how do i adjust the sunroof??

when mine is closed it appears that toward the front of the Maxima it is a little bit higher the nthe roof line(about 3mm) and toward the back of the max it is lower then the roof line (by about 3mm), i know it doesnt seem like a big deal but it is big enough for some air to be heard through the roof when it is closed,

i dont want to take it in to the stealership for this minor issue, is there a procedure to adjust the sunroof somehow??

 

mine closes a little too tight, so it pulls the roof forward just a hair and I can actually see light through the gap.

I asked at the dealer and he said "there are no adjustments. It's all one piece and I'd have to replace the whole thing."

Of course I said "then do it"... waiting for it to come in.
