i realize this is way late on this forum but hopefully this will help other people with a similar problem
there is no turn signal flasher or relay, its a combination switch, but there is a fuse, in the fuse box under the dash, the fuse isn't mark well, but says;
BACK
TURN
(4WD-AT)
if you have a gl-10 this fuse also controls power windows,
i had this same issue where my turn signals and my power windows stopped working (but my hazards still worked) and changing this fuse fixed all my issues
