Do all 99 Silverados have the "Turn The Truck off and radio stays on until door opens" thing? If so mine doesnt unless the previous owner turned it off.

 

My truck is a 99 and the radio runs until the door is opened..

 

sounds like someone turned it off.

 

mine doesnt unlock my doors when I put it in park, dealership told me that the origional owner was the one that would have chose this and once it is set it cant be redone, sounds like bs to me but I didnt feel like arguing.
