Hey guys I own a 1986 ford ranger 2.9l v6 and heard what sounded like water chugging out of my dash. I checked and all my fluids are still good and I’m not loosing and fluid below my truck.

A bit of research and it seems to me it’s likely my ac condensation drain in plugged and it’s probably collecting water. I’ve looked everywhere under my truck and can’t find the drain line as well I’ve read my owners manual front to back with no luck…

Can anyone explain to me where the drain line should be or share a photo? Thanks in advance!!!
