt blown), and it worked fine.

Now today, the intermittent option doesn't work. fast, or really fast do work.

What seems to be the problem? is there a relay for the wipers?

Thanks

 

I have the same issue and have just been ignoring it. I traced my issue to the body control module (BCM)
