2003 Jeep Liberty - no radio sound after replacing the battery

Sounds like a ground problem allowing a back feed issue.

Make sure your battery is grounded to the engine and frame.

the alternator charges the battery so if that happens then your alternator is bad but if you jump it and it works for sometime then i guess ur battery is bad so change the battery

is it a factory radio??? if it aftermarket radio could be loose conection on one of wires but sounds more like the radio has a short inside the radio it self you probley have to replace the radio

SOUND LIKE DEAD BATTERY.CHECK BATTERY CABLE FOR TIGHTNESS AND FREE FROM CORROSSION AT BATTERY POST AND BATTERY CABLES.MAKE SURE BATTERY VOLTAGE IS 12.5 VOLTS.IF NOT BATTERY NEED CHARGING AND TESTED.IF BATTERY GOOD.SOUND LIKE ALTERNATOR BAD.BEFORE REPLACING OR DISCONNECTING BATTERY CABLES OR BATTERY AND ALTERNATOR.TURN OFF RADIO SO YOU WONT LOSE PLAYING CODE.

You heater only works on speeds #2 & 4 because the blower motor resistor pack is defective. Replace it.

check your wiring connection and if the gauge goes back to normal when radio is unplugged then get a different source of power to the radio.This should solve.

try using canned air to clean

Yea i had the same exact year liberty and the same 6 cd player...chrysler cd players just straight up ****...i would just replace the cd player...it probly shot...and if not...you should anyways because its just gunna be one problem after another.

sometimes the cd player optic eye inside is broken and is not able to read the disks. try another cd player or check the wiring behind it ok?

Oops! Should mention I have 2004 Jeep Grand Cherokee, not Liberty.
