This is normal. Compressor will cycle in order to dry the air out otherwise you will create plenty of moisture from introducing heat alone (i.e. fogged windows) in the cab.

Typically you notice this when you run the defrost option. The default on the defrost selection will engage the a/c compressor in order to dehumidify the air and assist in removing the fog from glass.
