UPDATE: I got a new actuator and its doing the same thing. I did confirm that 51217272999 is the part number for both left and right actuators. My local BMW offered to sell me the kit for $65.00.
I'm not sure what my problem is. If i connect the cable to the driver side actuator nothing works. When I hit the unlock button they all click, even the new actuator but they don't unlock. Nothing happens when I click the lock button. If I disconnect the cable from the new actuator the other 3 doors will lock and unlock.
If I don't find out something soon, I guess I will be taking her into the the shop. If anyone has any idea's please let me know.
