So, when I bought my 1999 C5 it had some cobbled together worn out C6 seats in it. This past winter I sourced some 2004 C5 ZO6 sport seats and stripped them down to the frame and seat bases. I rebuilt the seat bases and upgraded the seat frames with new seat wires and added some additional padding on the driver seat shoulder bolster. Installed all new seat foam and leather covers. I then installed the electronics I sourced, and the passenger seat works as it should. Now the driver seat is another story as it does not work as it should and will not slide back. The RPO codes and door controls all tell me it came with memory seats, but I removed the wire harness covering all the way back to the dash, but the second blue memory wire harness is no were to be found. I spoke with several used suppliers like C&S, Dino's and others with now help. I then talked to Contemporary Corvette, and they said that that year Vette they have seen where the build sheet and RPO codes indicate that the car has memory seats but in fact the factory shipped them without them. I have tried several different control modules, but none work in regard to moving the seat backwards. I also ran the DIC error codes and found a code for the seats of B2607H which is the horizonal position switch failure sensor code. Has anyone else experienced this issue?
