Its a 2005 g35 couple...the sun roof opens fine, no problem with that but when its time to close her up the sun roof starts skipping....it attempts to close but then returns back, I have to sit their and keep on pressing the button until it finally desides to close....and when it finally desides it wants to close it goes frontward, stops, closes more...stops...closes more, stops...until its all shut....dunno what it is....

Any help? Thanks!
