2009 EB Moonroof issues (and temporary fix)

[Cade _ATL]

My moonroof likes to go into the vent mode. Problem is, if I shut it, it pops right back into vent on its own.

I'm thinking it may be a fault in the motor - limit switch or the like.

Any thoughts or solutions?

Given that it's going to rain tomorrow, I wanted to get it shut and keep it shut.
Here's what I did, I noticed that if I pushed and held the 'vent close button' at would stay until I released it.
So, I did just that, then I turned the key off while still holding the vent close button.
With the Expo still off, I popped down the overhead console and separated the moonroof wiring connector, and left it unplugged. Then remounted the console.

Sadly, the moonroof shares fuses with other things in the truck, so that wasn't an option. At least I have it decidedly closed until I have more time to sort it out.

FYI, I found the way to manually operate the moonroof -
You need to drop the overhead console, and there is a allen wrench slot in the center of the drive mechanism, turn it counter clockwise to close
I haven't tried yet, but perhaps you would turn it clockwise to close from vented - I'll post an update after I try it.
