First time Suburban owner

Just picked up a 2001 LT. My buddy owns a Big O tire store, so we put 20" wheels and low profile tires. Looks Really Good! But, the heated butt part of the heated seat does not work, but the back does. Any quick fix? Also, the lumbar does not work in the drives side. It is stuck in "kill the fat guys kidneys" position. My little wife doesn't even notice, but I can't hardly stand to sit there. What do you think?

It depends on the heated, im not sure if those seats have the pads underneath or if they are sold with the pad built in so you have to replaced the whole seat. For the Lumbar i would chase the wires from the adjustment handle and see if maybe you have a cracked wire. Wires under seats always suck. hope that helps.
