Hello, I have the " abs fault-traction control off light " on again. On Star said code C0045. Which is left rear abs wheel speed sensor. This has been replaced once previously. Also had right abs wheel speed sensor has been replaced. Both in the last two years. Does anybody have any idea what dealer would charge to replace rear abs sensor wiring harness ? GM Part # 92257573. I may just take car to dealer. It is just so hot now to mess around with it myself. I just wanted to have an idea of how much that they will soak me. That is if it is a wiring connection problem. Also if anybody has installed this harness how easy or difficult might this be? Thanks.
