The rear wiper on the X no longer works. I checked that it's not the common loose nut issue. The Windshield water sprays on the back so, i don't think it's the burn chip issue (I think the burnt chip on the rear wiper motor cause the water to spray continously) Front wipers works fine. I have unplugged and plugged the rear wiper and still no luck... anything else you guys think i should try?
