2004 Cadillac DeVille DHS

We seem to be having a problem with the power lumbar support in the passenger's seat on our 2004 DeVille DHS. The lumbar support operates, but does not move forward far enough, compared to the movement of the lumbar on the driver's seat, so it can't be adjusted enough to offer adequate back support.

I looked at the FSM to see if there is any kind of adjustment to be made on this mechanism, but there was no procedure to fix a problem like this...only procedures to diagnose inoperative lumbar mechanisms. I could take the seat apart as described in the FSM, but I thought that some of you may have more information to add before I take this step.

Thanks in advance.
