Fuse Powering Several Loads

WARNING: This page is about a different car, the 2002 GMC Savana Special, 2002 GMC Savana Camper Special, 2002 GMC Savana, and 2002 Chevrolet Chevy Express. 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.
