2002 Eldorado Bose

I've searched and found nothing definitive, so thought I'd ask again.

If car sits for 2-3 days without starting the radio will not 'turn on', no display, antenna is not powering up, no sound, no controls. Clock display works all the time. Radio is not losing presets when i disconnect ground.

If I disconnect ground at battery (as had been commented on in several posts), it 'clears' and works perfectly, antenna powers up, etc.

While I can't say with 100% certainty, I THINK I can say that if I drive car every day it doesn't recreate.

But I can't get out and disconnect battery every time I want to play radio. Something isn't 'right'.

It has the 12 disc changer, and I've just removed the cartridge to see if the Changer is somehow or another trying to read the discs or somehow draining battery. But no result to report on that one yet.

I'm not getting a theft/lock code or anything like that.

I haven't had the car very long, so I don't know how old the battery is, but I doubt a few days drain would affect the radio coming or, nor would disconnecting ground 'restore' the battery per se. I assume it has to be a module issue? Or at least something that has to be 'rebooted/cleared'. But that's just a guess.

No current codes. History had a low battery volt code and one EEPROM memory, but don't know how old they were. I'm also going to pick up a multimeter that has right settings to test if there is any battery drain going on.

I didn't know if anyone has seen anything like this before. I can keep chasing, but would like to avoid too many goose chases if someone has some direction for me.

Thanks for any insights.

I have the same issue on my 03 Seville STS.

For some reason, the screen works, the touch screen works but the sound works about 1 on 3 times ...

And when I play with the DSP, the sound appears for half a sec when I touch the preset and dies.

I've got similar issues with a Bose unit in my '99 STS. Radio lights up, station selection displays, but no sound.
I'm thinking it maybe in the amp behind the rear seat. I just don't have the energy to remove the back of the rear seat (PITA).
Havn't tried disconnecting the battery

I had a problem last summer with my 98 ETC. My battery went dead in storage and when I replaced the battery, I had no sound on the radio.

The fix was to remove both the pos and neg leads from the battery and short them together or hold the pos lead to the neg lead. I did this for
about a minute, then put them back on the battery. When the car started up, the radio was back to normal.
The dealership suggested I do this and my mechanic could not believe it worked, LOL. I WAS TICKLED PINK ! ! !!

I too had the same problem with the radio on my 2001 Eldorado. I did that holding the battery cables together trick and also replaced the 12-Disc CD Changer in the trunk b/c it was not working properly. The issue is now resolved.

I can’t be sure which solution actually fixed the problem since the radio not working was intermittent. I did the cable trick and replaced the CD Changer relatively close in time so I’m not exactly sure which specific solution did the trick.

Hello fellow radio guys. I have a similar problem on my 1984 Eldorado. I installed and aftermarket Kenwood with a 900 watt amplifier and sub woofers. Everything worked fine for about 8 years then recently it started cutting out. Total loss of power so it would power down then a minute later come back on. I checked all the connectors to make sure there were no bad connections, with no results. So I got under the dash to inspect the fuse box. Lo and behold the 10 amp fuse was blown. One of those fuses that lights up when it blows. High tech. Anyway, I was elated and knew this was the problem. I replaced the fuse and tried it out. Same thing happens. What I don't understand is how the whole system worked with a blown fuse. For me a blown fuse means no power. But with the first fuse it worked intermittently. I guess I'll try the cable trick to see what happens but from an electrical point of view I'm still baffled how it was working. With the new fuse installed everything dies when I remove it. Any ideas would be appreciated. Thanks, Big Bird
