Air con evaporator drain

[Mattyjones]

Hi I’m after a bit of help please…this past weekend while on a trip up to Scotland I had the air con on and noticed water dripping (at times a steady stream of water ) down from the centre console and into the drivers foot well. After a little research I believe this could be a blocked evaporator drain. I’m struggling to find online or while checking the van where the drain is located to try and unblock.
Has anyone ever experienced this issue and managed to solve?
Appreciate any help or pointers?
Thanks
