Hey guys I am a new member to the site and I have not yet figured out how to navigate things. I have a 2005 Xterra off road edition. We have had some snow here in the last few weeks and I noticed that my 4wd is not engaging. The 4wd light located in the upper left of my gauges is stuck on (no matter if I have it in 4wd or 2wd), however the light in the picture below disappeared? It does not appear at all. I got stuck in a little snow, and I tried to engage the 4wd and nothing helped. My truck didn't move. I thought it was my tires at first, but I should be able to move even with my highway tires. Does anyone have a suggestion as to what my problem could be?
