I have a VT Berlina wagon which replaced another VT wagon and have had the same problem in both. When the air con
is on and running fine every time I accelerate up hill or have to put my foot down the mode changes from your face to the windscreen and when I ease off it changes back to your face again. This happens every time and had I not blown the engine in the first VT I would have had to get it fixed but it seems strange that the exact same thing is happening again. First car had normal aircon and the current one has climate control. Hope someone can help.
