I have a 1993 Eldo 4.9 (not N*) with what looks like Anti-Freeze and OIL mix? coming out of my floor vent on the passenger side under the dash below the glove box. Today when I started the vehicle I waited till it warmed up. Then I turned on the A/C HI at 60* and it was cooling fine but when I toggled between 60*-90* Holy Smoke!! It was peeing out a stream of what looked like a mix of Anti-Freeze and OIL? through the floor vent on the passenger side. Also smoke was coming out of the Defroster and totally fogged up the (Driver Side ONLY) windshield. Now when I have the A/C on it drips this like oily stuff,and has since permeated the inside of the vehicle with this smell.It used to smell like leather inside. Can any one help??
