Beeeeep vs beep-beep

My question falls into the "what does it really matter" category. Even so, it has piqued my curiosity.

When I first picked up my 2006 3500 cargo van in June it would sound a continuous Beeeep when in reverse. Just today it started doing the beep-beep-beep that we normally associate with such vehicles when they're being backed up. Is the beeping controlled by a relay (or what) and does anyone know where the controlling unit would be found?

Thanks!

As nobody else has chimed in (pun intended), I'm 99.99% certain the beep timing is integral with the plug in backup alarm unit. It just needs 12V. from the back up lights to get it beeping. Hope this helps.

i would have to agree with you there.

Thanks! When the weather warms up I'll have to crawl under and take a look at the beeper. If it quits maybe I can get something from a novelty store that makes laughing noises or something

Happy new year!
