**EDIT**

my first check would be on the grn/red wire from the fuse box to the turn signal switch.
Also with the hazard switch off, make sure there is power grn/wht wire from the hazard switch to the turn signal switch with the key in Run.
If there is no power, does your clock turn on with the ignition? If you don't have a clock, check fuse #15 just to be sure.

here are the three pages from the manual for the turn signals in case you don't want to wait to download the entire manual.
110-9
110-10
110-11

It could also be this problem. But I doubt it since you said yours never work.
