94 E320 Center Vent problem
 

Hello Guys,
I'm not getting air out of my center vent on my 94 E320. Anyone know what can cause this? The flap seems to be opening with the flow wheel. I suspect a vacume pod to be suspect, but can't find where they are located. Any help will be greatly appreciated. Thanks. Bob

We just had the same problem on my son's 93 #00E. In our case, it turned out to be an easier (and cheaper) fix than pulling the dash for a bad element. If I recall how our tech explained things, after he checked vacuum response at the 3 way vac valve behind the glove box area air bag, he determined the problem was probably elsewhere: under the battery tray in our car is a vac hose which goes from the vac reservoir in the passenger fender to the firewall. This hose had cracked and needed replacement. This was a lot less expensive than if it had been a pod/actuater/whatever under the dash. I have not seen these parts and am not conversent with the exact names or location, but this inexpensive hose fixed the problem.

There are a ton of threads on the center vent problem in the archives, so try a search on these to see what others found with this problem. Good luck, and hope this helps.
