Question about 2011 Jeep Grand Cherokee
Radio has power but no volume
Sounds to me like the radio lost its pass word code.
(or a power amp fuse is blown)
check fuses. , this time. more carefully.
some radios go to now amp mode, will tune but are in pass word mode.
if you drain the battery , this happens everytime.
oldest story in the world this.....
if all power pins on the radio have 12vdc and if radio has external amp
there are like 4 or 5 radio options on new jeeps.
so if it has an external amp,it too has power pins, if they have 12vdc
then the fuse is not blown. (the fsm shows the wiring and fuses, read the FSM)
if the radio is still dead, it can be the radio code issue.
if the fuses are good , its Jeep dealer time.
