XC90 roof motor replacement

2.6k for Volvo to replace it🫠 u guys think this is a doable job by a regular ass dude with average car knowledge?? What about that VCM backup battery?? I’m new to Volvo so not sure how involved a battery replacement would be?? But I feel like I could totally do that battery for way less then 500 bucks
