e39 sun roof won't tilt up.

[prusse]

I'm looking for directions on how to disassemble the sun roof to figure out which part is broken. It slides open and closed but will not tilt up. (It will tilt by pushing up on it from inside but won't stay open; it just falls back in place).

you need to replace a small plastic inside the rail assy...it's a common problem of bmw...just go to bmw parts tell them that tilt sunroof won't work and they know already..
