Now that I have installed the new AC switch I have three fan speeds.  What
I notice though is that in each speed - low-medium-high   iif I rotate the
temperature control to the point where the compressor kicks in I get a
 moderately loud whiring sound - is that the radiator fan kicking in?  And
is it correct that the radiator fan should kick in while the compressor is
on?
