93 ranger xlt 4.0 2wd reg cab no turn signals

[chainbreaker2012]

So 2 weeks ago on way home from work a large squatted truck lost his chrome 3 ball tow hitch in front of me. I hit it on my bumper and it smashed through my driver's side turn signal. Dued was going to stop untill he realized it hit my truck and he floored it. un plugged that turn signal and the others worked for about 2 days, then stopped. Fuse is good and new flasher with 12v going to one pin. Can't find my Haynes manual to check wiring diagrams but im guessing maybe the multifunction switch failed? Picture attached. The marker light lights up on new signal bulb but no turn signals on either side.
Dent in bumper is from the hitch along with damaged corner lense.
Any advice is welcome and thank you in advance.
