2006 Honda CRV-starts fine but A/C, fans, power windows, and power door locks will not operate,-radio, wipers, lights work. Is there a relay that controls the inoperative accessories or is the key switch likely at fault.

Test all under hood and under dash fuses with a test light or multimeter:

All fuses checked good

Check the ignition switch for something funky.
