Not much info online to change the shutter assembly for my 2015 Murano Platinum except from the aforementioned manuals. I printed off the ext. sections and attempted the repair myself. Many, many pushpins along with a few screws and bolts. Started at the top and pulled the guides above the radiator, then pulled the grill along with disconnecting the camera, then pulled the bumper cover by partially removing the outer wheel trim, then removing the pushpins and bolts underneath the front spoiler, (not removing the spoiler), then unsnaping each side of the bumper cover from the fender and 2 pushpins on top of the bumper cover. After removing the bumper cover, I was able to change out the shutter assembly without removing the bumper, just 1-10mm bolt on each side and 2 pushpins. Once changed, I started the vehicle with the shutter in the closed position and it worked fine. I then re-attached everything in the reverse order. After about 10 miles and 2-3 starts later, the CEL light went off. And yes, you could just change the actuator by itself, but I decided to change out the whole assembly. Thanks for all of the input from the community!
