This quick video shows where you can find the turn signal flasher on a 1990-1993 Foxbody Mustang. Location can vary, and this shows it located behind the glove box.
Thank you for this video. This is exactly what I needed. Flasher replaced and working! Like others, I was looking at the one in the fuse block which is for hazards.
I have two flashers on my 88 hatch. One is in fact behind the glovebox (mine is hanging down) the other is on the fuse block but facing inwards instead for mine. If memory serves me correctly. The one on the fuse block is for the hazards. Good stuff bro!
