no drivers side seat control

The last month or so we've worked on several vehicles in this chassis line for a multitude of electrical failures. Your seat operation, heated seats, cruise, etc.. I like to always check the basics first, then work down the line. We're gifted with the GM factory tools to do so outside of the dealer however a good familiarity for that electronic system and it's operation will do. I recommend you have the system diagnosed from the switch on your seat to the body controller and beyond. Your technician might find some connection with all your complaints, but maybe not. Either way, the cost of a good diagnosis will give you options to prevent the random parts guessing, and you'll also be able to decide what items you want fixed based on the system's repair needs.
