The fuse block in your vehicle contains some or all the fuses that run its electrical systems. A fuse block is often made for power distribution, and fuses keep voltage spikes and short circuits from damaging the wiring and system parts. With time or due to moisture, your fuse block may be damaged, or the contacts may corrode. When this happens, you may notice that electrical systems aren't powering on. If the fuse isn't broken, check the condition of the fuse connectors in the fuse block. Also check for any melting that may have occurred due to a short circuit. If you need a new fuse block or fuse panel for your vehicle, check out O'Reilly Auto Parts. We carry fuses, fuse blocks, and fuse holders for most cars, trucks, and SUVs.
