Bullseye54 10-20-2004, 01:46 PM Since I bought my 3500 used last year I've been trying to get rid of the nicotene smell out of the a/c ducting.The prev owner was a chain smoker.When you get in the truck after sitting a day or two in the heat & turn on a/c it almost makes you puke. I've changed the filters & sprayed all kinds of disinfectants & odor killers in the ducting,still stinks.Anyone have any ideas besides taking up smoking? WAskier 10-20-2004, 06:10 PM I can't believe that the only thing that stinks is the Ducting. Does the carpet and upolstery really not smell? Anyway, my buddy bought a car from a guy who smoked and he took it to a detail shop where they were able to run a ozone unit in his car and sprayed some stuff in it and it helped a lot. I dunno if that'll work for you since it's in the ducting but it's something to look into. Max Owner 10-21-2004, 12:14 AM If the A/C is used on recirculate, where is the intake for the air? Down near the floor? Maybe try cleaning the intake tube? A shot in the dark.

Probably what it's going to take, when you get to the evaporator any HVAC supply house will have the cleaner required to safely clean that.
