First check that the drive assembly under the outside cowal cover is not binding.
The GEM module controls the wiper speed.
Seems if they go part way up then return after the interval set that it could be the GEM.
Normally the interval runs them a full cycle up and back in one sweep operation then begins the interval all over again.
Check several positions on the interval settings to see if that all act the same.
Good luck.
Like he suggested, check different positions of the multi-function switch to see if it happens only in a certain spot. I wonder if it would help to clean or replace your multi-function switch.
