'99 buzzing from flasher module

My '99 blazer buzzes from the flasher module. Replaced the flasher but it still buzzes. Stops when I activate the turn signal...the turn signal makes the "blinking sound" . When i cancel the turn signal it goes back to buzzing. Buzzes continually.

Where is the buzzing coming from?

Thank You for responding so quickly, The buzzing is coming from the flasher itself. I put my hand on the flasher thats located behind the glovebox and that's where the buzzing is coming from.

I would suggest first replacing the flasher.

It is cheap and could be the easy solution.

I had something similar to this problem with my 98 Blazer. It would buzz and/or click continually until I had the turn signals on. I had to replace the mutifunction switch (the turn signals/wipers/cruise control stem) to get it to stop.
