Intermittent radio CD, etc. every 20 - 30 seconds the sound drops out and then resets itself. It is like the power is shut off and then is restored.

loose battery terminal or ground wire m

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

Try disconnecting the battery, wait about 15 seconds and reconnect the cable. It may reset the radio.

is it an after market radio? if so it might not have enough power so it goes to pull power when its turned up and its not there so it just shuts off. try checking your radio wires and your fuse.

Take the radio out and remove the coins is the first thing i would advise

there is a fuse in fuse box that powers radio...sounds like a problem with radio itself....if fuse was bad it simply would do nothing"no power at all.

The problem sounds like intermittent power supply. There might be an inline fuse which sometimes does cause problems. Remove the radio and check the power line to see if there is such a fuse. If so, remove and clean it with a bit of sandpaper, put it all together and see if it helps.
Sorry, can't be more helpful.

i have the same truck and had the same problem, finally found a mechanic that found the problem. under the console (cd player) was a loose wire, he sautered it, has been great since.

Chrysler issued a Service Bulletin on this issue:

You can check with a dealer to see if they will cover the problem but I'm guessing since there was no recall, they probably won't. If not, you can try this:

Reset the radio by disconnecting the negative battery cable for 10 mins or so. After you reconnect, the radio should reset and resolve your issue.

I hope this fixes your problem. Best of luck!

Turn off the car and remove the negative battery cable off. let sit a few minutes then reconnect the cable. try it several times. The removal of the battery causes the computer to deprogram itself. what you will be doing is re-programming the computer module.
