Default No brake lights no turn signals no 4 way flashers

As it says, suddenly I have no turning signals, brake lights or 4 way flashers, not even the sounds of the clicking for the lights. I hear no relay or anything. Headlights and tail lights work great though. Any ideas and where do I look to do anything to fix it? It is a 2001 Dodge Ram 1500 WS 6 cylinder.

I have absolutely no kind of brake lights at all, the tail lights come on as does the headlights, but nothing else.

Have you check fuses? I would check the brake switch with test lamp and see if you have voltage at the switch.

Do you have power door locks and do they work if you have them.

Also Just thought of this. Do you know if the recall was done for the ignition. Because the wires get hot and burn, causing all kinds of problems. And i believe there is a fuse in the fuse box that get relocated.

No power locks or windows, I do know the ignition switch has been replaced right before I bought it 3 years ago

Here's the issue: The brake lights by themselves get power from fuse 5 in the PDC. The CHMSL is spliced in before the multifunction switch, if you don't even have that working double check fuse 5. Not visually but with a voltmeter/test light. The turn signals on the other hand get power via fuse 4 in the PDC (the rear brake/turn signal lamps get powered by different fuses depending on braking or turn signals) and the 4 way flasher should work regardless of any possible issues with the ignition switch or fuse 5/brake light switch or similar.

You may have a double fault, two fuses or a fuse and the mf switch, or fuse 4 and the bulbs in the CHMSL. As already suggested, start with troubleshooting the brake lights: Power on the white/tan wire at the brake light switch when depressed, same white/tan wire ends at pin 14 at the mf switch. Should come out on pin 12 (brown/red) and pin 15 (dark green/red).

Probably the multi-function switch in the steering column, not hard to replace, just unhook the battery first, and you will a T-20 Torx Security bit to get some of the screws out.
