Kitchen slider window leak

I'm trying to find the source of a newly discovered leak. Water is running from under the window trim, down the wall and onto the kitchen counter. The rain stopped a bit yesterday, and so did the water accumulation. During this time, I was able to reproduce the effect with a hose. I directed the nozzle toward the lower part of the window from above with a gentle spray. I believe water is accumulating in the slider channel, and somehow entering from there. The drains are clear, and I've observed water running out where it should. Any one have any idea what the problem might be? Isn't the channel solid except for the drains?

And if I decide to get help on this, who's the best call? RV repair shop or glass company?

Thanks.

    I worked my plan a few minutes ago. I poured green water slowly into the track until it exited the drain holes. No water leaked in, until I closed the window. Then green water began accumulating on the counter. The way I see it, this means the frame is cracked or defective. Am I missing something, or do I need a new window? Thanks.

    Jerry,

    Yes I thought of the roof penetrations above, but unless there are multiple leaks, the hose test ruled them out. In a similar way, the hose test ruled out leaking behind the window flange. The year old window tape still looks good anyway. The only mobile tech in the area has not returned my call.
    I just picked up some food coloring. Colored water running down the wall after being poured into the channel will prove my hypothesis even if it continues to rain. Should know more this afternoon.

    It sounds like you are certain that the problem is isolated to just the window. If the drains are working, but water accumulating in the channel, faster than going out the drains, you need to figure out why. Does the window not fit properly? If no obvious reason, I'd start by removing entire window/frame, and reseal behind frame, reinstall window/frame. Removing the window, may require a helper, but not a hard job.

    Never overlook a possible point of entry above the window.

    A mobile RV tech would be a good option, if you don't want to tackle this yourself.
