Parasitic draw from window circuit on '87

I've noticed parasitic draw on my '87 for some time, but seeing as I don't drive the car much, I always kept it on a trickle charger. Recently, I have been sorting some loose ends and wanted to get this one tackled before I possibly list it.

When I started searching for the issue, I found some problems with the door switched and not shutting the circuit off after I opened the door, so I replaced them and that solved that. However, I still see a draw on the window fuse when I test it with my multimeter. From what I understand, the '87 does not have a window ECM and the problem is likely somewhere else. From what I see, the windows and roof operate as normal and stop working with the ignition off and the door cycled open. Also, it looks like the relay is the original to the car.

Thoughts?
