My '95 Town Car suddenly stopped cooling in mid-July last year. The idea of using the vents to blow air in didn’t work either-- just hot air. And the heater only knows two words-- hot and off. The clutch seems ok, the coolant is ok, the relay works, the fan works-- does it have a control module somewhere between the spleen and pancreas that may have seized? I know SOMETHING had to operate the different doors here and there… but doesn’t anymore.
