I have a 2005 Chrysler Sebring Limited Convertible. It is a second car that due to the severe NY winter weather sat for more than a month in our garage. When I went to start it, the battery was dead, so dead that not even interior lights or odometer would illuminate. After fully charging the battery, the car started on the first try, without any problems and ran great. I noticed that the clock had reset and I believe the radio presets were erased when the battery went dead. My problem is that since the battery went dead, my OEM cd changer doesn't work. When I switch the radio to CD, the indicator changes to CD Changer and the radio just says ERR. The lights under each CD button# 1-6 blink all the time. 1-3 blink, then alternate with 4-6. When I first start the car, all of the lights on the changer blink, including the lights for the CD door, then change to the alternating. Don't know if it matters, but I had the car out for several hours this week and I did notice that the number of times the entire changer would blink before switching to alternating would decrease as the day progessed and I started the car more. Do you know what would be causing this? The changer worked flawlessly prior to the battery dying. I would appreciate any help you could give. Thank you.
