Ok, here’s the thing.
Miserable day in Bath, rain hammering down when I went to work this morning. Windscreen started misting up. So I turn the fan on, as you do. A nasty, eggy/cheesy smell envelopes the car - not so bad that I gag, but enough to make me think that breathing isn’t always a good option. Mist increases. So I turn the fan up - to Point 4 - the top, thinking that there must be an obstruction. Then it happens. A noxious green liquid starts spitting out of the fan up against the windscreen and fountains down onto the steering wheel. I turn fan off and squint the next three miles to work, holding my breath (ok slight exaggeration but you get my point).
So dopers - what’s happening to my car. I’m thinking it’s probably not good so don’t spare me! By the way, it’s a Renault Laguna 2.0RT.
