1994 C280 109k miles (with new water pump, belt, and thermostat).

Sunroof will pop up and down, but will not pull back.

I don't believe the C280 manuals are out yet. Does anyone know if this is similar to a 1993 300e or a 1994 E320?

Shop time on this would kill me, especialy if it was just to replace a $20 part.

Thanks.
