No power to the heater controls

I was doing some repairs to the radio, now my blower fan quit working. after doing the usual diagnostics (checked fuses and relays) I discovered there was not power going to the control panel. I don't believe I did anything to the wiring to the ignition switch. help!

For some reason, I can't seem to find a wiring diagram for the truck. At least one that shows the wiring for the controls.
