The only circuit that all three of those items runs through is the ignition switch. You can test it as follows. You will need a multi-meter.

Test for 12 V at the HTR-A/C fuse, #12, with the key on.

Test for 12 V from the ignition switch, pin C6 Orange wire at the column connector, key on.

If low at the Orange wire also, replace the ignition switch.
