Evaporator freezing
Posted: Mon Jul 20, 2026 6:32 am
I have a vintage air system in my 55 Thunderbird. I think the evaporator is freezing because air flow seems to be restricted after running the unit at max cool.
I was trying to get the unit as cold as possible (there are a lot of leaks around my convertible top), I had the thermostat on max, vent temps were 38.
What is the lowest temp at the vents that I should dial in (with thermostat knob) to avoid the freezing?
