Weird Noice In My '03 Ls430


Recommended Posts

This August when I bought my CPO 430 and I was driving it back from Ann Arbor to Nashville and had the A/C on the entire trip. Around 100 miles into the trip I noticed when I had the radio off I heard a "swishing" or a "psssst" sound that seemed to be coming from my driver's side A/C vent. When I turned the A/C off it went away. I took it to my dealer when I was getting the oil changed and naturally I could not duplicate that noise but I do still have it when I use the A/C. I am not real worried since it's a CPO car and will get it addressed in the near future but could it be water dripping or condensation in the A/C vents?
