Turn signals stopped working

[emissary]

After installing my replacement rear-clam latch yesterday, I discovered that my turn signals have stopped working. I know they worked very recently, but now flipping the turn signal switch in either direction fails to turn the signal lights on. The actual signal lights appear to still work, as all of the front/rear/side turn signal indicators light-up when I turn on the hazard lights. The headlights and high-beams all work as well. Is it possible that the turn signal switch is on a standalone fuse? I confess I know very little about the Ultima fuse setup; I don't even know where is the fuse box is... My plan is to send it to the shop next week, but I thought I’d check here first. Thanks in advance!
