I had a chance to open up both panels. I had replaced both wire harnesses a few years ago and everything WAS working back then. Now the drivers side LOCK function is the only function that works. UNLOCK doesn't do anything.. Pass side does nothing. I was going to just order a new switch for Pass side BUT still kicking this to understand before doing so.
What's got me confused is that I swapped switches between Drivers side and Pass side. I would have expected is that the pass side LOCK would be the only thing working. What I got was the same.. Driver side LOCK only works. Everything else is nada. Why would it LOCK only on drivers side and NADA on Pass side. Thoughts?

Notice the wiring is different for the right and left side.
Look at the wires on the replacement harness http://www.ecklers.com/search.asp?ac...searchHistory=
Anyway all I know is if both switches are not good or one or the other is not good the power locks will not work. If you have the wires mixed up....same problem.

Look at the diagram up above. Sounds like you have a couple of wires crossing. What you are saying I think is when you swapped the switches the one on the passenger side is still locking the driver side?

If there are rivits you need to drill them out. You can replace the rivits with a nut and lock bolt when re-installing. Make sure they are the same size as the rivit. Make sure they are not long bolts...should be almost flush when you put the nut on.

Yep, drilled them out and will replace with stainless nut&bolts.

OK.. So I decided I needed to make sure the actuators worked before placing an order for parts. I removed both door panels and exposed the actuator wires and switches. Once you see the drivers side wires at the actuator it was pretty easy to test. I tapped into the hot feed on the drivers side switch. I then spliced into two of the 4 wires leading into the drivers side actuator. Apply juice to one wire and ground the other and both doors locked. Switch wires and did the same.. Both locks opened. So now I know I don't need actuators. I ordered one new switch and see where that leads me. I'm going to try doing some more testing to make sure Drivers switch wires are reaching Pass side wires while I wait for parts. Maybe a mouse got in there and bit through something..
Here are a couple pics of what I did. Hope it helps someone.

I wanted to jump onto this thread because I too am having issues with my 81 power door locks.
The locks were not working at all and I was also having issues with window regulators, so I've decided to rebuilt the doors completely…windows, motor, regulator, panels, arm rests…the works. I purchased 2 new lock switches, 2 lock motors and 2 new pigtails.
Installed all new lock components, pigtails, switches and motors. Connected the battery back up and immediately blew a fuse. So…yeah….there is a short….but where? I blew 2 fuses trying to find it. I did discover that with the switches not attached to the pigtails, no short happens. Help me track down the short or what's causing the short. Pigtail wires are butted to corresponding colors with the exception of the driver's side. Pink(original) to light blue (replacement) and Purple (original) to black (replacement)
Ideas?

Here is a post I made to a previous odor lock thread, hopefully it can help...
I agree with Gusto, if you are hearing the pop yet the door is not reliably locking/unlocking, clean and lubricate the latch mechanism, lock rod pivot and all rod connections. I also installed the actuators that Willcox sells as my originals had enough drag to make using the key difficult. The replacement actuators are made overseas but work well and have a much nicer rubber boot than the originals. I purchased some metric button head Allen's to fit the supplied nut plates.
I did not have to replace switches but during research found that there are different grades of switches, some absolute junk and some decent replacements. I have also read that some replacements don't have the word "LOCK" on the bezel.
Another common area for trouble is the switch pigtail.
You of course need to remove the door panels but all in all, working in the doors was quite rewarding when finished. Great opportunity to clean, lube and get the power windows working smoothly.
There was a helpful article that I found while searching Corvette Enthusiast magazine titled, Tired of Key Twisting. I don't have the link handy but if you don't find it let me know.
My car is a 79.

When I bought my 81 the door locks did not work at all. I pulled the door panels and found the PO had removed the actuators. I found the brackets on Ebay and bought new actuators. They worked great once then blew the fuse. The circuit has my radio and interior lights on it so its really annoying when it blows. I have replaced everything and it still pops the fuse only if I lock with the drivers side switch. I cannot find where it is shorting, its not in the door panel. So now I need to run a new hot wire in the circuit and abandon the current one in the harness.
