Fuse Powering Several Loads

WARNING: This page is about a different car, the 2003 GMC Sonoma, 2003 GMC Jimmy, 2003 Chevrolet S10 Pickup, and 2003 Chevrolet Blazer. 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.
