new to the forum, questions about climate in 124

Hi all, I'm new here but have wrenched a lot on cars. I'm fairly new to the 124 diesel though. I changed front seal, turbo, and injection pump seals. that wasn't all that hard. now I'm wanting to get the center vent to open. it won't open even when full vacuum goes to it. I thought about drilling out the 2 rivets holding the pod so it falls down and I can push the vent open manually. you know, get the actual vent out and push it down..
is that the way to do it? I don't want to pull the dash rightnow.
thanks for all your thoughts!

So when I replace that pod it will work again? if i put vacuum to it it doesn't operate the flap...

Yes

The pneumatic control system of the mechanical "Pods" consists of electro-
pneumatic valves actuated by the pushbutton CCU regulating the Vacuum
produced by the mechanical pump on the front of the engine.IF the hard
plastic lines have no cracks or splits AND the rubber "Connectors" are not
cracked or split...the only nonfunctional unit is the rubber diaphragms in the
pods.(the hardest working and most stressed part of the system)
The "Test Bar" is behind and to the left of the glove box liner.(You can plug in
your Mity-Vac to any of the pod circuits and test operation there)

Usually, if you've got a lever movement problem it's a pod.

And if you're gonna go in there (take the dash cap off) it's best to replace all
the pods (one's bad...from age and use...others to follow soon)[because it's
such fun to have to go in there 3 or 4 times]

I looked at a car at the junkyard and I couldn't quite see how to take it off. do you have to drill out the rivets and then rivet the new one back? who sells these units anyway? taking off that top part of the heater box seems a bit of a ***** too, as there are some bolts pretty much right underneath the bottom of the windshield... how on earth do you get to them?

The pod has to be removed from the metal bracket. There are three plastic pins/protrusions on the pod, three push-clips on the pins, you will usually destroy the pod trying to remove it.

so, really, why not drill the rivets and have it open all the time? you can still close it manually at the vent anyway. that's what I do to 123's when that pod breaks. you don't have to drill in them though. I mean, when you can improve a car by getting rid of design flaws, why not hey.

I understand it's not the way to go yet it works flawless!! drill the rivets and push down the flap! then controls are manual. I even made a nice lever in the glove compartment that controls the defrost! (that pod was gone too) superb I say, 30 minutes of work and it's never going to break again.

Good thinking, otherwise you might need to replace it again in 21years.

Vote YES on Center Vent Heat!

I fixed the broken center vent pod on my 123 by pulling the lever and wedging the flap open. Left the pod alone except for plugging the vacuum line so it wouldn't cause a leak.

It's nice to be able to have center vent heat. So nice that I may do the same thing to the 124.
