Leaking sliding glass door

Last summer I put in a sliding glass door leading from the dining room out to the deck. I put down silicone, then a piece of pressure treated 1/2" board to act as a 'sill plate', then more silicone and then installed the door. The thing is leaking like crazy.

I've caulked, stripped and recaulked the outside gap between the door and the plate about a dozen times to no significant affect. My latest tactic was to drill small holes in the track, stick the nozzle of the caulk tube in and fill up the passage under the track with sealant. Still leaks.

I also noticed a significant amount of water on the inside track (when the door is closed) when it rains heavily. Did I get a bad door? Did I do something utterly stupid? Aside from tearing out the door and starting over is there anything else I can do? (I'm thinking about caulking from the inside, but is that just going to allow water to get trapped under the door?)

This is driving me insane. Any help is appreciated.

There should be a weep system in the door frame so that water can't collect in the track. That weep system should direct the water to the outside.

Try this. When it's not raining, use a water hose and spray the GLASS -- let the water run off into the track -- DON'T spray the track itself.

If you get water inside the house, then the door was installed backwards from what the mfgr. intended it to be installed.
