Driver mirror won't lock into place
 

Just noticed my driver side mirror no longer clicks into place when manually folding open or closed. Just swings front to back freely. Just happened today. I can go to the parts yard and grab a mirror if needed, but anyone know if this is a fix I can make without replacing the mirror?

Lol mine did the same from when I bought mine. I told myself I would buy a new mirror as soon as I could find one, I stuffed a small piece of rubber to hold it in place till I bought new mirror and its still there after over a year.. One day I'll buy a mirror.
