I’m getting blasts of coolant through the HVAC from time to time. Not loving it, as it makes me tired and my vision go funky. Pretty sure its either getting drawn in from the outside vent (though I can’t see a place it would be leaking) or its a cracked heater core (woo hoo!).
The good news is that I have a totally independent heater core under the passenger seat that I can turn on to heat the car...but its not as powerful and takes a while to do its thing.
Really hoping it’s just a minor underhood leak that is being drawn into the intake and I don’t have to do this.
