1995 S-10 Blazer, 4.3L H.O, Automatic, 4x4, 250,000 miles. I am having yet another issue with my 4wd not functioning properly. Push button 4wd on the dash.
4 LO engages, set in "N" push 4 LO, both 4 HI and 4 LO lights flash 3 times, you here the case lock in, and you are in 4 LO. But both lights stay on steady. Push 4 HI. Nothing, at any time (from 2 to 4 HI, nor from 4 LO to 4 HI). It doesn't matter if you are moving or not, and it doesn't matter what gear the tranny is in. From 4 LO, it will go back to 2wd as long as you are stopped and in Neutral. Any other ideas (beside buying a new truck?). This truck is still running strong and has been properly maintained all it's life, recently drove from Southern California to Central Illinois stopping only for fuel (2200 miles) and everything else is great, but I need 4 HI for the Illinois winters since I am back.
Xfr case motor has been replaced, no play in linkage, Vacuum pod replaced and vacuum lines rerouted as per TSB's in "Mitchell OnDemand" and "AllData." I am thinking the switch on the dash but would like a second opinion. Is there a way to remove the electrical BS and install manual linkage instead of the push button? I have everything out of an '89 4x4 Jimmy, but I am unsure of the internals matching up as far as the t-case to tranny. (And yes, I realize I would have to cut a hole in the floorboard. That's just minor mods. Or is it possible to put a 1/2 ton 80's model t-case in? Thanks.
have the same problem?
