Central Locking Issue

[maytag]

update:
after ********************!ng with it some more, it seems I can lock the doors and arm the alarm by inserting the key in the drivers door lock and turning clockwise, twice. When I do that, the alarm light on the dash, and the central-locking button LED flash together, fast, for about 10 seconds, then a slow flash. Pressing the unlock button on the fob works to unlock and disarm, but then will not lock / arm again.

78F350, dood, did you have this issue with yours when you replaced with the VW door-lock actuator? 'cuz this i how I'm leaning at the moment.

grrr....

I've got some good news and some bad news. I'm pretty sure that your VW door latch is the problem. It turns out that they are electronically different from the Porsche part. I didn't realize that until the fix I posted had been used by millions of people spread across five continents (no known cases in Africa or Antarctica). ...I feel bad.
It can be fixed, by using the original Porsche latch electronics with the mechanical portion of the VW latch.

Here's the follow-up post:

I have a 'new' car to fix now, so I will be doing this repair again soon. I'll detail it further when I get to it, but here's the basics:
The latches that I have seen failed were worn out where the microswitch contacts the mechanical door latch - The switch was still good, but the latch didn't push it enough.
I'm going to take the mechanical portion of a new, cheap VW latch and swap it onto the old Porsche part.
Just two screws and a little gentle prying.




Generally, all the moving parts of the cheap ones can be swapped over to the old ones as needed. On the particular one I have on my desk, the mounting holes for the microswitch are spaced slightly different, but can be 'adjusted' or forced. I'll probably just solder the new switch on.

Oh dood..... you're such a stud, man. You just saved me (I hope) many hours of stress and worry. Thank you.

I'll admit that every time in my life that I've come across one of these types of ideas on my own, and everybody wants me to do it for them .... I'm reticent. Always. Because this kind of thing happens, and SOMEBODY, eventually, will get mad about it. Haha.
Not me. I know the risks. And I appreciate guys who innovate, like you.

So thank you. Twice. (Once for the idea, and once for the notice about it ;-) )

I found your video on YouTube. You've probably added a note there..... but I really didn't watch the whole thing; I scanned until you listed the part number and then I went all maverick. If you're really worried about it you might edit the video with a caption or something. (Which I probably would've ignored anyway)

I can attest to this fix. I bought a set of replacement VW door locks with 9 pins that fit perfectly but did not lock/unlock with switch or remote. I swapped the mechanical new parts onto the electronic from the original and WOW - I have locking doors for the first time since I've owned the car. I did have to switch out the spring loaded slide mechanism that mechanically locks/unlocks because the cheap VW part had a plastic part where the original was metal (see photo) -- used the metal piece from the old and it works great
