this is in regards to this thread:
"Easy cheap quick fix for Ford defrost/vent problems"
but my questions seem to have been buried,
I am sure this is my problem, I share all the symptoms. But my vacuum hose is definitely not where this gentleman's is. I have looked everywhere that is visible off my manifold, have the bulkhead and air filter removed, and cannot find a hose that is even remotely similar.
I live in the Palm springs area(120 degrees) and really need to get this fixed. I would even settle for a temporary way to force the flow valve in the vent position until summer is over and I can spend more than 2 hours outside.
So any help in either area would be greatly appreciated:
Find the appropriate line
or
temporarily, manually hold in vent position

Did you get an answer to your question. I just did a temporary fix on mine. Underneath the drivers side dash is the accuator arm. I zip tied it to stay open until I can get this figured out. I have replaced vacuum lines, replaced the egr vacuum solenoid. Still not fixed but truck runs like new now. I did the zip tie thing today till I can get the "o" rings to change out on my electronic control unit and see if that is where it is at.
