How should the aircon fan and radiator fan work?

[runner10]

Yesterday i saw the "overheat" indicator light up in my 2015 Honda City's dashboard. So I immediately pulled over and checked under the hood. Upon my own observation, my radiator & reservoir had enough water. Radiator aux fan was working -- it turned on automatically when it reaches a certain temp. However, I noticed that when I turn on the AC, the aircon aux fan does not turn on. The aircon aux fan should turn on immediately when I turn on the AC, correct or does it only turn on when it reaches a certain temp? Anyway, it did not turn on at all even with the AC turned on for 10mins -- as such, i suspect this was the cause of the overheating.

Is this normal? Should the AC aux fan immediately turn on simultaneously with turning on the AC or does it have to hit a certain temperature before it turns on? Any idea how much to replace AC aux fan motor and the best place to have this replaced na hindi sa Casa???

Thanks in advance mga ka-City for your advise on my problem.

Update:
Turns out both my fans are broken and both need to be replaced.
Aircon shop quoted my 4,000 pesos for 1 Mitsuba aux fan motor with labor na.
So 8,000 pesos for both. Reasonable or mahal?
TIA guys.
