I've noticed that my A/C is not one smooth and consistent flow of air but fluctuates the flow that is coming out of the vents from faster to slower on it's own. My loaner XF which I assume has the same system runs flawlessly. Anyone else experience this on their XK?

 

I thought the climate control system was supposed to do this?

 

I'm referring to the fan speed continually going up and down up and down. I'm not talking about the speed of the fan changing to a higher speed for different temperatures.
