More than likely, it is the flasher. When the flashers in my 95 LT went bad, they would intermittently blink fast then slow. I replaced both the flasher for the turn signals and the one for the hazards, to save myself the trouble of taking the dash apart a second time later on down the line. Dawn
Also check bulbs. A blown turn signal element in the bulb will also make the other bulbs blink fast. This is a design to warn you of a bad bulb either front or rear on the side you have the lever turned to.
The lights on the odometer on a 1999 Chevy Blazer might not work because of a burned out fuse. They might also not work if the lights are burned out.

how many mpg does a 1997 chevy blazer get?
Probably burned out bulb in rear one. AJ
You have one of two issues. The first is one of the front or rear bulbs are burned out. the second is the flasher is bad. I would bet it is the first one. Watch the bulbs that are flashing on the left side, then you will know which bulb is out on the right side.
Incorrect flasher relay installed.
If I understand the question, you probably need to replace the flasher. First make sure that all of the lights are working since having burned out bulbs will not supply enough load to make the flasher work.
The indicator bulb may be burned out.
Check / replace the flaher relay I have never heard of a flasher relay---If one side flashes but not the other it is not the flasher (one flasher is used for both sides) most likelya bulb is burned out
it could be contaminated or the heating circuit is burned out. replace it.
I'd guess that either there is a burned out bulb on that side of the car, or your flasher has died. The flasher would affect both sides of the car though.
A blown fuse can make your dashboard lights to not work in your 1993 Chevy Blazer Tahoe. A burned out bulb can also cause this.
