Sunroof stuck closed

A couple days ago, sunroof made a crunch when I closed it. Figured it was something stuck in the track since I was parked under a tree and it was stormy. Opened and closed fine one time after that and now the rear passenger corner of the sunroof will not lift up. Anyone faced this and found a solution for getting the corner un-stuck?

One corner getting out of sync is a common issue... One motor drives both sides of the sunroof. Light grease evaporates, spring-coil becomes uneven.

Use the manual wrench drive to rewind roof shut.

One, I have no idea if there is a manual wrench in the car :rofl: and two, hopefully that won't result in it just getting stuck again or stuck open ha.


Edit: It's just an allen key under the SOS/Interior light panel?

yes, right there. However, this does not really fix anything towards root cause.

It's not simple to troubleshoot because gearing is all hidden.

-- Roof needs good lubrication to keep mechanism mooving smoothly,
else:
-- Plastic pins on the glass slider may get broken once forces are exceeded.

I just opened up that panel and there’s no Allen key hole. It’s just a round hole in the motor

is this cap not a plug.... ?
I'd be surprised if this did not have a manual drive for rainy-day operation.

There’s a hole in there but it’s just a hole. No spot for an Allen key to go

Plan B: use your scanner
The OCP Module let you skip-skip-skip manually when roof is de-normalized and button unresponsive.
