Hmm... now that I think about it some more, I wonder about the "AC" function. Multiple people have said it should just be kept on at all times, even during winter, I guess for its dehumidifying properties.
But doesn't that mean you're running the AC compressor at all times, which might lead to it giving out earlier.
On my previous cars, none of which had automatic climate control, I only ever turned the AC on during the warmer months.
What are people's opinions on whether to leave AC on all year long?
