Climate Control Dial

I'm new to this forum and have a 2011 Toyota Corolla S and I had an interesting experience today. The light on the fan dial for my climate control has been on and off for some time now, no big deal, usually a simple tap will get it back on. Today when I went to my car to leave and turned the A/C on, nothing happened. No fan, no nothing. Being in Florida I was pretty upset knowing this is an issue so I lightly punched the knob in a fit of rage and voila, the A/C magically worked again. I'm not sure the exact problem, i'm assuming a wiring issue because it is the same knob with the light problem, but has anyone had this type of issue before or know how I can fix it myself?
