I have an old Gen1 that I'm trying to fix up for my son. It's basically the exact same as my vehicle ('90 LWB 3.0/V6). The moon roof is stuck closed. The motor turns and tries its darndest but the roof doesn't move. I think that it's frozen maybe because the seal is pretty destroyed and there's a bunch of rust around the edges.

Is there any way to manually crank open the roof on these vehicles? I read some bits and pieces here about using a hex key to do this but I can't find one in the vehicle nor do I have any idea where I would put it to crank the roof open. The FSM seems to be completely silent on this subject, so maybe it's not for these Gen1 vehicles.

Anyway I may end up replacing it but wanted to see if I could get it opened first just try cleaning it up and opening the drains.

thanks,
steve
