I have a 2012 Challenger and the windshield wipers don't work at all. I took it to 2 dealerships. 1 told me i needed a new tipm. They didn't have it and said i have to find one. I found one an exact match #68105528ab and instead of waiting over 2 weeks for an appointment i went to another dealership to get it installed. They install it and tell me everything is ok. i go to pick it up and valet the ask me why the wipers wont stop wiping. They bring it back in and after a while tell me i need a tipm with body harness 68080009ae?! Mind you this car was in an accident before i bought it. I took it to a mechanic before the dealers and he made the wipers act like their acting now. What do you think steering column relay or tipm?
