I just bought a 99 Blazer today. It has an issue with the 4x4 not engaging.
Found fuse #15 blown out. When I tried to replace it, it blew out again. It has the 3 button switch.
When it blew out, there were a couple goofy electrical gremlins that popped up at the same time. 1) The fuel guage went empty and the back light for the shift indicator went out. The #s still appeared, but you could not tell be the backlight which gear you were in.
When I replaced the fuse, the above gremlins went away, but the 4x4 still will not engauge. The lights on the 4x4 switch also do not light up.
Where do I start the troubleshooting process ??
TIA!

Get a wiring diagram and all check circuits on fuse 15 for the short
