Very common problem on 2nd gen Blazers, mine use to do it also.
The flasher is located behind the glove box door, just push the sides and it will fall right out.
You can then turn on your turn signal and hear the clicking, thats your flasher.
Here's the way I fixed mine months ago.

98+ flasher/relay mod for the fast flash - S-10 Forum

 

Fixed.


I checked the large bulb on the drivers side on the lower part of the reflector.''apparently it was slighty loose.


I snugged her up and the signals flashed normally.''

No need for a new flasher.

Thanks.

 

when i got into town the left signal was flashing fast again. i will check the end of the bulb to see if it is messed up or maybe the socket is not good.

i thought i solved the problem......................
