[urq] A/C question

Brandon, I think what Ed describes is most accurate.



Sometimes if a system is low on refrigerant it can draw more power as the raises the system pressure.

On mine, it is noticeable when the a/c is engaged but i wouldn't call it a
vibration per se.  I can feel the engaging/disengaging of the compressor on
the highway too, however the engage event is a very slight sensation as if
briefly passing through a bit of standing water.
