Are the power lock actuators for all E34's the same? I recently replaced the rear doors on my 1992 E34 ( because of rust ) with doors from a 1990 E34. The actuator from the '92 doors worked for the right rear door but not for the left rear door. Does anyone know if the 1990 doors used a different actuator than the 1992 doors? Please email your advice to Nachtwey@aol.com. TYVM.
