When I click on that link it says "sorry, a window sticker is not available for this VIN.
It doesn't even give me the opportunity to insert my VIN #.
That is correct. But if you then enter your vin after the = sign it works. If no window sticker is available yet you will get the same message as with the empty VIN. Otherwise the window sticker itself will open. I have the VINs for two trucks. One shows me the window sticker, the other still says not available.
As Will_T said, add your VIN in the URL after the vin= as shown,
