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.

After further research, turns out the 30 amp fuse under hood was toast. Replaced it, got power to the pannel. Checked the fan for power, had it there. Tapped on the motor, now it works. Go figure!
