if there are no leaks...i would say it is electrical. check the relay.

The leaks may be small. some of the areas where the leaks occur are not very accessible, i.e. behind the radiator, and in the cabin.

I have a slow leak that happens to discharge after a year or two. its annoying but they couldnt find the leak.
