I have a problem with my 2004 Ford Ranger that just started today.

The radio is getting power when the ignition is in both the accessory & the run positions.


The problem: There is only radio volume when the ignition is in the on position but only when the motor is not running.

Accessory position = NO radio volume
Motor running = NO radio volume
Ignition on/motor not running = radio volume works


Any ideas what may be the cause of this strangeness?


Thanks

 

Welcome to the forum


Doesn't sound to hard, you probably have a separate amplifier.

Have a look here: Ford Ranger Radio Wiring Diagram

Look at the 2004 Premium sound system
The separate amp should have power all the time but turned on and off by radio on/off.
"Enable"

As another may be, Ford added a MUTE circuit for Radios in late 1990's/early 2000's
Have a read here: http://www.justanswer.com/ford/2ecz3...ve-revers.html

It's for people who forgot to turn the radio volume down after driving home drunk the night before.......................joking

 

got in my 2004 Ranger this morning and the radio volume works in all three scenarios now


I however have a suspicion this issue isn't over yet ............

 

found this thread from late 2014; sounds like the same issue
