Still having problems

[Frustrated]

I'm still having problems with my central locking, the locks cycle when you lock/unlock them. I found problems with the trunk wiring harness, fixing them fixed the trunk lock motor, but the door locks are still a problem. The passenger door acuator has 5 wire going to it, Three for power and two for signal. With an meter should i see any readings accross the wire connector when I lock/unlock the car?

Thanks for the diagrams, they helped me greatly. I have since checked all of the wiring and continuity checks have eliminated any concerns of damaged wiring. And yet the problem continues.

Hi,

That one has a lock as well and it can cause the same problem as a door/trunk lock.

Can you elaborate on this a bit more?

Thanks!

The gas door lock accuator works but I don't think it sends a signal to the GM regarding if it is locked or unlocked. It only has two wires going to it, reversing polarity to lock/unlock. The driver/passenger door accuators have 5/6 wires, three for power and three for a status signal to the GM. I'm not sure if this is correct as nobody seems to know, this is just what I have figured out on my own. If you have any info I would appreciate your response.

I have reviewed the diagrams and it appears different than my car. Do you have any info on 1990 525i american spec models?

Man, that's a pretty cool reference link. Is there one for the 1989 E34?
