Sound System silent when cold
I have a 2004 Tahoe with a 6-CD OEM radio which worked fine all summer. Now that temps are going down to near freezing all of a sudden the entire sound system is dead when I start out in the morning, not a peep. The system is Bose and I don't think it is the radio, because it has power and everything seems to work like normal including the CD player but there is no sound. No FM, no AM, no CD, no nothing. After 2 or 3 hours of driving with the heater on and the car is nice and cozy all of a sudden the sound comes on loud and clear and everything is fine from then on until the next day. I suspect that there may be some corrosion or something like it with some of the Bose amplifier connections which I would like to check but I don't know where GM put that amplifier. Does anybody have any suggestions what could cause this and where the Bose box is?

My bet is that the amp is going bad. I believe it is mounted under the center console between the front seats.

Any of the output amps could be going.

carfiixer, I don't drive that much in a day, maybe 10-15 miles with lots of stops in between and sometimes I don't drive at all for days

Sorry, my failure to be more precise. I meant when I do go in to town I will be out and about for 2-3 hours but with stops in between. It is not continuous driving. The point is that when the car is cold there is no sound. After putzing around for 2-3 hours the sound comes on. At that point the interior of the car is warm has been for about 2-3 hours. What I was trying to say was that it takes 2-3 hours after the car has reached normal operating temps and the inside is nice and cozy because I have the heater turned on that the sound comes back on

I still say the amp is going bad. Replace with a known-good unit and I bet your issue goes away.
. . . or as an alternative: figure a good way to warm the amp up quickly.
. . . joking here, although this would be a good test to verify the amp is bad. If you warm just the amp up while keeping the rest of the cabin cold, and you get instant audio, then you'll know for sure that you found the culprit.

OK looks like that'* what I will do. So you think it is located under the center console between the front seats?? And if it turns out that the amp is bad are these things programmed to the VIN like the radios are or can I try my chances getting a good one from a donor car and it will plug right in and work?
