Hey all! I have a 93 blazer push botton 4x4 that engauges into 4 wheel when it wants to, some time it works some times it dont, anyone have any ideas what the problem is? Also is it possible to switch a push botton to a manual shift on the floor? Thanks bunch!

push four high/low and check if the front drive shaft is locked or sill loose if it is still loose i would start with the encoder motor.
do a vaccumm check at the back of the intake manifold.
do a vaccum check at the front acuator, when trying to put it in to four hi. Should be about the same pressure. if the drive shaft locks and there is the proper pressure id replace the front diffirential acuator if there is no pressure id replace the vaccum switch on top of the transfer case
