I live in snow country...so experienced the same problem. Book doesn' t tell you how to get the wiper blades to come up, I had to google it and found directions for the 2020 Telluride which is slightly different than for the 2021...but I was able to make it work. Goes something like this: you need to hold down the start button in car and access accessories. Then pull the windshield wiper arm (in the car up)...windshield wipers will come up and stay mid window so you can manually pull away from the window so ice won't freeze the wipers to window (and would also allow you to change blades). If you keep the defrost on high just a couple of minutes window and spray will defrost very fast. To put wipers back where they should sit: manually put them down onto window and then just go in car and when you start car and press window wipers into up position they will go back where they should be. I think it is crazy that I had to google this to find out how to do it. I actually carry around in my car the exact directions in case I forget..
