I have a 2007 Ram 1500 and when I engage the electronic 4X4 the light will blink hesitate and blink some more? Any ideas or feedback would be greatly appreciated.

 

Listen for the front driveshaft to click in. If it doesn't, then somethings broken.. Trying putting it in 4 low and then turning back to 2wd, then cut the truck off and try it again. Happened to me not too long ago when I pulled out a jeep sunk to the frame but what I did might not work for you
