I have a 2002 Screw and I used the 4X4 on Thursday worked fine went to put it in on Friday and nothing happened. The light on the dash still lights up when I start the truck but I get nothing when i flip the switch. My first thought was that the switch was bad, but as i messed with it I am able to get the truck into 4X4 when I first start it up it will switch in and engage and the light will light up, but then it will not come back out unless I turn off the truck and start it again switching the switch right after I start it. Also when I start the truck and even if I do not do anything with the 4X4 I can hear what i believe is the solonoid clicking. Didn't know if anyone had ran into any problems like this any advice would be appriciated. Thanks, Travis
