The handle which actuates the cowl vent on my 54 cab will not budge. Must have been installed by a union negotiator. I have disconnected the arms to determine if it is the top portion or the bottom portion that is inoperable and have have confirmed the bottom is the problem.
How is this supposed to function? Pull up-push down - turn it all around? If you had this problem how did you solve it other than sealing the vent? I think the vent is cool and would like to retain it.
