Default Sudden turn signal, hazard and break light failure

Got an 01 ram 1500 with 5.9 liter. So first my ASD relay went buggy on me and the day before I figured out that was causing erratic start ups I lost power to my signals hazards and break lights. I replaced the 10 amp red turn signal fuse in the junction box and the number 5 blue cubed 20 volt fuse under the hood. Now I'm told either the combo flasher, multi switch or some other switch under the break pedal. Help me guys.

They all go thru the multi-function switch.... Does your high-mount stop lamp work? if it does, that would indicate the MF switch......

As stated above, all these lights run through the MF switch. However mechanically the hazards switch is separate from the turn signal switching so if both don't work I'd start checking the wiring to/from the MF switch first.
