Vent problem - F-Series & SuperDuty Diesel Forums

alrhoads · 01-05-2012, 02:58 PM

For starters I want to say hi. This is my first post on here.
I am working on a 06 E450 diesel and the vents have stopped working. I have checked the vacume pump and it works, I have vacume to where it goes down the fire wall and I lose it there.
I can not see where it goes, but I see where it comes through the fire wall on the pas side at floor level and I have no vacume there. I am not sure what to do at this point other than remove the heater core and box to get to it, do any of you know of a better idea?

I am guessing that you have ESOF (Electronic Shift On the Fly). Better check the vacuum lines going the the hubs. That is usually where they leak.

airhoads.

Sorry for the confusion, this is not my truck. The ambulance at the fire station has the problem, and they always ask me fix things.
It is a E450 van and is 2wd.

I can see that the vacume line goes down the wheel well twards the fire wall, but I cant see if it goes anywhere els before it goes through the fire wall. The leak would have to be where i cant see it, I just dont know what all is down there if anything.
