Loss of interior audio in cold weather

[Mathew Kirsch]

2015 Silverado 1500, 120,000 miles.

 

When the temperature gets below 25F, and the headlights are on, and the heater fan is on, and the radio is on, when I pulse the windshield wipers, I lose all interior audio.

 

No radio. No blinkers. No warning chimes. Nothing.

 

Turning the radio off and on, even REALLY turning it off and on, does nothing. The only way to get audio back is to park the truck, shut it off, get out, walk away for 10 minutes, and come back. After that everything is fine again until the next time it happens.

 

It has done this since the truck was new.

 

Dealers want nothing to do with it. Couldn't reproduce it, no fault found. Talked to a service manager here recently about it. He put his hands in his pockets, looked at the ground, poked at an imaginary rock with his toe, and said, "Welll uh, I've never heard of such a thing, and uh, it sounds electrical, wiring... You could spend thousands hunting down a wiring problem like that..."

I have a 2015 Sierra and just recently I’ve had a similar experience. I get in the truck and put the key in and no bells. Start the truck no radio, no blinker noise. Saw another thread that mentioned a low battery voltage issue. Can’t figure it, shut the truck off for ten minutes and everything comes back.

Welcome to the site.

 

If you still have the original battery. replace it, they do not last very long with the draw that is put on them by the truck.
