  Q: How to replace the Philips HID Bulb Ballast on GMC Jimmy?

  A: First step for hid headlamp ballast (Philips) replacement requires disconnecting the battery negative cable because the high voltage and current operations pose a hazard of severe shocks and burns. The work starts with radiator grille removal before disconnecting the front Bumper assembly. Remove the starter cable retaining screws and headlamp ballast cover after which detach the retaining clip and starter cable from the ballast. The first step involves disconnecting the ballast from body wiring harness before removing the support bracket fasteners of the ballast and ballast subplate. Separate the ballast from the ballast subplate by removing its fasteners from the ballast section. First orient the ballast subplate with the ring placed toward the starter cable then mount the ballast to the subplate and tighten fasteners to 5 n.m (45 lb in). Embed the ballast onto the ballast support bracket through installation of the ballast support bracket fastener and tighten it to 8.5 n.m (75 lb in). The body wiring harness should be reconnected to the ballast followed by connecting the starter cable to the headlamp ballast which needs a proper retaining clip for tube arc energization. Install the retaining clip followed by the starter cable cover with screws that should be tightened to 0.7 n.m (6 lb in). Next replace the front Bumper assembly along with the radiator grille then reconnect the battery negative cable.
