1992 Silverado, 305...150,000 miles. Switched on AC the other day, and it did not get cold. The "AC" led was blinking, I assume indicating it was in distress of some sort. Ive had the truck 4 years, cold AC every summer, but now I guess thats out the window. Anyway...I started smelling freon in the cab and when I opened the hood, I again smelled it. You cant miss that smell, it stinks bad. Besides repairing, besides refilling, what can I do stop the the smell? It cant be good to breath this stuff. Truck got "totaled" by ins. compnay last week, but runs and drives, so its hardly worth putting any real bucks into it. Thanks.
