(1998 528i) i have a problem with my sunroof to close. when i push the button foward it is suppose to shut...it doesn't, the sunroof thinks i'm pushing the button up so it opens the sunroof in the up position. i've switched the switch with my dad's 740il (1995) and it still has the same problem. do i need a new motor for the sunroof? cause it's working fine. is there a computer for the sunroof that i could reset or something?
