How to Troubleshoot Fuses on a 2002 Chevy Tahoe
- 1). Locate the fuse panels on your 2002 Chevy Tahoe. The main panel is inside the car, on the side of the dash next to the steering wheel under a plastic cover. The secondary fuse panel is under the hood on the driver's side, again usually under a cover.
- 2). Pull the fuses, either with your fingers or with the plastic fuse puller inside the fuse panel. Inspect each fuse for obvious breaks. Replace any broken fuses with new fuses of an appropriate gauge. The diagram on the back of the panel cover shows which gauge of fuse is needed for each fuse location and what that fuse supports.
- 3). Use a fuse tester to check the fuses. Ground the tester to a neutral metal, such as a bolt or metal plate. Turn the key in the ignition and press the tip of the tester to each metal end of the fuses. If the bulb of the tester fails to light, the fuse is broken and needs to be replaced.
- 4). Check the fuses with a multimeter. A multimeter is a multi-purpose tool that tests the voltage in electrical components, such as the battery and alternator. Ground the multimeter, turn the key in the ignition to the "On" position and touch the end to each fuse in turn. If the multimeter shows no reading, the fuse is broken and needs to be replaced.
