Air conditioning

["Graham WELLS" <gwells@xxxx>]

A small problem has appeared. The aircon works beautifully with the car
stationary, and blows nice cool air whether you rev the engine or if it
is at idle. When you are driving, however, cool air flows nicely but
when you accelerate, the cool air becomes warmer, and when you
decelerate the air goes cool again. I thought at first that it might be
a vacuum problem, i.e. when accelerating, vacuum obviously decreases,
and if there were a leak then it might have an effect on the flap
positions. However it appears to be more related to vehicle movement.
Might it need regassing? It cycles regularily as one would expect with
no indications of being low in gas.
Any ideas?
