2002 Avalanche here!
I installed a backup camera this morning, and to run the wire I pulled off the kick panel on the driver's side and pulled up the carpet on the floor. Everything looked great... except... there were shards of broken plastic EVERYWHERE. It looks like there was a big plastic piece under the carpet that ran down from the firewall area onto the floor and behind the wires and connectors in the kick panel area and it had completely disintegrated long ago. Does this sound familiar to anyone? If so, was there one big piece or several? Did it serve any purpose? The only thing I can guess is that some of the electrical stuff behind the kick panel might have been fastened to it (?)
