Good Morning All,

I have a 2011 Cyclone 3950 HD and can't figure out how the roof vent over the garage got opened. I can't find a button to push inside and don't remember opening it in the first place. Is there some magic button inside to open and close the vent. I have the side vents opened but can't figure out how in the hect that vent was opened. TIA for any assistance.
