I have a major coolant leak that only seems to happen if I turn the air conditioner on, even for a minute. Why would this happen? If I don't have the air on, there is a minor leak.

Hi there,

The first thing to do is get the cooling system pressure tested and identify where the leak is, have that reverified and see if that fixes your problem.
