My car got in a rear crash that damaged the rear right side of bumper with some damage to my rear light, Now I was able to get the body to repair but I am unable to get the blind spot monitoring, rear tail light and park sensors to work. Except that everything in the car is running as it should, When I tried to plug the light on the left side it was working. My mechanic wants to use part t2H24473 which would change all the wires in the car. Given that its just these 3 item on the rear right that are not functioning is there an approach or some checks I can do that can just address the problem directly rather than change the whole wiring of the car and risk opening any other issues. Any check would be helpful
