1992 s10 blazer 4x4 4.3l

The blinkers will not come on. No clicking noise or anything, ill flip the switch and nothing happens. i checked all the fuses and they were all good and i wiggled things around trying to find a loose wire with no luck. i wen to mess with it this morning and everything worked fine then i let flipped it back and forth double checking it and it cut out again. yesterday when driving ( when problem was noticed) it would work then stop. its acting like a loose wire i think but i cant seem to find anything anywhere. how can i tell if the relay is good? any ideas would help out, i have to work on the other side of town tomorrow

 

check out your relay for ur turn signals it behnd the glove box on the 92 there is a access panel says relay center take the cover off and check the relay it may of went bad. my 98 blazer blink relay went bad and i replaced it and works fine now.
