Everything went smoothly with a little money thrown at it. The dealer installed the relay under the left dash as I could not find it. He billed me 2 hours labour as most of the time was spent understanding the issue first. The seats work great and I'm really happy with the purchase. As the relay was purchased from Mercedes, part # will be different from Chrysler. #A 002 542 22 19 (seat actuator relay) $44 Cad. Thxs to everyone that helped. Next fog lights.....
