That is just the nature of a/c. If you run the a/c in your car on low fan, the air coming out of the vents will be cooler, as it will have more time at the evaporator to absorb the cold.
The "throb" is a sympathetic vibration (oscillation) of the fan at a higher speed.

thanks Terry...i feel better about this...thought my ac was failing...looks like low cool with an exterior fan is a good idea....i'm adding another ac to the front area of the roof of the mh to run while driving down the road (no dash ac)...joe
