Trust me I did. Patient 94 s10 blazer 4 door 160k 4.3 (w) vortec two button 4*4 (4hi and 4lo)
So now that the truck is running good I wanna play around a little. Push 4hi lights flash (sometimes) and go away, press 4lo you hear noise and both the 4hi and 4 lo lights stay solid? in sugar sand truck moves foward back tires spin? press button again makes noise both lights stay on. And on different instances ( on pavment ) in 4 something (unknown) i press the gas and rpm goes up and truck hardly moves like the tranny is not totally engaged ( only when the 4 whell lights are on. Can not get just one light to come on. they both come on and I am not sure if it is indeed ingaging. Please help I spent many hours looking through the forum for similar issues if i missed a post please point me in the right direction.
