I tried using my 4wd for the first time the other day. When I pushed the button I could hear a relay click down towards the center console and the light on the dash starts blinking but the light never goes solid. I waited about 2 minutes before I finally shut it off. I've never had a 4wd vehicle before so I'm not sure if I'm not waiting long enough or if I should hear sounds when the system engages or what. I haven't looked at my Hayne's yet to troubleshoot but if someone can provide any headstarts I'd much appreciate it.
