I HAVE NO BRAKE LIGHTS,HAZARDS OR SIGNALS. i HAVE REPLACED THE MULTIFUNCTION SWITCH AND THE BRAKE SWITCH ALL FUSES ARE GOOD.

Any ideas on what else to check?
Yeah, hook up a professional grade scan tool an check for DTC'S -diagnostic trouble codes in the BCM - body control module. Seeing how it controls (turns on) these lights. Turn/hazard indicators flashing fast means a bad bulb or short circuit somewhere.

DTC B3949: Right Front Turn Signal Circuit
Circuit/System Description
Ground is applied at all times at G200 to the turn signal/multifunction switch. The turn signal lamps may only be activated with the ignition switch in the ON or START position. When the turn signal/multifunction switch is placed in either the TURN RIGHT or TURN LEFT position, ground is applied to the body control module (BCM) through either the right turn or left turn signal switch signal circuit. The BCM then applies a pulsating voltage to the front and rear turn signal lamps through their respective control circuits. When a turn signal request is received by the BCM, a serial data message is sent to the instrument panel cluster (IPC) requesting the respective turn signal indicator be pulsed ON and OFF.

DTC B3951: Right Rear Turn Signal Circuit
DTC B3951 will set when the BCM detects a short to ground or an open/high resistance in the RR turn signal control circuit.

DTC B3950: Left Rear Turn Signal Circuit

DTC B3948: Left Front Turn Signal Circuit

DTC B3445: Stop Lamp Circuit

Lets start at the beginning.
The turn signals and brake lights use different fuses but both go thru the turn signal switch and use the same bulbs.
Have you checked the fuses for each circuit and does each switch have power in and out ?

The first thing is to check for power at the brake light switch,there should be power to one wire the other wire power up when pedal is pushed, this will tell you if it a power loss if theres no power to switch, if theres power to switch and through switch with pedal pushed then loog at the connect for signal switch its near column big connector as brake light power goes through switch you may have fryed that wire have some watch lights as you wiggle but this is only if you have power at brake switch. if theres no power then double check fuses even in the engine compartment, mostlikly it a fuse the wiring should not of burnt with a fuse in line, theres fuses in engine fuse box that also control lights.

check fuse's

I had this problem, and to be honest, it happened to the left side about a week later...it's the board that the bulbs plug into...it's a very common problem with this model. So popular that you can normally get the socket board off the shelf at a parts store! it's extremely simple to replace, and I replaced all the bulbs at the same time!

Did you actually check the bulbs? I believe your brake lights, signal lights, hazards all use the same bulb for each side.

Your brake lights may be your brake switch just above your brake pedal.
The signals could be your electronic flasher module (EFM) located under the dash near the steering column.
Your hazards may be affected by the EFM, but not likely and the switch for your hazards may be faulty

Does the turn signals or hazards work in the rear?? Yes... it may be the brake switch or the turn signal switch (power goes from battery, to the brake switch then to the turn signal switch, then to the lights. No? .. again.. possibly turn signal switch or the wiring between cab and bed.

replace the turn signal switch in the steering column

did u check fuses under the hood on driver side lol yes ford has them thear also
