Is it just my TL or do yours do this too? Whenever I drive on the highway maybe 50-60mph, it feels like the vents are blowing out warm air even though my A/C is off. Is this weird?

I also noticed that when I let my car idle, I can hear a fan blowing (coming from the hood, creates an aura of warm air around car)on and off in intervals of maybe 5 min. Is this normal or should I panic?

Both situations are normal. The side vents can be closed with the horizontal wheel lever. also you should press the "recirculate" button on, so the amber light is on, that way it won't allow fresh air from the outside in the cabin through the vents.

the fan operation is normal. honda cars in general do this. sometimes even after the car is off. it is just a cooling fan. totally normal.

phew good to know thanks mike, my car is already in the shop for a new transmission, didn't want it to be there any longer.

Every car I have ever owned has done this; from what I've read it was to keep the air inside the cabin fresh and prevent harmful gases from accumulating due to exhaust leaks, etc.
