  Q: How to replace the HID Bulb Ballast (Delphi) on GMC Jimmy?

  A:

  Start the hid headlamp ballast (Delphi) replacement process by disconnecting the battery negative cable since high voltage and current operate in this system. The first step starts with radiator grille removal and then moving onto front Bumper disconnection from the vehicle. Remove the starter cable fasteners then pull out the starter cable from the headlamp ballast position. Begin the replacement process by taking off the body wiring harness from the ballast followed by removal of the ballast and ballast subplate fastener from the support bracket and finally the ballast and ballast subplate from the ballast support bracket. Initiate the ballast subplate fastener removal process from the ballast before you detach the ballast from the ballast subplate. Place the ballast subplate with its ring positioned on the starter cable side before installing the ballast onto the subplate and fastening it securely with subplate fasteners which should be tightened to 5 n.m (45 lb in). The ballast support bracket fastener must be tightened to 8.5 n.m (75 lb in) after the installation of the ballast and ballast subplate onto the ballast support bracket. Secure the body wiring harness first and then connect the starter cable to the headlamp ballast before tightening its screws to 0.7 n.m (6 lb in). Newly install the radiator grille along with the front Bumper assembly then reconnect the battery negative cable.
