Firstly apoligies to staz!!!
ill try to explain the problem better
my air con doesnt work, i took the car to an air con specialist to have it re gassed.
he put a gauge on one of the pipes which read danger too much pressure (i think)
he let some pressure go but it kept increasing on its own going back into the danger area on his gauge
i was told the fault lay with the fact the air con compressor is stuck on all the time causing the pressure increase
i dont have a econ button on my climate control
the result of above was i got told the increasing pressure was shutting the aircon down
does any of this sound right or make sence to anyone
