This automotive maintenance tutorial was specifically written to assist owners of the 4th generation "WK2" (2011, 2012, 2013, 2014, 2015 and 2016) Jeep Grand Cherokee with the Pentastar 3.6 liter V6 motor in checking or changing a blown electrical fuse or relay in the engine bay fuse panel.

Owners of other Jeep, Chrysler, RAM, Volkswagen, Fiat and Lancia vehicles equipped with the Pentastar 3.6L V6 motor such as the Wrangler, 200, 300, Town & Country, Ram 1500, C/V Cargo Van, Avenger, Challenger, Charger, Durango, Grand Caravan, Journey, VW Routan, Freemont, Voyager and Thema may also find these DIY instructions to be helpful.

Assortment boxes of replacement mini blade fuses in a variety of amperage ratings (5, 10, 15, 20, 25 etc) can be purchased at retail stores such as Wal-Mart, Advance Auto Parts, Pep Boys, Napa Auto Parts and online at Amazon.

A yellow plastic fuse puller tool should be included on the engine bay fuse block near two large grey relays. If the tool is missing, you could also use a pair of needle nose pliers.

Swing Open Fuse Box Cover
The WK2 4th generation Jeep Grand Cherokee with the Pentastar 3.6L V6 engine is only equipped with one large electrical fuse box in the engine bay. There is not a second fuse panel located inside the interior passenger compartment of the SUV.

It is located at the left side of the engine bay in between the coolant overflow bottle and the suspension shock tower.

Press in the two release tabs on the front edge of the fuse box to release the cover and then swing the hinged cover open towards the rear of the engine bay. 

There is a fuse and relay location diagram on the underside of the cover and also another one in the owner's manual.

Hold Up To Light Source

Push In New Fuse
Hold the fuse up to a bright light source and inspect the thin metal bar or "strip" inside the plastic center part of the fuse.

If the metal bar is broken or appears "burnt" then the fuse has "blown" and should be replaced with a new one.

If the metal strip inside the fuse appears to be intact, the fuse may still be good.

But since new fuses are so inexpensive, either way it should still be replaced as part of your electrical problem troubleshooting process.

Push a new mini blade fuse of the same amperage rating (E.G. 5, 10, 15, 20) straight in to the socket on the block.

Push down on the fuse block cover until you hear and/or feel the two retaining clips click securely in to place.
