W123 Vents

Can anyone point me in the direction of how to remove/replace/install the front air vents from the dash? I have two problems. One is that I dislocated the driver side door vent while reaching trying to push out the Instrument Panel... didn't realize the sound proofing fabric was all attached. Two, eventually I am going to try the method of fixing the center vent vacuum pod and I have read a description on how to do it accessing it through the center vents, but the process describing removing them is a little unclear... moving the stars 45 degrees then removing the wavy washer.... A diagram or pics of how these items are installed in the dash might really help.

Thanks
Doug

The plastic ring with the chrome trim comes out from the front, the actual vent comes out from the rear. Once you remove the hose from the back, you just kinda gotta push in, towards the rear of the car with one hand, and hold the ring steady by pushing towards the engine, and twist at the same time. Be careful not to break the tabs, etc.

Center vents are easily reached with the glovebox out. Not sure about the driver side vent as I've never replaced one on that side. I'd think removing the cluster would be the way to go...

As per your advice, I broke the tabs, repeatedly. Oh well. One issue with the driver side is that the vent itself is kind of stuck in some sound dampening material so working back there is tough. There are 4 receptacles on the vent itself and 4 tabs on the outer ring. I managed to break 7 out of 8!! (I stopped just short of perfection.)

A quick solution. On the vent itself there is a channel where the outer chrome ring sits into. This is normally where the chrome outer ring's tabs would then latch onto the vents receptacles. On the outer side of the channel, I applied a piece of electrical tape all the way around on the inside of this channel and folder it over the edge. It required me to cut the tape every 2 inches or so to keep its rounded shape in tact, but the idea was to basically make the channel a fraction of an inch smaller by adding the electrical tape. I then removed that wavy retainer nut and put it aside and gently forced the vent from the inside and the outer ring from the outside together. Holds pretty good and the vent doesn't move under normal use. One strong accidental push might be a problem or heat over time, but its a fix.
