I've had over 10 G-bodies and every one of them eventually did the same thing. The seat stops moving. The motors are making noise but none of the directions work. I haven't torn it apart because my son has been driving it everyday. Is there a common failure part that I could order so we'll have what we need when we do tear into it? I have tried and failed to find a complete assembly anywhere, and haven't been able to find an adjuster from a different car. There just aren't any to be had.
