warning light?
When the light comes on, and if the radio is on, the volume is muted, but the radio stays on. The heat/ac control lights go out. When the warning light goes away, the sound comes back and the heat/ac control lights come back on.
One job the mechanic did on this car was replace the alternator. When the wife was first driving it after we picked it up, the brake light, abs light and battery light would come on as well as the volume on the radio muted. After hooking the car up to a multimeter, the alternator ranges from 12.4 volts to around 17 volts. When it goes high is when the radio goes silent but this warning light in the center display wasn't there before.
This is what the light looks like. The car is running, multimeter shows 17 volts at the battery, no radio volume and heat/ac control lights are out. I don't see anything in the manual or anywhere else that looks like this, even though some pixels are out.
