I had the same problem with my car - all fuses good but still no rear defog. After checking with a voltmeter, I found that the defogger was not getting power. Turns out the wires to the defogger had broken right where they leave the hatch and enter the body - they kink right there and mine had finally broken. Its a relatively easy fix, but you do have to pull off the interior panels in the rear seat area to get at the wires, then its just a matter of splicing in new wires. If this doesn't turn out to be your problem, it may be the wires in the glass - the FSM has a procedure for checking these. Hope that helps...
