Re: 02 trailblazer 4wd problem
Have you checked the rear fuse box.
Under seat? Didyou check Fuse no 48 4WD rear fuse box for 12 volts both sides? It also feeds transfer case switch. Does switch have power on brown wir to it? The brown wire from fuse 48 goes threw under hood fuse box on to front axle actuator. Did you check brown wire to actuator for voltage?
