I'm having the same issue, my doors will lock with the fob, but will not unlock. I need to order the relays, however I am not looking forward to doing this, I never cared for taking door panels off and messing with electrical junk on cars, I would rather pull the motor!

There is only one actuator motor so we know the actuator is good so it must be an internal issue with the door module. The relay is the most likely cause and it is fairly easy to replace.
I have worked on dozens of door issues and I predict that the relay is your problem.
Let me know if I can help further.

I am a bit confused regarding which relay does what - the middle is supposed to be the unlock from what I have seen and read, but explain to me this...
My driver door would not lock with the fob. Unlock worked perfectly fine, so I replaced the "Lock" relay, reassembled everything and no luck, same issue. Then thinking maybe the actuator was the issue, I also replaced it - again, no luck. Now pulling ideas out of the air, I went ahead and replaced the unlock relay on the board.... wait for it...... Everything now worked.
Help me out here.... Thanks

My thought is that if the actuator was bad that the door wouldn't lock or unlock, but if it unlocks then the actuator is good. Not 100% sure on that, though.

Ok so I could use alittle help. I bought a 02 z06 couple weeks ago that was neglected. I'm loving the car but these little issues are killing me here. I used this great forum for tips to replace the passenger side window motor and regulator. After I finished that install I tested it and it worked, I was very happy. So while I had the door panel off I figured I would attempt to replace the door lock relays because the door lol didn't work on that side. So I tried it, didn't go so well, I had got a good splatter of solder all over trying to blow the holes clean. Thought I got that all cleaned up, then while cleaning one of the holes out I must have got it to hot and one of the rings that the pins go through came off. So I think I'm F'd here, right? Any way I put it all back together and now the window doesn't work, WTF? I can live without he door locks but I would sure like to use my new power window? Please help

Your best bet is to replace the door module as ther are somewhat cheap.
