Everytime i open my sunroof all the way back and then try to close it, it comes almost all the way closed and then opens up again. I have to try and close it 3 times and hold the button in at the same time to get it to close.Once i get it to stop goin back by itself it still leaves a gap and i have to keep tappping the button until i get it to close the rest of the way. Not sure what the problem is any help would be nice.
