So mom and dad called me last night. Aparrently the damper fell into their '77 VC defiant. I told them to shut the thermostat down and starve the air so she wouldn't overheat, and that worked fine. now I have to go over and take a look at it for them and see if i can repair it. Anyone have this happen before? What do you think i am gonna find? How does the damper attach to the stove? I am thinking it may be broke in half, but i gotta get over there and see.
