2006 C4S Cabriolet: Unable to lock, Window Stays Dropped

[turtleturtle]

I recently purchased a 2006 C4S Cabriolet m/t US Model and since my ownership I have been unable to lock the car via the remote and the driver side window does not automatically fully close.  I replaced the latch assembly hoping it would knock out one or both problems but nothing has been resolved.  Fuses look ok to me. Below is further detail and Durametric codes -- is there anything in there that points to likely culprit(s)?

 

Appreciate your help!

 

Door will not lock with remote (double beep) or with key.

• I am able to use emergency procedure to lock door (turn key three times)
• The doors will lock if I hit the locking button inside car.
• The remote unlocks the car fine.

FIXED: Driver Side Door Control Unit/Motor Driver side window drops the 10mm or so when opening door but does not go back up upon closing door.

• If I am in the car I can manually roll up the last 10mm and it will stay up until I touch the handle again. If the door is open and I roll up all the way it drops the 10mm instantly.
• Passenger side works as expected.

FIXED: Driver Side Door Control Unit/Motor: Interior lights stay on.

 

Potentially unrelated issues/info but will mention just in case

• FIXED: Rear Control Unit was set to Boxster, updated to 997 cabConvertible top when closing will cycle through latching and never stops, but does latch but I have to let go of button.
• Rear right window at times does not close on first try
• FIXED: Rear Control Unit was set to Boxster, updated to 997 cabSpoiler button does not do anything but spoiler can be activated w/ Durametric
• AWS module can not be found (I disabled in other modules)
• Aftermarket radio is installed

On my 07S Cab, I had only one of the problems you listed- driver window drops about an inch but doesn’t come back up when door is closed. I had my dealer fix it. They replaced the control unit at considerable cost. They had to take the door panel off  to replace it.

Thanks CarreraLicious 👍-- I replaced my driver's side door control unit/motor with a salvage unit and that fixed the window problem.  It requires taking door panel off and then it is just two plugs and three screws to replace.  Easy to do other than the headache of dealing with the plastic clips in the door.

Good to hear you got it done yourself! Nice job!

Any resolution to your issue with the car not locking? I'm having a similar issue after having a new key made. The mechanic did successfully get a new key made, but neither the original key or new key will lock the car any longer.
