Passenger door lock only works manually

[autojack]

Here it is, my official intro post with question! After a couple of years spent learning and refining my interest, I conducted a serious search over the last few months and ended up with an amazing 1988 coupe. This is my first Porsche, first German car, and first rear-engine/RWD car. I've been a nuts and bolts DIY car guy for 15+ years, so this is just the next phase. I'm looking forward to learning a lot and this forum has been an amazing resource so far.

To my question: the passenger door lock only works manually. The central door lock button and key from the outside won't lock/unlock it. I'm guessing either the push rod from the solenoid has come off, or the solenoid itself is bad. Anyone have any other thoughts on possible causes or things I can do to diagnose? I expect I will need to take the door cards off - info or pictures on that procedure would be appreciated.

Not sure why, but photo uploads don't seem to be working. I'll try tomorrow for the obligatory picture of the car

The central locking function won´t work correctly if you have a defective microswitch on the back of the lock. Had a similar problem myself

Usually it's the rod popped off the upper latch. You can see it with a flashlight with the glass down.

Sir - your car is beautiful! Congratulations and good luck. I am afraid that folks may miss this because of the topic line - maybe start a new one just for this(?).
What color is that?
