Since you mentioned the power slider, my geuss is going to be a broken wire(s) in the loom that runs through the console. Kind of a common problem. The loom is visible in the hinge on the drives side with the lid open.

Do you have the full floor center console?

Same. It is very easy to access to see what the problem may be.

Ever replaced the thermostat?

Radio current on all updates, and any recalls?

Move to a more modern city/area?

Welcome to the site. Who are buying the truck from?

Welcome to the site. Did you ask if the dealer could possibly expand on their very vague statement about the driveline? At this point all you will get here are random guesses and stories about what was wrong with other trucks, which may or may not apply to your situation.
