2002 Deville Base

1. Battery went dead due to light being on
2. Removed battery and charged. reinstalled. Shows proper voltage
3. Car started up and runs fine.
4. No radio. Getting power. Fuses ok. No station display or sound.
5. Security, traction, air bag, and battery light on dash all stay on.
6. Get coolant warning , oil change warning, ect. Checked and no problems with levels etc.
7. Key fob stopped working. Changed battery. still not working.
8. Everything else seems to work.

Only current code is IPC U1000 which I assume is due to radio not working.

Any help in getting radio working, lights off, and fob working?

 

I should mention that battery is probably 5 years old. Maybe due for changing even thought voltage remains good and no problem turning over?

 

ast thing... After I charged battery and reinstalled, the battery died again. I checked all lights and nothing on. I checked draw on battery by pulling fuses and found the radio to being the parasite. After pulling fuse, battery did not die again after that.
