Power lock not working - Help alarm error code 46,47,3,60

[rswamy]

99 996 C4 50kmiles, bought a couple of months ago, power locks was not working. Good price so I thought shouldn't be a hard fix.

The problem;

If I use the key to lock, I can hear the gas door actuator cycle and a couple of clicks under the driver seat. No obvious sound from the door lock actuator. horn beeps couple of times and passenger door remains unlocked, driver door is locked. Same behavior when I use the key fob except, driver's door remains unlocked.

Removed both driver and passenger door lock assembly checked all microswitches based on the article on "renntech-Diy common fixes" Inner and outer door handle switches work fine. Only microswitches I haven't checked are trunk and decklid. I put the durametic tool on it and here are the screen shots

Drivers side secured closed

Passenger side secured closed

Drivers side locked blank

Passenger side locked blank

Drivers door blank

Passenger door closed

Front luggage compartment closed

Rear luggage/engine compartment blank.

what is confusing is that "Driver door secure" conflicts with "Driver door" don't know what to make of it. "Rear luggage/engine compartment" may be a problem too....

Well I did a little troubleshooting and finally found out that both the door lock actuator motors were frozen. I had to dismantle the two door lock assemblies and forced the motors to turn. Lubed it and works fine. Easy fix considering replacement of both door lock assemblies $400 with tax. Looks like the PO may have got some water in the door at some point and didn't drive it much, 6k miles in 4 years. Anybody need help with dis assembly of the lock mechanism, I can help.
