The switched 12v wire to my radio is not working on my 2001 escape.
The non-switched 12v wire is, but without the switched wire, the radio will not work. Any ideas as to what could be causing this? where does the switched wire come from. I am unable to trace it back because it goes into
a big taped bundle of wires. Is there any sort of relay or some other item
that could be bad? The power windows work when the ignitiion is in the ACC position, so the ignition can be complete bad. What could it be? How do I trouble shoot this?

Thanks
