X5 rear trunk lock/unlock not working

Has anybody had a problem with the rear trunk motor stop working? (The upper lock, not the lower one) It is a problem because when the vehicle is unlocked you would press a rubber pad (above license plate) to pop the trunk, but now that the rear is not unlocking I can not pop the trunk. Only with the button inside or the remote will the trunk pop. I would prefer everything to work as factory as possible. Oh, before the motor stopped working when I turned on my lights (parking lights) my trunk would pop. Happened when I was driving then after that the rear trunk stopped locking, unlocking, and popping (with the button the trunk).

Never mind, the actuator is dead. But I have a new problem, when i arm the x5 the parking lights don't flash and the horn does not beep. It flashes and beeps when i disarm. Any suggestions on how to fix it?
