You might try lysol spray disinfectant first. Do not use bleach.... it
will ruin metal components. With car ac on at full blast spray into the
vents on outside of car under wipers. You might try it first with ac in
recirculate mode. If that doesn't fix the problem do it in fresh air mode.
Also your dealer may have a foam to use too.
It does have a sickly sweet smelling aspect to it, but it doesn't smell
like coolant. Again, it's something in the area underneath the cowling.
If I pull the cowling off and hit recirc, it doesn't come thru the vents
anymore. If the cowling is on and recirc is on, it still comes through.
Sometimes the airconditioner evaporator drain hose becomes plugges and the
moisture won't drain and mold builds up in the evaporator causeing it to
stink, there is a product sold to kill the smell and mildew,you spray or
squirt it into the vents and the cowl vent. most auto part stores sell it
