Volume will not come on radio or cd player but there is power to the radia

Problem with the aerial, no signal being received? Did you clean the back window lately where the aerial is.

Maybe a shorted speaker causing the power amplifier inside the radio to shut down or a speaker wire shorted to chassis and last the internal amplifier of the radio cd set faulty by itself... set volume to zero power it off take out the radio cd set; remove the speaker iso plug leaving the power plug only in and power it on if necesary turn again the volume down to zero and wait if it keeps turned on it a speaker problem if it shut itself off again then you go for a repair or a new one

check your wiring, make sure its not grounded behind the dash somewhere

radio bad

There are 2 fuses to the radio/cd player. #11 and #13. Check them both. If you just got this truck, maybe you don't know you have to push the volume knob to turn it on.

The radio will have to be removed from the car dashboard .
Then please quote the MAKE + MODEL of your radio plus ALL the LETTERS and NUMBERS on any LABELS , BARCODES or STAMPED IN THE METAL CASING.
Also confirm the MAKE of CAR it is fitted into.

if you have installed a new cd player in there then the propblem could be that your speaker wires and either touching each other or grounding them selfs out.. pull of the cd player and check to make sure all the speaker wires are covered properly and no bare wires are exposed.. if you still have a factory cd player in it then you will probably need to take it to a dealership to have it checked out..

Sounds like the head unit is bad. If the truck is under warranty , get it back to the dealership.
