Fuse Powering Several Loads

WARNING: This page does not describe the selected car, but rather 333 other vehicles, including the 2003 Pontiac Vibe, 2003 Pontiac Sunfire, 2003 Pontiac Montana, 2003 Pontiac Grand Prix, and 2003 Pontiac Grand Am. However, it is still accessible from the selected car via links, so may be relevant.
  1. Review the system schematic and locate the fuse that is open.
  2. Open the first connector or switch leading from the fuse to each load.
  3. Connect a DMM across the fuse terminals (be sure that the fuse is powered).
    • When the DMM displays voltage the short is in the wiring leading to the first connector or switch.
    • If the DMM does not display voltage refer to the next step.
  4. Close each connector or switch until the DMM displays voltage in order to find which circuit is shorted.
