Rear wiper problem

[GSXRliterbikz]

So the other day I was driving in some nasty April 23rd SNOW and needed to use my rear wiper. Turned it on and it worked as it should. After driving for a few min. I noticed it wasnt wiping. I shut it off and turned it on again and it worked. After a few min. it stopped again. I noticed later on that even when in rev. it wouldnt wipe at all when on. A day later and it almost never works anymore. I did a search and didnt come up with much. There was someone that had a similar problem but there was no update to show a solution(drives me nuts). Anyone else have this issue? I doubt its a motor, it works intermittently. Is there a circuit board somewhere that shorts out? Fuses and relays seem fine.
