I purchased a 2016 ex-l in oct. it's build date was sept. Everything about the hvac system works perfectly, air flow is perfect except there is zero air coming from the passenger vent no matter what setting.

My speculation is that either there is a plastic film or part during original manufacture that was not removed, or that something fell or was put in the vent and wasn't removed from it.

Does anyone know how to remove the vent cover for the passenger side so i can probe down into it?

Also, is the duct vent assembly one continuous piece or is it pieced together? I can't tell from the schematic. 77420-T5R-A01 is the part number.

My dealer is an hour away, I'd rather just unclog the vent myself.

 

Try removing your glove box door and see if you can gain access that way.

And I know this is an "obvious" thing to ask, but you did check to make sure the vent is set to "open," right? (c:

I unhinged the glovebox, but haven't yet taken it completely off to get a better look at things.

Yeah, I opened and closed the vent with no effect. Even with the vent closed on every other car i've had, there is always a little residual air flow. Here, there is nothing, not even residual air flow.

It really seems like the only possibility is some kind of foam packing left in the ductwork from when they were putting the car together....
