Only now that winter is releasing its wet and icy grip on us in the Pacific NW, I have opened the sunroof today (in the sun actually) and ran some stiff, insulated wire down the front holes. To be more precise, I ran the wire down the left side seemingly without problem. But on the right side, the wire only seems to go as far as maybe 2/3 way down the pillar and then it hits something that blocks progress entirely. I have not tried to put any water down there yet. But I am wondering if the left and right sides have similar routing and what I might be hitting on the right side. Thanks!

PS on the left side, I can run a longer length of this wire up from the door jamb but cannot seem to make it come out the top. Neither can I make it come out the door jamb when feeding through the top. Maybe there is some form of connector or something preventing this?

On the right side, i can run the wire down only about half way to the jamb and only about half way up from the jamb. In both cases I hit something quite solid and resistant to the wire. No idea what. Again, maybe a connector or splice? I removed the right pillar trim hoping I might be able to see what is going on. But there is just painted metal there, no tube I can see.

I guess I should try to pour some water down there to see what happens... Well the fronts drains seem to work fine. No idea where the rear ones come out but once I figure that out, perhaps the water test will tell me more. Thanks!
