My powersteering has intermittently been working. Comes on and then goes off sporadically. The unit is kept garaged and clean but I did reclean the module itself. Now, my powersteering check light has come on. I did have a bad battery which was replaced but same things happening. Dealership wants lots $$$$$ to just to diagnose and then advised me the modules are $3000 if needing to be replaced. My atv is a 2010 sportsman with eps. Is it possible the power steering unit costs half of what the atv is worth or are they tring to hose me. Any help from anyone would be appreciated.
