Thanks for the information. I know that the right side wiper module plugged into the left side headlight module but did not think there would be anything wrong with the left side switch since all lights and signals were functioning. I will see what I can do about replacing the left side multi switch and see if that solves the problem. From all the blogs and information I've read, the Chrysler TIPM seems to be have been a very bad idea. Either that or the dealers are ripping people for unnecessary TIPM replacement.
