No heat from living room heat ducts?
It might just be this. Photo taken under the floor vent of the mid bathroom on a 2016 39MB with a borescope I bought on Amazon.
1) Check out the wood shavings still lying on floor of the duct from drilling through bathroom floor to install vent.
2) I wondered why the basement was much warmer than our living room, check out the duct tape flashing job where the bathroom heat vent attaches to the duct.
