ACC malfunction

Greetings from Finland, folks! I’m wondering if someone has seen this kind of malfunction in ACC system: I have a ’85 9000 turbo16 (manual gearbox). I had slightly modified engine in it until last winter it broke. So we changed the engine and we also changed the cabin heater core at the same time as it appeared to leak a bit. That was when the problems begun.
When outside temperature is below freezing point, the ACC keeps the airflow in “windshield defog” and fan speed 2 on all the time. Doesn’t matter how hot the water or cabin is. Manual control works, so the actuators are OK. When the outside temperature is above freezing point but not too hot, ACC starts to control the actuators after long wait. Or if I stop the engine after 10 miles drive or so and restart it, the ACC works immediately. At summertime when the air is warm, there is no problem.
I tried to run ACC selftest and when blinking “88” disappeared, there was “0” on the display. Does somebody know what might cause this? All tips are appreciated!
