need help ! ram wiring...

update ; well so far I have talked to three dealers, not any real help, no one seems to have had this problem... one guy suggest replacing the flasher, doubtful but cheap so i ll try it... second guy thought a new harness was in order...I dont think so .....last guy suggest the turn signal switch at the column.... could it be ?
guess i will see if i can even find the flasher and go from there....

any one have any other ideas? ... thanks
