4x4

ive got a 14 commander 800 and the 4x4 wont engage. when I start it the icon comes on dash so I know the icon works, I don't hear any noise from it trying to engage. I bought a new switch thinking that was it and has same problem, no noise and icon doesn't come on. everything on machine works...

Have a 2012 can am commander that the 4x4 is working intermittently. Seems like its not working more than its working. The 4x4 light is on so i suspect the switch is working properly otherwise the indicator wouldn't be on, there are no active fault codes, not sure where to look from here...
