2011 ram 1500 cigarette lighter fuse for cigar/cigarette Dodge Forum for Truck Owners & Enthusiasts Dodge Ram Rear Cigarette Lighter
Description
If there is a power surge or if an item is plugged in that draws too much current, the fuse will blow to prevent further damage to the electrical system

I bet it's the same on yours
This is from a 2021 1500 Limited but it should be close to other 2019-2021 1500's as well with some fuses added or missing depending upon what options you have

#3 Why doesnt it turn off when the truck turns off

In this case, its a good idea to consult a professional mechanic or an automotive electrician to diagnose and fix the problem

You can find a description for each fuse starting on page 460 of the owner's manual
