I have a 2006 Avalanche Z71. When I start the truck I get a couple normal door chime sounds but then I get a fast paced chime that dings about 35 times. It’s playing through my speakers like the normal one. Can anyone explain why my truck is doing it? It lasts for at least 10-15 seconds every time I start the truck. I tried looking on the forums but all I couldn’t find a solution.
