91 CRX Sunroof leaking = Musty car

[Si-R CRX]

I have a 91 CRX Si and my sunroof leaks. Water comes out around where the hatch struts bolt to the body. It also seems to make its way down to where my spare tire is also. It doesn't look like it is rust out anywhere so all the water should go to the drain tubes but I am wondering if the tubes are clogged or something. The tubes also have drain valves on them also so they may not be working properly. If anyone knows anything that would help it would be appreciated because I am tired of sitting in a musty a@@ car after it rains.
