I have a 2001 Honda Civic and it's mileage is close to 35,000. I was using my air conditioning for about 15 minutes and all of a sudden I smelled some sort of burning smell, almost like burnt rubber. I turned my A/C off and just had the fan run for a minute and the smell went away. I then turned my A/C back on and the smell came back and faint white smoke started coming out of my air vents. I turned the A/C off again and just had the fan running and everything was fine. What is the problem and how do I fix it?
