If your vehicle is equipped with AC and you are describing the dash and defroster vents and the 'smoke' isn't harsh on your lungs (if it's electrical smoke, turn off the ignition and disconnect the ground cable of the battery and get a fire extinguisher) it maybe due to the AC Evaporator freezing up and the 'smoke' is akin to the condensation you see when you exhale on a cold day. If the AC evaporator temperature gets below 32degrees F the moisture that is condensing across the evaporator core (cold radiator) freezes; thus the air is laden with cold humidity. An AC tech can usually correct this malfunction quickly if the system is equipped with a cycle switch; other systems may be labor intensive.
why do u want it to stop blowing smoke man! blowing smoke is awsome and manly, and show power! be proud that your blowing smoke!
You can stop your 7.3L from blowing black smoke by verifying that it is burning fuel cleanly and make sure the fuel mix is not too rich. You can also verify that it is not burning any oil.
Check for a vacuum leak -sounds like it is starving for vacuum and reverts to the default position
When there is a problem in the vent system it defaults to defrost setting. Check the doors & vac supply
the smoke that comes out of a exhaust pipe is supposed to be white
Have your injectors checked or changed, burnng to much fuel
White smoke coming from the exhaust is a sign of a bad head gasket. There are some products that you can try for a blown head gasket but they are only good for small leaks. You will probably have to remove the head and replace the head gasket.
you cant stop cloud makers
it means to stop blowing in his ear
If the vents stop blowing when gas is applied, it is likely a vacuum problem. The vent system is controlled by vacuum, so when the engine is under load, there isn't enough vacuum to run the vents. How you test this is when the problem occurs, the fan will still be blowing air, however the flow of air will be out your window defrost vents at the top front of the dash. On a 1995 vehicle, it's likely just some of your vacuum lines are broken, and need replaced or repaired.
white smoke is usually a sign of something wrong coming thru your exhaust pipe.Blown head gasket, transmission fluid etc.
You stop blowing up the world.
