Hi… both rear drain tubes were clogged and yes. No more water issues. Hopefully your control module will be a plug and play but I did have to have mine reprogrammed at the dealership which cost about $450. The best way to clear those drain tubes is to pull back the rear bump cover on each side by taking the screws out behind the rear wheels, park on an incline, pour a little water on each side of the sun roof and you may need to jack the car up slightly on each side. Then place a shop vac on the drain tube exit holes and it will clear them right out. Much easier than dropping the headliner. Take care and good luck!
Hi… this is maintenance issue, not a GM issue. This happens to all sunroofs regardless of manufacturer. The main issue is most of us don’t find out about this until it’s to late. If you follow the maintenance recommendation I provided in a follow up video I posted, which applies to all sunroofs you should be trouble free going forward. Thanks for your comment and take care!
Having the same issue. Is that the only place that was clogged ? Also did you resolve the issue

GM should’ve been sued into oblivion for this 🤔💯
