Brake Lights Don't Work on 2001 Dodge Ram 1500

Brake Lights won't work. Have replaced brake light switch located under brake pedal. Have replaced light bulbs. Can't find a fuse and don't know what else to do.

The fuse is in the fuse box under the hood next to the battery
just got done fixing mine. tried fuse by battery . messed with bulbes. Then i wiggled trailer plugin and they worked. truck has 248000 miles on it so I can forgive little things once in awhile
