Today, I was out washing and detailing my car. After the wash, I had all four doors & trunk open for cleaning and conditioning the leather. In about two hours, there was a beep I looked at the front dash and my airbag light turned on. Next a strange rapid clicking noise came from under the hood, which lasted maybe 5-10 seconds. It kept doing that for the next few minutes. Anyone with issues similar to this?

 

Two hours with the doors and trunk open... was the light on? I could see a low battery causing this.
