I have a 2013 CF Moto Z6 EX.  It runs fine. The problem is that when I press the button to engage 4-wheel drive, it won't engage and the front wheel lights won't light up on the dash like they are supposed to.  I can push it on into diff lock and still nothing even though the diff lock symbol will light up. I can't hear it engaging either.  I'm not sure what's wrong. Any ideas?

Pull the actuator and take a look inside. See if it moves plugged in, hit the button. Far as I can tell, most of the CFMS use the same one. You are not the first to ask about this. Do a search and read up on it.
