Ok so i have a 2000 honda accord ex with the 4-cylinder not v6. So im moving from dyersburg to chattanooga and its about a four hour drive. My car has been doing very well till jsut recently my maintenance required light came on and my air condition blows out white smoke. it doesnt smell or taste like smoke and it only does it when the ac is turned on. What exactly is it and how do i fix it? My thought was that it was just that my ac needed freeon but im not sure about this area in cars. any help would be very appreciated. thanks!

 

Is the a/c still cold?

If it is blowing out "smoke", then it could be simple water vapor. Check that the drain going from the a/c evaporator under the glove box to the firewall in the engine bay is not clogged. That is the hose that drips water when the a/c is on. Just use a pipe cleaner or a hanger to remove any debris in there.
