So i have an 06 Accord. I recently replaced the wiper linkage because the wipers were hitting the sides hard. That stopped buuuut today i was riding on the interstate annnd my wipers got connected together & wouldnt move mind u its pouring! I jus purchased new wipers 2 weeks before and tightened the nuts because they looked funny & didnt look right, fixed that and now that same nut was loose which caused them to link up & get stuck. Now im having a hard time finding the right place for them to rest because they jus look sooo out of position. Should i jus buy new arms? No matter how i move/situate the nut & tighten it its not right. Anyone have this problem?
