How to Troubleshoot the Electrical System in a Ford Explorer

Ford's popular SUV model, the Explorer, has been around for awhile. The above-average electrical system still comes with quirks like warning lights lighting up on the dash without cause and temperamental power windows. But with a little time and effort, most owners are able to resolve the problems.

  • Locate your inside fuse panel. Ford did such a good job of concealing it that some owners can't find it. If you look under the dash on the driver's side, you'll find the 2-inch-by-5-inch panel close to the door.

  • Shut down your Explorer and restart if your ABS light illuminates your dash. Often, this resets the light and you won't see it again. The ABS system occasionally misses a signal from the main computer, but it should reset itself. However, if the ABS light does stay on or comes on repeatedly, you should check your brakes. Sometimes, all that's needed is a little brake fluid.

  • Take your Ford Explorer to a mechanic if the ABS light stays on when brakes and brake fluid level are normal. The problem is most likely electrical, and you need the code from the ABS module. The code may indicate a problem with the rear anti-lock brake value or the rear sensor on the differential.

  • Check fuses, circuits and relays if power windows stop working. If you can't find a problem, you'll probably need to look for the electrical problem in the door. Exchanging the switch or replacing the motor in the door often does the trick.

  • Look to your alternator if headlights seem to dim after starting your Explorer. It might be a loose connection. Another culprit is a loose alternator belt that doesn't let the alternator charge correctly.
