Whenever I start my car there is this sound that goes off just before the chimes. It kind of sounds like an air horn, but it'* not loud. It'* not coming from the radio because I turned it off and turned it on. Is this a normal thing or is it telling me that something is wrong?

Where exactly is it coming from? Maybe an old alarm that wasn't proper;y uninstalled?? Maybe just electrical noise going through the speaker wires?

it'* sounds like its coming from the same place the chimes come from when you start the car or when your low on gas.

You start the car
You hear the noise in question
Then you get chimes

Do I have this right?

What are the gagues reading and what are the chimes indicating is wrong?

You have it right. The chimes are just the ones that come on when you start the car. The gauges don't read anything wrong. Everything seems to be working.

If its in cold weather my 90 does that too. Its the air duct / vent lever closing when you start the car. Some are a little tight when its cold and makes an air noise.
