The radio light in my 2001 Rodeo went out totally about 2 weeks ago. I left my headlights on one night and my husband put the battery on a charger for me. Now the radio light is on ALL THE TIME - even with the car shut off! This can't be good... Any advice would be appreciated.

is this the factory radio

Yes - sorry - it is a factory installed radio w/cassette player.

No clue. Time to upgrade to a non-stock radio....

do you have a trailer harness?
