Help!!!

[StinkinLinkinLS01]

I recently added a KKM filter to my LS and am currently working on a RAM air style mod as well as the heat shield. Now I'm obviously sucking in a lot of hot air but as of late my A/C has begun to blow out hot air through some, not all, of the vents. Mainly the two middle vents. My question is whether or not this anything to do with my neww filter taking in too much hot air or is it just a general malfunction. Basically, has anyone else had this problem and what is that you have found out? Thanks in advance.

Considering that the air that comes in through the intake goes out through the exhaust, I'd say the chances of it being a coincidence are really high.

I think I've seen this mentioned somewhere on an LS forum, but I couldn't swear to that. You might try searching for "blend door" or something similar.
