Odd electrical issue
 

I was told by the previous owner that the radio worked but the cruise control didn't. Then one day something happened and the radio stopped working, but the cruise started working. Ever since I've owned it, the factory radio hasn't worked. I took it to Ford to diagnose it and they said it's getting power--bad radio. So I bought a radio online and am anxiously awaiting it's arrival. In preparation, I took out the old radio and noticed today while I was driving that the cruise control dash light works now. It stopped working back when the radio and cruise flip flopped which one was working.

So, to sum up, no radio and the dash cruise control light works. I have to see what happens when I put in the new radio, but if there's an underlying electrical issue, I'm hesitant. Could the old radio just be screwed and it was messing up other things? Electricity issues?

Anyone have any ideas?

Need the year of the Ranger?

Oh, sorry. 2001 XLT regular cab.

Not seeing a connection on the 12volt side of things in 2001 diagram

Fuse 20 in cab fuse box(key on power) shows Audio Unit
Fuse 28 in cab fuse box is also hooked to radio but..................it is a MUTE feature, it only has 12volts when key is in START position, this should cause radio audio to shut off

Fuse 10 in cab fuse box(key on power) shows Speed control servo

all 3 are 7.5amp
And they are not on the same ignition switch bus/wire

The radio and cruise don't share a ground point

Thanks. I installed my new radio and all seems good. Cruise works, my radio works, and the cruise light works. It must have been something with the old busted factory radio...
