  Q: How to replace the Global Positioning System Antenna for Cellular Communications/Digital Radio on Buick Lucerne?

  A: The replacement process for the global positioning system Antenna for cellular communications/digital radio begins by removing upper rear quarter trim panel pieces while avoiding paint or clear coat application on the Antenna because both can damage its performance. Remove the rear assist handles after lowering the back part of the headliner while keeping it free of destructive bending. First remove the Antenna Cable from above the am/fm Antenna module while taking out the foam tape from the connection point before disconnecting the digital radio Antenna connectors. The Antenna installation process begins by removing the Antenna bolt and expansion sleeve ahead of removing both the digital radio Antenna and then attaching the Antenna mast to the Antenna Base with screws before settling the mast. The Antenna Base requires the mast installation with mast screws then secure it at 1 n.m (9 lb in). The digital radio Antenna must be placed on the roof with the wiring pigtail routed into the Antenna shaft slot before applying the expansion sleeve and bolt which needs a torque of 6 n.m (53 lb in). The Antenna connectors should be connected while foam tape is used for insulation after which the Antenna Cable needs to be reinstalled above the am/fm Antenna module using hold down clips. The final installation step involves placing the headliner on the roof panel while replacing both rear assist handles and then reattaching the upper rear quarter trim panel.
