No brake lights, turn signals, or flashers

Don't have a center brake light anymore. The parking lights all work. The brake lights work only when the hazard lights button is pushed down, whether the headlights are on or off.
Yes this is one of several old threads that nobody came back with what they found causing the issue.

You didn't answer the question.
What about the brake pedal?
And they only work when the hazards are on?

Push the hazard switch down and check all the lights with the key in the on position
Do the brake lights work?
Do the turn signals work? Do they flash?
Ok the the hazard button down this is the hazard off position (normal driving) so you have a turn signal and hazard issue. Check fuse 13 with the key in the on position in the fuse box behind the glove box should be a 10 amp fuse. Check fuse 27 in the under hood primary junction box 20 amps fuse. Are both these good?
Do you have standard bulbs or led’s?
Yes, I was confused at first.
Down is off, but you have to 'push down' to turn them on.
FYI; The MFSW stands for multi-function switch. Vehicles with regular flashers will use battery power for the hazard flasher then accessory power for the turn signal flasher. The electronic flasher relay in the Jeep must need the battery power to power up the circuit inside the relay.
Hate to burst your bubble, but fuses don't normally blow for no reason.
You may still have an issue with your lights.
The MFSW is a common problem that's easy to replace.

Hey Odyssey2004, you might want to start a new thread. This one was last replied to a year and a half ago.
Welcome
If you look at the wiring diag. above, you'll notice the rt.& lft. brake lights are controlled separately by the MFS.
Do the hazards work?
