I have a moonroof question. I have a 1998 BMW 528i with 140K

Resolved Question:

I have a moonroof question. I have a 1998 BMW 528i with 140K miles. The moon roof slider and up and down functions work perfect. The only problem is with the slider part. The glass slides back fully but when you go to slide it forwards to a closed position, it gets within 3-4" and gets hung up on the "black bar" that is spring loaded and runs across the front part. This "black bar" is actuated when the glass starts approaching on closing it starts to lower to give clearance for glass to pass above it and become fully closed. The problem is that this "black bar" is lowering but needs about less than 1/2 " more lowering to allow the glass to pass above and complete the full closing. My question then is: Is there and adjustment for this "black bar" and if so where is it and how to do it correctly. Please provide pictures and detail with answer please. By the way, if I slightly apply a little downward movement to the black bar just before the moon roof window approaches, then the window passes this obstruction and continues and closes properly with no retraction. Also, I have reset the mechanism by holding the button for 15-20 seconds while the window is in the up position....this did not help this obstruction issue I am facing now with moonroof..........

The picture I have provided you shows all the arms and plastic feet that are used to press down the sunroof wind deflector (which is the black bar in the front of the sunroof which goes up and down) You will need to remove the sunroof lid by putting it in the tilt position, removing the rubber gators and then remove the torx screws on each side of the sunroof lid. Once the lid is removed you will be able to inspect these arms to see why it is not lowering the sunroof wind deflector. You are going to be looking at and inspecting the items in the photos # XXXXX With the sunroof lid removed you will still be able to activate the sunroof into the close position so you will be able to see what the problem is.
