Hi Bob, I did that to mine 2 years ago and my ATC still works fine. That seems to be the most common issue which stops the ATC from working in these models.

I was going to try to glue the plastic fittings back on when I got an idea here is what I did. Instead of doing that I took out the unit and removed the cover. Then I numbered all the hoses and the same ones on the plugs that go on the fitting. Then I removed the hoses out of the rubber grommets that held the hoses. Then I used new vacuum connectors and reattached the vacuum lines. And now I do not have any lines that are unhooked. As soon as I get the valve covers back on and restart the engine I will let you know if this fix worked and if my heater works again. Bob 68 Imperial convertible
