Signal Relay location

I cannot locate my signal relay on my 99 Pontiac Montana

Not sure what a signal relay is.......

I take it that your directionals don't work, on either side? No lights are out?

If so, try this......with the key on, try left directional with your lever......now press your hazard switch, now shut you hazard switch off....does the left directional now work?

The hazard switch also doubles as your directional flasher....
