Sliding Window Leaking when it Rains

The passenger sliding window on my 2006 Hurricane 31D leaks water when it rains The water is running down the out side of the glass into the track from the top and filling up the track at the bottom and then goes down the inside wall to the carpet. It appears that the rubber has pulled away and that a portion of the felt (for lack of a better word) inside the track is worn or missing. any Idea how I can fix this? Where can I get parts for the inside track. Hope I've explained this correctly.

Problem solved. I removed the tracks top and bottom and the one for the screen also. I cleaned them and put a little Silicone rubber lube on them and then reinstalled. There is a rubber insert that holds the top glass in and one corner had shrunk creating a gap at the top and acting like a funnel when it rained allowing the water to run down the vertical track to the bottom track filling it with water and the water could not get out the partly plugged weep holes fast enough. I pulled the rubber insert that holds the glass in out part way so that the gap would be at the bottom and not at the top. I took a garden hose and put a lot of water on the top of the window, and with the weep holes clear I could see water running out but not filling and over flowing the track. Problem solved for now.
