This sounds like a recall I did on my crossfire years ago (I think 2006). I got a letter in the mail from Chrysler and brought it to the dealership. The part was on back order probably because everbody was requesting it at the same time. They eventually got the part and did it for me. I never asked for the details so I don't remember. It had something to do with the fan relay or something. It would cause the car to overheat but it never happened on my car. This was all written in the letter but I don't remember the details. You may want to investigate this. If it is a recall it should be free.... it was an actual recall and not a TSB. This was the only recall I ever knew about and I bought this car brand new in 2005.
