2000 chrysler concorde turn signal/hazards don't work fuses good changed multifunction switch still no go whats next?

The Combination Flasher, also referred to as the combo-flasher, is mounted to the in-line bracket which is located to the right of the Junction Block. The flasher can be removed by pulling in a rearward direction. The left under panel silencer duct must be removed to access the flasher. The combo-flasher is black in color for ease of identification.
The Turn Signal and Hazard Warning Flasher is combined into one unit called a Combination Flasher (Combo-Flasher). The combo-flasher controls the flashing of the hazard warning system and the turn signal system. An inoperative bulb or incomplete turn signal circuit will result in an increase in flasher speed.

Good Luck

re-sit the flasher.

The hazard switch gets power from the horn fuse which is hot all the time, and from the turn signal fuse which is hot when the key switch is on. The turn signal switch gets power from the hazard switch and both use the same flasher.
So if the turn signals work but the hazard switch does not power the lights, and both fuses have power, I would say the problem is inside the hazard switch.

bulbs check the wiring for corosion

if fuse okay,could have faulty multifunction switch.

Do your flashers work? If not it may be the flasher unit is bad. It is located under the dash on the drivers side on or near the fuse box. If the flashers work you may have a problem with the turn signal lever or the wiring connected to it.

You will need a new multifunction switch, not a fuse. this is a simple repair. Remove the upper cover from the steering wheel and then slide the multiswitch up and off. that's it

This sounds like a bad or intermittent flasher relay. The Hazzards actually use a different circuit.

I am not familiar with this vehicle, but I am confortable with wiring diagrams. I pulled the electrical diagram for the model year 1999 HD/350/SUPER DUTY (which would include your F-550). I would suspect the hazard switch in your multifunction switch/arm/wiper lever. It is the only common thing between the 2 systems, and both are wired through 2 different flasher assemblies through 2 separate wires to the multifunction switch/arm. In fact, the hazard lights are a hot battery item and bypass the turn signal switch for the front turn signals as well as the indicators in your dash.

Try to check if your stop lights do come on when you hit the brakes... if they don't, your problem is really with the hazard switch within the multifunction switch/arm.

I do not know if this switch can be replaced separately from the multifunction switch/arm, but from what I found surfing the net, the whole thing (multifunction switch/wiper lever) goes for about 50$. There are some DIY on the internet to replace the assembly, but it would seem it can be a bit tricky to replace for someone not familiar around the steering wheel portion.

Hope this helps.
