Iwas on the highway last night with my wipers on full blast, then all of a sudden my passenger wiper start slamming down on the piece of plastic it sits on when in park position. so i turned them off real quick them turned it back on it was fine for a minute then it started banging hard then the passenger wiper slammed into the driver wiper bending the sh*t out of the blade. now i haven't pulled off the cowl yet but from searching i understand there is a motor and a trans for these.
Now my driver side works normal perfectly fine.
So since I haven't looked under the cowl yet; am I looking at getting a new trans or a new arm or could this be one of those stupid "TAB" issues?
