How replacement windows work, weep holes

We live in Houston and recently replaced our 30-year old windows with vinyl windows. A few of the large, portrait windows leak, and these are getting addressed. The manufacturer has been out, and their "fix" was to take some of the trim off of the inside of the window (inside of the house), and silicone the borders of the window. What they are telling me is that this effectively forces the water back through the frame and out through the weep holes. They are telling me that windows will allow water into the frame and thus, that is the purpose of the weep holes.

My question is for brand new windows, should ANY water get into the frame to be expelled through weep holes? Is this a realistic expectation for new windows? I understand that over the course of time, esp. with the house settling, windows may let water in that get pushed out through the weep holes. But should be that the case right from the factory?

Their "fix" seems to work, but should this fix be what i agree to? Or should I be pushing back to get the windows "fixed" differently?

Thank you. I have spent a significant amount of money on the windows (our house has over 40 windows), and just want to make sure I am getting my money's worth.

Every time we go with window replacement, other than beauty one has to consider the protection and energy efficiency factors too.  Usually, a vinyl window comes with multiple chambers within the frames that feature foam insulation which keeps them air-tight and avoid leaks. They can withstand any extreme climate. They need a good cleaning every once in a while. Good maintenance will ensure long life. Check for few tips at  http://canglow.ca/make-your-vinyl-windows-last-a-lifetime/.

it is quite natural for water to accumulate in the sill and track which is supposed to b drained out via weep holes. Weep hole should be free of dirt. 

Vinyl replacement windows usually are made from the same extrusion on all four sides.  Since the sill is the same-shaped extrusion as the jambs, they need weep holes.

Let me make it simple for you. window tracks that hold the sash when in the vertical position of the frame will collect and hold water since sill is in the bottom horizontal position of the frame. The weep holes help drain the water.
