Default 4x4 Works on lift but not on ground

I have a friend with a 2000 Blazer and the 4x4 will work on the lfit but not on the ground, it was giving a code of C0387. This code is Unable to Complete Shift. Any ideas?

That's a transfer case error code. DTC C0387 Explained

When it shifts on the lift, does the transfer case fully engage? Try spinning the front drive shaft? Is it free or locked with the rear?
