There is no headlight relays for this year, I have the same vehicle and I was pissed to find out its hard wired directly through the headlight switch itself.
I have a 1997 Chevy Blazer 4DR and the relay is located underneath the glove box.
If the turn signal bulbs light but will not flash, the flasher relay is defective, replace it.
I know that the 1 on the far left is the fuel relay
Inside the tail pipe.
Should be on top of the starter - follow the + battery cable

Yes, there is a headlight relay,
