Sounds like an electric glitch. This has been posted before so it does happen to H3 owners.
Check the fuse for the wipers. The switch itself could be bad. The BCM controls the system so it could be at fault.
Try pulling negative battery cable for a few minutes to let the BCM reset itself. Search on wiper problems on the forum or google to what else you can find. Good luck.
