R model cowl vent

[BulldogMack]

So my r model project is almost complete. Down to buttoning up a little bit of this and a little bit of that. This things been both a dream, and a headache. But it’s gonna be worth it. 
Anyways. I bought a new cowl bent as my other one was brittle and broken and the hinge had seized. When I brought the truck home, the vent was disconnected already. Nonetheless, I hooked up the linkage, and aired the truck up to check my cab ride height. Looks good. When I slide the switch over, it clicks, makes the “door” of the vent budge a small bit, and that’s it. I decided to call it a night. I am seeking knowledge from the Mack community on what to look for, after I get out of work tomorrow. I’ll unhook it to start and see if the linkage moves. To be fair I don’t know how these work, and am absolutely willing to learn. Thank you, and i appreciate the future advice! God Bless.

I'm thinking a squirt of normal engine oil would help a lot as the seal is probably dry as chips

Paul, I replace the seal, and the unit is entirely brand new. The hinge itself moved what I’d considered normal, but I will try to lube it up real good tomorrow. I’ll double check as well and make sure it’s not all bound up. 
If I am hearing some sort of function from the driver seat when I move the switch, would that indicate everything under the dash is working properly, and potentially the vent itself is bound up?
