The driver's door lock actuator has stopped unlocking the car. I have been using the trunk lock which unlocks all of the doors fine.

I bought a replacement door lock actuator and it does not seem to be fixing thing.

I was wondering if the electrical portion of the door lock actuator is my problem. Can I test the three pins and what should the voltages be?

Or, is it a mechanical linkage problem between the door lock actuator and the door handle. Again, the trunk unlocks all of the doors, the drivers door does nothing.

Thanks.

Well, let me answer my own question. The problem was not the door actuator at all. (I now have a spare if anybody needs one)

The problem is that a little metal bit that connects the door key lock to the assembly with the remainder of the door lock broke.

I think that I can get you the complete piece as in your picture... However no key... Jim

I don't need the key. I'll take the part off of the other and use my tumbler.

How much and when can you ship? Send me a PM.

Thanks!
