Hi All!

I few months ago I noticed the lever to switch between fresh air and recirculate was getting harder and harder to move. If I put enough pressure on it eventually it would fly over to the other position very quickly. Then one day the lever broke. So I need a temp control panel. Here's my question: the cable that attaches to that lever... what does the other end connect to? I would imagine some sort of box with a flap in it to redirect the air. But after hours of looking online I'm unable to find what that part is called or where to get one. Any thoughts? THanks!
