I am leaving for a weekend at the lake for Labor Day weekend and we are bringing out 2 1/2 month old baby with us for the first time.

Last time out, I realized that the air in the main cabin was barely blowing, but all other vents were doing great.

After looking in the main cabin vent, I noticed that the duct was off of the coupler that holds it to the vent.

I just spent 2 hours trying to get that vent cover off. I can not get to the back of it, and I think that on both sides there are grooves that hold it in place making it impossible to come out from the front side.

I can't find 1 access point that I could actually reach and attempt to fix this issue. Does anyone have a trick to this? My boat will not cool down without the largest duct delivering cold air and I need it. It has been 110+ degrees and looks like 107-108 for the weekend.


Here is a picture of the vent.

Thanks!!!

maybe you need to pull out what loosk like the TV to get behind there? i dunno....any other items that you can yank to get behind there?

No. You can see the duct going through the wall, but there is no way to get your hand/arm though the hole that is way back there, then bend your arm forward to work on the vent.

I dont see how your arm could bend like that.

if it is the same as the fastech which it looks like there should be 4 plastic clips that you slide about a 1/2" with a small pocket screwdriver 2 on top and bottom . that should be the return grill not a supply.

No, the return grill is much bigger and on the front of a cabinet where the A/C is.
