Power folding mirrors.
 

I have a 2004 Silverado 2500HD with power folding, heated and built in turn signals mirrors. Is this considered the DL3 mirror. I am looking to remove and replace with power vision model #6141T. But before I buy I need to know if I have the DL3 style on there now because if so, then I am going to have to get the door module reflashed. I'm just not sure.
