2002 4x4 question
Hi, Don't post on here very often but come here for excellent advise so thanks in advance.
Just recently purchased my 4th powerstroke. an 02 7.3 c/c 4x4 with 4inch lift.
My question is when you put the truck in 4x4 with the ac on the air changes from blowing out of the dash vents to blowing out of the defroster vents. After you switch back out of 4x4 it takes a few minutes and the the air redirects back to the dash vents. Is this a common occurence or is there a problem somewhere?
I also had a 2000 7.3 c/c 4x4 that did this also. I have checked vaccuum hoses but am at a loss as to why this occurs.
Does anyone have any ideas or suggestions.
I am not new to the ford diesel, have had a 93 7.3, a 2000 7.3 and a 05 6.0 and now this 02 7.3.
I went back to the 7.3 as I beleive it is the better motor, the 6.o was great except for the injector problems, had all mine replaced under warranty but decided to bail before the warranty expired.
thanks
Rick

There are some threads in this forum that talk about the testing procedure and how to narrow your search. If you run some searches you can probably find what you need. I have a few threads saved in my favorites on my home computer (at work now) and I know that a couple of them relate to this problem. When I get home I will get you some links.

Thanks Scott, that would be much appreciated. I am by no means a mechanic but am fairly handy with tools, and do all my own maintenence,
I am waiting on my cold air intake, 4" exhaust and SCT to come in this week, so I will be busy adding on to the truck.

No problem at all, Rick.
Here are a couple of links that talk about your problem. The third link is to a new set of vacuum hoses should that end up being your problem.

I must say I am very proud of all of you, 4 people in the same thread actually spelled VACUUM right. You all get gold stars for today. Now sit back and watch how many people don't know how to spell it.
And yes, RPS58, you do have a vacuum leak.

Thanks for all the replies and help,
Upon further inspection of the vacuum hoses I found where someone had used a zip tie to secure the lines and had crimped the the hose I guess enough to cause a significant obstruction, I removed the tie and the sysyem is working as it should, no transfer of air to the defrost vent.
Again guys
THANKS

Yes Sir, thats why I come here, cause I love the diesels and great help is hard to come by, wish I could contribute more to fixes but hey I train Horses so if you need horse help give me a call.
On another note THE AFE intake I orded is on back order for who knows how long, called a local truck supply and he said go with K&N its the best out there
Told him "NOT", so I am off to the NAPA parts house at lunch to pick up the 6637 til the afe gets here.
So any way Seriously Thanks for all the help and I am a Certifeied Gaited Horse Trainer, so if any one needs help shoot me a message.

I rode a horse for the first time in my life about a month ago. Took the kids and wife on a Texas trail ride at the state park in Huntsville. Amazingly strong animals. The one that I rode was a like a 4x4 horse. He had to be to carry me.
