The problem is you did not give enough information for a good diagnostic. A guess on my part.
The relay switch has failed and needs replacement or theturn signal indicator multifunction switch has failed and needs replacement (I am not sure of the correct name on Chyrsler, but these are the usual names for it).
Replacing that part may solve the issue. Without a computer code from the OBD2 port it is sometimes very hard to figure this out. I am just giving the most likely answer on that product. Best of luck.
