The air pressure forced the foam pieces to come out of each vent. I did this over a year ago and have had only a couple of small pieces come out since. I may need to do this again at some point, depending on how much foam was left behind and when it deteriorates.

What pity this does not work well ! Particlewave explained why .
But suppose you install a simple,direct,hand operated valve on the hot coolant inlet hose to the heater core .That would prevent warming of the a/c air. Anyone tried this? Where is the best location for such a valve ? It should be simple to just use a Home Depot valve with a hose barb at each side.
This one even has some bling ! Would tke 20 mins max to do
SharkBite 3/8 in. Chrome-Plated Brass PEX Barb Quarter-Turn Straight Stop-23382LF - The Home Depot
or search AmaZon for "3/8 barb x barb valve" Maybe 1/2" is the correct size? It is easy to just rummage at H.D.Plumbing Dept with a sample of your heater hose in hand and get separate barb fittings to connect to a standard,straight brass valve.
If this would work it would be a good interim fix because the procedures described above would take many hours of careful work.
While you are in there jobs? - the horn ring fix !
Feel free to improve on the suggestion
