AC vent question

[RobD]

Hey guys I was just wondering if someone could answer a question I had. I have a 2017 eagle
355MBQS. The AC vent in the mid bunk room/bonus room only works when the bedroom AC is on. Nothing comes out of that vent when the living room AC is only on. Is this normal or is there an issue with the duct work from living room AC to bonus room ?

We have a 2019 355MBQS. We get airflow from all our vents with either one of our units on. Bunk room air flow was very weak until we did the A/C vent mod. The mod really works to improve the air flow to all the vents.https://www.jaycoowners.com/forums/f...tml#post550147

Thanks for the advice ! I will definitely be doing that mod before next season. I have ZERO airflow in that room with living room AC on but it works with bedroom AC. I’m bringing it in for some warranty work so I’m gonna have them look at it. Since you said it works with either one of your AC’s on I’m thinking it might be a crimped duct.
