1969 Fury I turn signals were slowing down now dont work

Hey all on my 69 Fury I, my flashers work as normal but a week after a relay was added that stopped the huge power draw by the turn signals, the turn signals started flashing and clicking slower, now they don't work at all, either left or right. Very rare one might flicker on once. Any advice on this issue? Couldn't find anything when I searched. Thanks for your help in advance!
