To get to the bulb. First put the mirror in the down position. Now look between the mirror and you will see two tabs(the same color as your truck) take a screw driver and lift them up. This will remove the painted part of the mirror. The bulb # is a 921 16W

You might just need to change the Blinker fluid

 

I had the same problem on my old truck. Be careful not to spray water directly behind the mirror when you wash your truck like I did....
