[ALVIN]

Is there anyone out there that can help me with my problem. I have a 2002 325ci. My problem is that i cannot get my top to come down. If i open it manually and rise it all of the four inches that it will allow me, i then can press the close top buttom and it will indeed lock. But if i press the open buttom all i get is a clicking sound from the center of the back seat. I was told to check the fluid level for the top. My problem is that i don't know where it is located. Any other solution as to what might be my problem, and where is the fluid for the top?
