basicaly ive only had one car before with air con, on the way back from pvs on sunday, put on the air con, nothing happend not working. with the car i had before when on tick over, put on air con and engine dropped a few revs and you could hear the air con kick in. do the same with the vectra, nothing. ive only had the car four months, and its 3 years old on the 15th this month. so managed to get booked in for 12th, they say it just needs regasing, but i think its more involved than that, anyone else had this, plus whats coverd on the warenty, they dont seem to want to do it.
