Hello well im from south texas my names rick. I just bought this 1993 blazer 4x4. First time 4x4 owner. I got it for a steal of 2100 from my dad. Truck runs great ac heater power locks and windows work. Has a edlebrock intake. Small towing cam shorty headers and fulk 3 in exhaust. Only issue I have ( amd hopefully u all can help cause I need this fixed asap) is that 4x4 doesnt work. It seems to engage when I put it in 4L or 4H but as soon as I start rolling it stops working. The 4wd fuse was popped so I pyt a new one in. Amd when I emgaged it the censor that goes into the diff housing on the front axle a small tube like object starting smoking amd leaked a bit of axle fluid. So what could I be? I THINK its the actuator but not sure. Any info is appreciated!
