The wiper fuse is shared by Moon Roof relays, Windshield Washer Motor, Rear Window washer Motor, Integrated Control Unit, Windshield Wiper Motor, Rear Wiper Motor, Power Window relay.
Both fuses should be hot only when ignition switch is turned on therefore there is no reason for them to be the cause. It could be a reverse flow of currect from another source.
At miliamp rates, it should not be a problem.
There are many instances of sticking relays causing parasitic drains as the relay is constantly supplying battery voltage. When the battery terminals are disconnected, the relay opens and problem stops. Under such circumstances, the test would be non conclusive.
Check if the radiator fan or any other components are working when engine is turned off.
