Will not open in the vent position either, it opens and closes but one side work first
You are all incorrect with diagnosis. And there is no button hokd calibration, stop it. Read on. So easy a caveman could do it. 1.5 hr job only removing glass.
(Inside vehicle)Remove the 4 hex screws that attach the glass to the rail guides and remove the glass panel. This will also allow for manual movement of rails. The glass is adjustable(hight only) so mind the position when removing the screws.
. Hold the glass like a pizza pan for it will slide down as u loosen each screw, remove the screws then lift upward and rest glass on roof. Removing the glass will give a good view of both guide rail and concting arms. The crunch you heard was one of the connecting arms plastic rail guide tips breaking. Picture a catamaran for a moment. The pontoons are the plastic pieces that slide fore and aft inside the rail and keep everything aligned. It will be the outside(pontoon) guide piece that failed. When that broke, a lot of play was allowed and began binding. Bless the poor folks who bought a whole new unit for nothing. I fabricated two pieces from the plugs off an older dell power supply. The plugs were the exact same length as the factory guides and even beveled ends. I only had to cut the plugs in half long ways and then install on the slider. Even the holes that are already in the plugs fit the stud (pivot stud that the pontoon slides onto) the guide. Sunroof will not vent if any of the pontoons are damaged. When venting, theses guides(pontoons) pivot upward through a slot on the top side of rail slot and rest on the rail so not to close by wind. Hope this helps. Any questions eamail me at dubyadubyadubya dot maxrevadvisors at g mail.
SOURCE: sunroof will not close
In my experience this is not an easy fix, the Sunroof rail is either broken or the sunroof has jumped the track because of a foreign object or misalignment. Either way unless you know how to take the sunroof apart I would take it to the shop.

It sounds like it just needs to be reinitialized. Turn your key to the on position with motor off and hold the up/full vent button down for at least 30 seconds or until your sunroof either clicks or goes to the full vent position. That should fix your problem.

The motor is in the front area of the roof unit.If you can drop the switch and trim around the front of sunroof unit and headliner ,you can can access the sunroof drive motor.The drive shaft of the motor can be turned mannually with an allen wrench which will assist in closing and identifying the problem area.If its hung very badly ...remove the sunroof motor then push the roof closed.

most of the time on those sun roofs when you hear the clicking noise coming from the headliner when trying to open or close your sunroof and you have to help it move that clicking is the gear in the motor skipping ,I just fixed one on an infinity the other day that was doing the same thing ,the plastic gear gets worn down and will not grab any longer ,hope this helps!
