I have a 2018 Equinox Premier and today I ended a call by pressing the button on the steering wheel when all of a sudden the frigging Sunroof opens up! WTF? Then, neither it nor the sunshade would close properly. I finally got the roof to close but the shade closes about halfway then stops. Checked the fuse box in cargo area and noticed it was wet in both corners behind the taillights. What is this?

 

sounds like you have a water leak. clear your sunroof drains
