Logitech G602 fix middle click button / wheel not working

If your Logitech G602 scroll wheel button stops working, there is an incredibly simple fix. Here's an instructable on how to fix it by replacing the switch, but down in the comments is a simple solution that worked for me and a lot of others it seems. Simply give the mouse a good rescue breath. Cover the mouse wheel hole with your mouth and blow hard, your mouse is probably working now!
