It says in the service manual, that -5A is a plausibility failure within the seat module. An -71 says invalid serial data received from it. It reads as thou the seat module is having a hard time getting its act together. An if I'm reading GM parts sources correctly, that module appears to be # 92225594. If that is correct, it can be had for $324 an up, plus the usual add on for shipping etc. If you have to go that route
