Drive Train Axles Bearings problem
1994 GMC Truck V8 Four Wheel Drive Automatic

Just had tranny rebulit now 4wd wont engage. Replaced actuator but no change. Checked fuse it was burnt so I put a new one in and it burnt immediatley. The 4wd worked fine before the tranny rebuild. Help me please there is snow in the forecast! Is putting a higher amp fuse than the recomended 25amp a bad idea?

Check the wiring to see if there is a pinched wire that is shorting out. With the fuse blowing that quick that is where I would look first.
