Homelink just stopped working on me
 

I'm having a hard time figuring out the Homelink for the garage. Was working perfect, and it just stopped working. No lights at all when you push any button. I popped the unit out to see if it was a loose wire, and everything seemed fine. The books show no particular fuse for Homelink, but a quick search thru a few of the ones I figure it might be lumped in with showed nothing.
Anyone mess with this at all. I'm sure I could find a used one easy from someone parting a truck out, but not sure if it is the unit itself or not.

do you have power at the connector when the key is on?

My friend borrowed my multimeter so I need to check that.
