There are two in the front that run down the A-pillars. The holes are a bit difficult to see, but they're in the front corners. There probably are two more in the back that run down the B-Pillars, as well.
Literally just had ours leak a couple days ago, and I ended up having to blow the passenger front side one out with my air compressor attached to some vacuum hose I had shoved down the tube.
