Why do I get a strong antifreeze smell when I run the AC?

Thanks for your response. The floorboards are dry. Do you have any other ideas on what it may be? I see no leaks anywhere.

maybe is only leaking under pressure. have the cooling system oressure tested when eng is warm

Same with me...nothing was obvious. I ended up replacing the radiator, it had a small pin hole leak in it that was not detectable when I looked it over. The smell is gone now. You can try this but it may not fix your problem if it's not the radiator. Good Luck!
