Hi
I hope someone can help me, I own an Astra Excite 1.4 2015, my aircon seems to be leaking even though it has not been used for a while, I started the car today and ran the aircon on full and water did come out constantly, which I know is normal, but when everything is off, there is a slow drip.

Basically I need to know what do I have to do to stop this

Thanks
Hap
