Ford Excursion :: 2002 - A/C Blowing Air From Vents To Defrost?
My 02 V-10 Ex seems to be blowing Air from the front vents up to the Defrost unless it go through a series of events-- Hit Auto then forward Air then the fan has to be a 4 only. It will blow forward vents then go back and forth from theirr to the defrost. Also the Temp seems to be much hotter then it should.
Took a interstate trip this weekend though and it seems to blow much colder and do a little bit better staying in the front vents however still goes back and forth. Im in FL and its HOT!!!! The only thing I know is that its a vacuum system.. and that again its HOT in the truck as a daily driver.
Ford Excursion :: AC Not Blowing Out Of Defrost Or Floor Sometimes
The front a/c on my ex on the highest blower motor speed blows out the vents like its on low, but I can hear the motor blowing at full speed. It's not blowing out of defrost or floor unless I switch it. On lower settings I can barely feel any air at all. Only does this rarely. Could it be my vacuum pump?

Ok, I know I have a vaccum leak. I have manual hubs now and those lines are capped. The AC is blowing through the deforst and the pump is running non stop. I have replaced the vac pump a couple of years ago and it worked fine then. any other places to look?

my AC is only blowing through the defrost and the floor - It's a cool 101 degrees here today!!
We have changed out the battery, the actuator on the passenger AND driver side, as well as pulling the HVAC fuse from the fuse box under the rear seat - none of this has worked!

My 2005 Freestar (not the Freestyle) a/c is working properly except that it is only blowing through the defrost. I've read other posts about it being a leaking vacuum system on other ford vehicles that cause this problem.
1) I'd like to confirm that this Freestar a/c works on a vacuum system to open the a/c duct doors.
2) If it is, where are the vacuum hoses located? I'd like to check them to see if they are connected or if they have a hole.
Ford F-150 - 1997-2003 :: No Heat / No Air - Just Blowing On The Defrost And Panel
Every thing was working great then the AC quit. I ran through the air selector and all I can get is panel and defrost with no heat. I checked the vacuum line on the passenger side engine compartment and it looks good. Oh I also took the control apart and 3 of the five holes had vacuum to them.

Replaced the vacuum solenoid.. Thought that would fix the ac blowing threw the defrost when I switch to 4x4, but didn't fix the issue, 4x4 works great. There is another little diaphragm that has a vacuum line to it that opens and closes, could this be causing the air to go defrost? I'm going to go to a buddies house and test for leaks this Saturday, just trying to get a jump on it...

My A/C is blowing cold but only thru the defrost vents. First it was blowing normally from the dash but during acceleration or under load, the a/c would randomly blow from any vent, from the floor, dash, defrost. Now that stopped and it only blows from the defrost vents above the dash-board.

Ford F-150 (2004-2008) :: AC Blows Hot Air But Defrost Blowing Cold
My AC blows hot air, like heater hot, but the defrost on cold blows cold air. At first the AC would cut out at low rpm's (stop sign or red light) and cut back on, now its nothing. But the defrost blowing cold, enough to fog up the windshield, tells me its not the compressor or freon.

I have followed the vacuum lines but don't see any holes or cracked lines. I dont have the ESOF hubs so that is ruled out. Also checked the connector on the vacuum pump to make sure it still had power. Everybody says that when I turn the key to acc I should hear the vacuum pump running. I don't or do I feel it moving. Am I on the right track? I don't want to replace if not bad. Do all vacuum pumps run on keyed power? I honestly don't remember hearing it run before but that doesn't mean anything with my memory.

Ford Super Duty (1999-2016) :: 2000 - A/C Blowing Through Defrost Vent?
I have a 2000 f250 4x4 7.3 diesel. I had problems with my a/c and controls for sometime now. my a/c was blowing threw the defrost vent. I was told my blend door was bad. I bought a new blend door installed it,still doing the same thing. I was told to check my vacuum lines. I check them, they were bad. I replace my vacuum lines and my vac pump as well. that fixed my problem blowing threw the defrost vent. I can control my air flow from floor,dash vents and defrost vent. the problem I have, I not able to control my temperature when I turn my center from red to blue. It blows hot air and the air that is coming out of the vents isn't very strong at all.

I have a 2008 F350 and there is nothing blowing out of the vents or defrost for AC or heat. It doesn't matter what fan speed is set. Would this indicate a blower motor? Where exactly is it located and how to change?
View 8 RepliesFord F-150 - 1997-2003 :: 1998 - A/C Blowing Cold Via Floor Or Defrost Vents?
1998 F150 XLT 4.6l automatic,,,
Drove the truck on a trip the other day, about 650 miles with a loaded 5x8 trailer in tow. A/C started acting weird. When the truck was on level ground, or going down hill, the A/C was fine. Cold air coming out the correct dash vents. As soon as I started up hill, or put the truck under strain of acceleration, the A/C would stop blowing out the dash vents and would start coming out the floor or defrost vents, or just not come out anywhere.
When I turned the A/C off and just used the vent setting, it would do the same thing with the fresh air. I guessing this has something to do with my vacuum lines, somewhere. What I should be looking for and where?
Ford Super Duty (1999-2016) :: 2005 F250 - A/C Blowing Out Of Defrost
The A/C on my 05 F250 6.0 recently would not blow out through the vents. So, I replaced the vacuum pump and the reservoir tank. Once I replaced them the A/C still starts through the defrost vents but, after a minute or so starts to blow through the vents. I also noticed that the vacuum pump never stops running. Is this normal or is there something else I need to look for?
