This automotive maintenance tutorial was specifically written to assist owners of the second generation (2011, 2012, 2013, 2014, 2015, 2016 & 2017) Chrysler 300, 300C or 300S sedan in checking or changing a blown fuse or a faulty relay in either the engine bay or the trunk electrical panels.

Owners of other Chrysler, Dodge, Jeep and RAM vehicles such as the Town & Country, 200, Pacifica, Avenger, Charger, Journey, Challenger, Dart, Durango, Magnum, Grand Caravan, Grand Cherokee, Renegade, Wrangler, Compass, Liberty, Patriot, ProMaster, 1500 and C/V Tradesman minivan may also find these DIY instructions to be helpful.

This 2016 Chrysler 300C is equipped with the relatively newer style of low profile mini blade fuses.

A yellow plastic fuse puller tool is included on each of the two electrical blocks. If the tool is missing, you could use a pair of needle nose pliers with rubber insulated handles.

Engine Bay Fuse Panel
The first two steps are to open the hood and then move to the left side of the vehicle.

The engine bay fuse box is located on the left side of the car and behind the windshield washer fluid filler tube.

Gently push in the tabs on the front and rear edge of the fuse box cover to release the retaining clips.

Lift the cover straight off the top of the fuse box and turn it over.

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

Open Trunk Lid
There is a yellow plastic fuse puller tool located at the left rear corner of the engine bay fuse block.

If the fuse or relay you'd like to check is not in the engine bay fuse box, it should be located in the second electrical panel in the trunk.

Open the trunk lid and lift the carpeted mat and the floorboard.

Place Jaws Over Old Fuse
Turn over the fuse box cover to view the fuse location diagram and access the fuse puller tool.

Squeeze the end of the fuse puller tool to open the jaws.

Place the jaws over the old fuse you'd like to check or change.

Push In New Fuse
Pull the old fuse straight out of the socket and hold it up to a light bulb.

If the thin metal strip or "band" in the translucent plastic center of the old fuse appears to be burnt or broken, it is most likely "blown" and should be replaced with a new fuse of the same amperage rating.

If the metal bar in the middle of the old fuse appears to be intact, the old fuse might still be good. Since new fuses are so inexpensive, you should still replace the old fuse as part of your electrical issue troubleshooting process.

Push a new low profile mini blade fuse of the same amperage rating (5A, 10A, 15, 20, 25, etc) straight in to the socket.

(Some older Chrysler vehicles are equipped with the taller standard mini blade fuses. Check your old fuses before buying new ones.)

Replace Trunk Box Cover
Replace the fuse puller tool on to the engine bay electrical panel or the underside of the trunk fuse box cover.

Push the fuse box covers down in to place to secure the retaining clips.

Check the component were you were having problems with such as the radio, horn, power windows, interior lights, 12V outlet, headlights, tail lights, window wipers, gauges, A/C system, etc.

If you are still having the same issue, you may have a shorted wire some where or the electrical component itself needs to be replaced.
