That's your opinion. If the others want heat there based on their past experiences, then they're much better off having it there. I don't see what's so hassling about turning a vent off, the 240D owners do it all the time.

Yup, that's my opinion; they should do what they want. I also have a 240D with a manual center vent control, and I prefer the auto system in the 300D without the center vent blowing hot. If my center pod broke, I would have it fixed.

I did, because I wanted heat and/or ice cold air for the rear passengers that only the center vents provide easily. The center rear passenger will also have difficulty with this if the center vents do not blow warm air when we want it, because the side vents are blocked by the front passengers.

It's just a matter of personal taste, and if I remember you were also the same person who did not want the convex side mirror lenses, which you hated a lot. And if you want to be technical, you should still be able to also get heat through the center vents - only intermittently. That's what it says in the manual. Problem is it looks like it's a pretty common problem and I don't like it that way. I want the heat when I want it, and I don't want the Chrysler ACC to choose whether I get heat or not.

Let's not turn this into another debate, shall we?

No debate, I don't like convex mirrors and I do like the auto climate system as it was designed. I also like the manual system in the 240D, but I really prefer the auto system. If you don't like it, you should change it or put in a manual system.

You are correct that I occasionally get some heated air from the center vents, it appears only to happen when the cabin is close to the desired temperature and the air is just slightly heated. It's usually during the transition from heat to AC or AC to heat on a day like today (about 50F). It's not a problem, the air is more warm than hot.

I had center vent heat in my 300TD and loved it. 240D with manual slider gets it's air before the heater core so there is no way to get heat out of it.

I actually prefer that to center heat. My old saab 900 had a mode that sent fresh air to the center vent and heat everywhere else.

You guys are missing the point. When the center vent pod is broken, you have zero air flow to the center vent bad bad bad thing.

Now normally you want the center vent open when using A/C or outside fresh air. And to get the center vent to flow (when the pod is broken), you wedge it OPEN.

A wedged open vent works fine, EXCEPT when in the heating mode.

Therefore in the heating mode, you manually turn the vent flaps to CLOSED.

(or tear apart your dash and fix it)

I understand that problem, but some folks also wedge the vent open because they prefer to have heat from the center vent.

Yes but when wedging or not wedging the center vent which oil should we use dino of synthetic?















:D

If you want it open, open it, if not then don't. It's your car. Replacing the pod is some work but doable.

Yes, and which brand of filter should we stuff into the vents? Remember, round filters in W123 vents, rectangular for the 124s.

Simplest least intrusive and completely reversible way to wedge the center vents open is to screw a tiny, #6x3/4"? brass screw into the side of the plenum area from the glove box side.

-Remove the glove box
-Open and close the flap through the front of the vents with a long screwdriver to identify the oval head of the flap rod where comes through the side of the plenum.
-using just a screwdriver, screw the brass screw in immediately next to the oval rod end with the flap fully open. The head of the screw prevents the flap from closing and if you change your mind you can't even see the hole left behind from the removed screw.

So, if I remove the glove box I can access the plenum and block the flap open that allows air to come through the center duct? Where is the access into the plenum? Will it be self explanatory if i just pull the glovebox?

There is a rubber duct that connects the plenum to the two center vents. You will need to partially remove the rubber duct.

Thanks for this idea.

My center vents weren’t working, they did before. I suspect acc or the vacuum switchover valves, but don’t have time to dig in. The screw approach was the easiest way to do an unobtrusive, fully reversible (if the vac pod is working) mod. A tiny bit of rtv will seal that forever.

I always prefer air flowing past my upper body so I might keep this permanent anyway.
