Hi Tom and Dr Bob,

I solved my problems with my dashboard. I'll explain what I did. First I cleaned all 3 connectors on the back of the dashboard with contact-cleaner. No result. I dissasembled the speedometer again and found that the 4 pin- connector on the back maybe didn't make contact. I bended the plates (don't know how to call it otherwise) a little bit and assembled again. Made a testrun and both speedometer and odometer worked.
Second problem: the lighting of the dashboard. First found out that the lights need 12V (because I wasn't sure), then found which pins of the connector are the ground and the 12V by looking at the tracks on the printed circuit board. I put 12V on them and the lights worked. Measured how much voltage I had on the female connector: 12V. Then found out that the contacts on the female side where not touching the male connector. I had to bend all iron strips very carefully to the inside with a very small screwdriver. After that the dashboard-light was working.
The voltage-meter on the dashboard is still showing 16V. That will be the one of the next things I will try to solve.

Hi guys,

Here are some photo's of the plate that is on the backside of the central ventilation opening in the dashboard. This one is damaged and cannot open or close the ventilation opening. I want to repair it with 3D-printed pieces. Can somebody share some pictures of the same plate but in good working condition? Hopefully I can find out that way how it works and what to print exactly.
Thanks in advance and greetings,

Bert

I can't tell where/what flap that is? Where is it behind the dash? I just so happen to have a spare heater-core unit on my bench (along with a dashboard) and don't see a flap that looks like that? Did you have to take the heater core plastic housing apart to find this inside? Or am I not looking in the right places. The only flaps I can see without taking it apart are shown with the arrows below and neither looks like the one in your picture? Did the 968 change parts behind the dash by any chance?

Yes. Sorry I should have figured that out! I will take some picture for you this afternoon. Not sure where you live, but those center vent inserts are easy to find in the US. But I certainly understand the desire to 3D print parts. 8-) :thumbup: :wave:

Hi Tom, I live in Belgium. I didn't know they were easy to find in the US. That makes me think that if they are easy to find there, then they also should be easy to find in Europe? Or am I wrong?

Belgium?!? For sure you should be able to find one! I spent time in Waterloo for work back in my younger days. Beautiful place in the heart of Porsche country! Look for the whole vent insert thing, like this one:

I'll still take some pictures later -- looks like the corner pivot post snapped off yours...
