climate control problem?? HELP

[redseal119]

so here we go 2005 f250 powerstroke with the digital climate control. the air works and gets cold but the other day it quit allowing me to change the selction of where it blows from. so it blows out on the top/defrost spot and wont go to feet or regular vent/face spot. the temp still works, the a/c works, the lights work, reserculation works, auto mode works, fan speed works, and the on off selection works it just wont blow out any vent but the defrost spot. when I do select another setting it does show on the screen that it is blowing out that spot but it is really just still blowing out the defrost spot?? Please help thanks

You have a vacuum leak, usually the 4wd hub seals go bad.

Hey guys I have the same problem with my 07 f250 2x4 how do I check for a vacuum leak? Will that fix the issue or could it be something else. Please help my wife and I are about to have our first child any day now and I need to get this fixed before he's born and we bring him home from the hospital thank everyone in advance!:confuse d:

Start with a visual check of the vacuum hoses. Look for any that are disconnected, or damaged. One of the common issues is the gray hose that either connects to a nipple on the HVAC box or in-line heater hose valve, it gets knocked off. In this picture, below my hand you will see what the gray hose looks like. It will either be on the box as shown in the pic, or be connected to the valve on the heater hose behind the oil fill tube.

If everything checks our visually, you can click on this link that was provided by another member and start trouble shooting the vacuum system. The hub seals tend to go bad and cause a vacuum leak.
