Photo showing wiring harness and fabricated bracket on a 2007 Pontiac Grand Prix. Wiring harness was rubbing the A/C lines and the A/C high pressure sensor. The vehicle came in with complaint of "A/C does not work sometimes". Code scanning found code P0530 "A/C Refrigerant Pressure Sensor "A" Circuit". There was damage to several wires. All wires were repaired and the bracket was fabricated and mounted to the transaxle bolt stud to tie the harness back and prevent future problems.
