my 03 ss drivers seat has a mind of its own, every time you insert the ignition key the seat moves all the way forward and the lumbar inflates, anyone have this problem before? thanks!

 

You need to set the "Driver 1" and "Driver 2" settings the way you want them. There's actually quite a lot of personalization settings on that truck. An owner's manual will help you alot, try to get one if you don't already have one.

When I owned a 2003 Yukon, it took me about an hour to set it up for both drivers.

 

Quick and easy fix - turn the key on, move the seat and adjust it to where you want and then press and hold the 1 0r 2 depending if you have the driver 1 or 2 key fob.
