My 07 Silvie LTZ does not have the DL8 code.....But it does have a DK8 code...So how would I know if my mirrors are heated?...I just bought it this past June,so I really haven't noticed if they are or not heated..
A quick way to do it is look for the code DL8 or push the button on the climate control for the defrost which will look like a mirror with waves running through it and with the truck running feel the mirror after about 5 to 10 mins of running and see if it's warm at all.
It could also be code DL3, do your mirrors have the signals in them. I have those on mine and the mirror code is DL3.
DL3 mirrors are also power folding.
In my case I have DL3 which are heated power folding mirrors with integrated turn signals, and a power sliding rear window without a defroster. The control for the rear window is on the overhead console, mirror heat is on the HVAC control panel, and mirror folding button is on the drivers' door right above the power lock buttons.
