Well when the light comes on on the dash the 4wd wont work! but if you taker the positive cable off the battery and wait for a little then put it back on it turns off the light and the 2 low light lights up but when you turn the truck off and back on the light is back on! i am thinking the switch but am not sure! i am afraid to but it in 4wd because it might get stuck in 4wd!
thanks
Josh
