Hello everyone, I could use some info or personal feedback regarding what TIPM to purchase. Mine has been on its way out for a while now, strange wiper/high bream/squirter issues. The Dealer quoted me $1300 for the unit alone but then I saw online Dorman remanufactured units for $400 or so with a core. My questions is, has anyone had experience with the Dorman unit and would it be a wise choice?
