Automatic Climate Control Sign of Fatique?

The A/C (retrofitted to R134a) was nice and cold all summer. Now its fall and heat is preferred. Ambient temp: about 62*F. With Smokeless running at normal operating temp (85*-90*C); ACC temp dial set at 22*C; EC button pushed in; Fan speed on AUTO warm air blowing on the side vents fine.

Later on, without any setting change, warm air changed to lukewarm air. Turning temp dial to MAX, no changed. Hmmm. I dont recall the sequence of button-pushing and temp dial turning but somehow I managed to reset the ACC to the above condition.

Something is failing, what may it be?
