Air Conditioner

I can only get air to blow out the defroster so would anyone know what the problem might be and how to fix it? 2005 f250 6.0 4x4. I did a search and couldnt find anything on this.

Sounds like you lost the vacuum line that controls your airbox. It's a skinny plastic line on the passenger side under the hood. If you hear your vacuum pump running all the time then it's loose. There was a TSB on the earlier models for the same problem with air only blowing out the defrost, but I can't tell you where to find it.

The heads were replaced the other week so the line could have been loose and then fell off. It did work when the truck was picked up.

It's very easy to knock off. It's a little plastic tube like boost gauge tubing that has a rubber connector and plugs into a vacuum solenoid. The vacuum pump on my 04 sits in front of the blower motor on the top of the right fender well. You might check all those lines and see if one is off. I could be telling you totally wrong here as it might be an electrical problem, but this is the first thing I would look for.
