Re: 4wd light on constantly
I,m eating my words. Finally replaced the switch for the 4x4 light. Put her into 4hi and the light came on for the first time in a year. Now it won't go off. Just checked the vacuum at the axle with it in 2wd and 4wd and I'm only getting vacuum in the yellow line. In the diagram from beee240, which line is 2wd and which is 4wd yellow or green? Looks like I'm buying a new t-case switch tomorrow but I'm trying to find out if my axle is locked now or not. If it is, it has been for months and that would explain the crappy milage.
