W123 Center Vent Problem
Just noticed that my center vent flap is not opening when it should. Any hints on the best way to jury rig it to the open position?

The actuator that opens and closes that vent is behind the vents. Pull the glovebox and you'll be able see it. You can remove and plug the vac line, then manually move the actuator to the open position.

Okay. I am guessing that I will need to do something to hold the actuator to the open position. Isn't it spring-loaded to the closed position?

Yes I think you are correct. You might be able to remove the spring or wedge something in there that won't allow it to go back.
If the actuator is still holding vac you might be able to pull vac on it then plug it really quick, so it stays put.

I just bent a piece of flat thin aluminum stock and put it down the vent and hooked it over the edge where the rubber boot fits.

I'm having a similar problem and I want to try and fix it this weekend. How does one manually move the actuator? I've never seen what it looks like and I wouldn't know where to begin.

If you can chase the vac line down and put vac on it with a Mighty Vac to see if it will hold vac first. It might not be the pod, it might be a line or the elec/vac rail just above the back of the radio thats leaking vac. That pod is hard to work on one handed.

On my '84 the pin that held the actuator linkage to the center flap had broken. Once disconnected from the actuator the flap opens and closes freely ( ie no springs, etc).

So I took a look today and it looks like that center flap actuator will need to be replaced. We tested vacuum pressure on all the lines and it's all solid, but the actuator still does nothing.
Now for the interesting part... I couldn't help but notice how difficult it was to get to the lines on the back of the actuator. That being said, I feel as though removal and replacement of the actuator itself will be a terrible chore. I'm hoping there's some trick of the trade that I'm missing here, because the only other conceivable way to get that actuator out appears to be removing the dash, and I definitely don't want to do that. Any suggestions/insight would be greatly appreciated.

One handed maintenance is frustrating. One option is to disconnect the pod from the lever and move the lever manually to the open position. You may have to wire it open.

Further investigation reveals that my actuator works fine; it's just is not attached to the flap.
