A thread said that on a base model, a relay is needed to adjust the seats but it was vague. There was no mention of a part# or where to install the relay. I called three dealerships and was given 2 part#'s. A0025422219 wich is on back order and 51004857AA both $44 bucks. I don't know wich part to order and i'm leaning towards the later but still don't know how to install. I'm at the fase where I take the car to the dealership and let them fix it. Can anyone shed some light on my dilema greatly appreciated. Scott
