The Stovebolt Site Forums The Shop Area Interiors Fresh air heater question: Defrost vent flap

My question: Which direction does the lever move for "defrost"? Right or left?

I just installed an original one this spring and haven't hooked up the defroster cable, generally I keep it on defrost as its always humid here. This summer though I threw the valve open to get the cool air on the floor, without thinking much of it.

Now I need defrost again in the mornings. There is a sticky point with it I had to push it past; and now whether I move the lever forward or back, I can't see much of anything for air coming out of the defrost ducts. Putting some light paper over the defrost ducts didn't make any noticeable difference just now. Yes the vents are hooked up at both ends! I put a pen up inside and can feel the flap moving with the lever, so that's technically working.

So I'm asking this question to make sure I'm messing around with it in the right direction to start.

Thanks!!!
