Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
well Melbourne is rarely 5 degrees in the winter time. A mechanic said to me the recharge keeps it lubricated as well and avoids corrosion etc......
I am told by people 'in the trade' that the A/C should be run at least once a week for a few minutes to keep the seals wet and lubricated and to prevent slow leeks.
On some of these new imported cars, the A/C switches on automatically every time the car is driven in reverse, just to ensure the internals are regularly lubricated.
