Odd Bose radio issues. No sound when cold. Randomly powers off for a few seconds. Occasional theftlock briefly then works fine.

Not that I know of. Just rarely used I guess. I replaced the steering wheel radio control buttons. They were heavily used and some didn’t light up. That was a PITA with the wires being super short.

I replaced my wheel switches.... I removed the steering wheel. It was easier than I thought.

( "1A Auto " video helped a LOT )

Off topic but pretty sure the climate control module was replaced. Everything seems to work fine but it ALWAYS runs the AC compressor. Is that normal on this gen? It’ll be freezing out, I turn up the heat and you hear and feel the ac compressor cycling.

Nope. There is a box bolted to the rear passenger quarter panel with a bunch of connections, license plate lights being one of them. Not sure what the other 3 do…View attachment 411674

Can you take a picture of your rear shocks? or your SPDIF in your glove box? Or Both?

Doesnt appear to have the Z55/Z95 air suspension. So that rules out the Air Suspension Module that are known for corrosion issues.

To explain further, when the corrosion permeates into the module, it can take down, or intermittently take down, the data network. Can create all kinds of hell.

Took the RSE Rear seat audio hvac module out and found some corrosion on the display pins. Cleaned it off and didn’t see any other damage behind display or on the other board.

Reconnected everything and will see if audio still is out next cold morning.

Also cleared all codes again.

42F degrees this am. No door chime. Same issue radio powers on and I can select stations but no sound until it’s on awhile then you hear a pop and audio comes out of all speakers.

Scanned for codes and cycled key a few times. No codes.

When temp doesn’t drop below 50F radio works like it should, sound and door chime immediately.

I would start with a replacement donor radio, but then you are dealing with the theftlock. Sounds like the internal pre-amp has failed. Or whatever sends the signal for the bose amp to turn on.
