I've been at this for a while. Since last May. I'm looking for the plastic cam that levers open and closed the cold air door. The part can be seen on the TR7 forum where there is a bunch of discussion on how this part operates. I bumped the post so it should be right at the top. Anyway, if someone has an old heater laying around I would be much obliged if they would post here and let me know. Not too many junk yards in the US Northwest with TR7s lying about.
