Can not available right now but I'm more than willing to assist you. Just covering all bases, make sure fuse 67 and 9 is good in the under hood fuse block. If the sun roof switch and motor/actuator is good. Recalibrate the sun roof position by holding the sunroof switch to the vent position til it's open, release the switch and the hold the vent switch for 10 seconds and it will recalibrate. Any more questions please replay back. Thanks and please give a positive rating.
