great help thanks a lot mate.andrew Just had my KeepKool engineer to re gas my MK1, 1997, 2.3 Galaxy, used him several times and he's been great, but he can't fit it this time, pressure and gas is fine, but air con cuts in and cools to 6C then turns itself off when the car is still very warm then warms up, he thinks it could be a sticky relay as its intermittent, Haynes Manuel and Owner's Guide not a lot good regarding fuses and relays as they don't compare with what i've got. Any ideas. Patch
