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? Graham Wells VIN 17152
