I'm looking for some input from group.. I was able to get the codes out of the truck: (Quadrasteer issues) C0533 rear steering rely motor circuit C0543 rear steer motor position error Based on a review I did with the eSI service manual, I believe the "C0533" means that if I replace the motor, this will be resolved. I wanted to see if you agreed with my assessment? I called the GM shop here in Anderson, In. and it sounds like it may be part # 26108739... they also said it's a different part # for my burb than it is for the trucks... Any Insight would be greatly appreciated!
