When my ac is set to lo, the wind is sometimes warm like 70ish. When it's set to 75+, it's sometimes cold like in the 50s. It's not always the case but enough times that it makes me wonder if there's something wrong with the ac. The dealer says "don't look at the number. Just adjust it what's comfortable for you." Although that's what I do since I can't rely on the number but it's not supposed to work that way.
