how AC clutch cycles? AC thermostat checking?

Sorry,  I meant "too high".  I expected to see 38F.  It gets to 50F in 2-3 min.
It stays there for another 10 min I tested.
Radiator shroud is in place but there are some cracks and gaps in it.  I will try
to close them and see how it affects perfomance.

I missed original post in the recent thread about temp sensor cranking to affect
clutch duty cycle.
What sensor is it and where is it located?  I thought that only thing which
affects duty cycle is thermostat located next to evaporator
(with thermocouple inserted inside evaporator).
Today morning I again did not see cycling after 10 min of A/C working.  Yesterday
morning I saw it in  3 minutes after turning on the car.
Anything beside thermostat can affect it?

Thanks.
Konstantin.
