Replaced Fuse 32 to fix diag codes, but then my radio lost power
F150 2004 5.4 Lariat 4WD
I had 5 diag codes that were all listed under fuse 32, so once replacing it, the codes were cleared, and didn't return.
However, then the radio wouldn't power on----totally dark.
I pulled out F31, F1, and F22 and those fuses all look fine.
Any thoughts?
Thanks!

F07 has nothing to do with the radio operating or not. It's in the circuit that disables the audio unit which the ignition switch is in the START position.
You'll need to make voltage checks since the visual didn't reveal anything.
Verify that F31 is ALWAYS HOT and that F22 is HOT when the Accessory Delay Relay is energized (key in RUN or ACCY, through delay timeout period). If the back lights for door lock switch and the roof panel opening switch, if equipped, work then the F22 circuit is okay.
