Power Seat Coupling
   This is the plastic safety shear pin that commonly breaks. It is designed to snap if there is too much resistance on the seat track. It is designed to break instead of cracking the plastic transmission housing or straining the motor to a point where it blows the fuse. If you have hit the power seat switch & you hear the motor(s) running but it isn't going any where it is a good chance this has snapped. They are a white plastic that become fragile over the yeras. This new GM part # 20614175 replacement coupling is deisgned to be stronger but still snap in a problem event. It is a much better quality plastic with a higher resin base.
