Ford Excursion :: 2003 V10 - Blows Out Defrost Only

Mile marker hubs on my rig. V10. Plugged 2 ports on what I thought was the vacuum pump pass side middle of the fender. The lines coming out of what I thought was the vacuum pump were molded together going into two separate ports. I plugged both ports. What did I do wrong and what should I plug?

Ford Excursion :: AC Climate Control System / Air Only Blows Out Of The Defrost Vents

So in the past week only on certain days I have lost my ability to change zones for where my nice refreshing cold air blows on me from. It only blows out of the defrost vents. I here a fluttering noise under the dash when this happens. Also under the hood where all the AC hoses and such are located I feel cold air coming from inside the black box just next to what looks like the blower fan assembly. I don't believe I should be feeling that.

Ford - Explorer :: 2004 - Air Only Blows Out Of The Defrost Vent

I've got a couple different problems. The first one is that no matter what setting I have it on, air only blows out of the defrost vent.. Why this is happening? or is there already a thread about this? i saw a thread for this same problem, but it was for 2nd gen explorers.

The second problem I have is that there always seems to be air blowing from some where on the passenger side, unless i am accelerating. I can't seem to find where it is coming from but it makes a really annoying noise.

It is the 4.6L, AWD. not sure if that matters or not though.

Ford Ranger / B-Series :: 2002 - A/C And Heat Blows Through Defrost Only?

I have a 2002 Ford Ranger 3.0L truck that, all of a sudden, has a problem with the HVAC system that blows air only thru the defrost vents even when selecting any other vent levels (defrost, face/middle or floor levels).

I did find a thread on another forum regarding this problem, only it was for the 95-01 Ranger model years, yet they say that the 2002 Ranger is not the same as those earlier models.

Ford F-150 (2009-2014) :: AC Blows Through Floor And Defrost Vents Only

I have a 2010 f-150. Started having issues with the blend door actuator located behind the radio so replaced that a couple months ago and fixed issue. Now the a/c will only blow through the defrost and floor vents. I replaced the lower blend door actuator thinking that might be the culprit, but did not fix the problem. What the solution might be.

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.

Ford A/C :: 2003 - Air Blows From Dash Vents Then From Defrost In Cycle?

My nav. when I put the air cond on auto and lower the temp so the air comes on, it blows out the vents on the front of the dash like it should and is cold. Then after about 30 seconds give or take, I hear a door deep inside the dash shut, or open, then the cold air only comes out the dash vents that are the defrosters for the windshield.

Then I can make it go back to the front vents again by pushing the button on the heater control to make the cold air come out the front vents again, but then it does the same thing again. Whats going to need to be replaced/repaired?

Ford - Explorer :: Heater / AC Only Blows Out Through Defrost Vents No Matter What Setting It Is On

My wife's '02 Explorer has developed an issue with the heat/AC. As far as I can tell, the heat is hot when it's supposed to be hot, and the AC is cold when it's supposed to be cold. But, the problem is that everything only blows out through the defrost vents, no matter what setting it is on.

I know there are other threads on this type of subject, and I have read a lot of them. I thought I had identified that actuator gizmo as the culprit, but the more I read, it didn't seem like the symptoms for that issue are exactly like mine. I want to try and fix it myself, and I'd love to take the time to read everything on the subject, but warmer weather is here and my wife wants it fixed yesterday!

This problem reminds me of the time the vacuum pump went out on my F-350 and the defrost vents were all that would work. I wish this problem would be as easy to fix as that was.

Ford 7.3L Power Stroke (1999-2003) :: A/C Blows Through Defrost Vent Only

My 99' started o blow air only through the defrost vent today, and won't go through any of the other vents. I think this happens when your vacuum pump goes bad or there is a leak, correct? If so, how can I test these to figure out the problem.

Ford 7.3L Power Stroke (1999-2003) :: 2001 - AC Blows Only Through Defrost Vents

My 01 ac has worked just fine up until today. I got in this morning to leave the house and the air was only coming out of the defrost vents. I tried playing with the controls to get it to switch but couldn't. I assume its a vacuum leak, but where do I need to start looking?

Ford Super Duty (1999-2016) :: A/C Blows Form Defrost Only - Vacuum Pump?

Its hot in St. Louis and my windshield sure is staying cold (ac blows from defrost vents only).

1999 Ford F350 7.3 diesel 4x4 (4x4 lever on the floor). About a month ago, the ac starts blowing out of the defrost vents only. I assumed it was a vacuum issue.

Lines looked good; very plyable still. Canister looked fine. The vacuum pump on the pass fender well smelled burnt, so I replaced it. Got the new pump in and it didn't work. Checked the fuse panel and found two blown fuses, replaced them and the pump worked.

Here's my issues: if AC max is used, the vacuum pump stops working and air blows through defrost only . If the dash switch is in the off position and then turned back on, air blows through defrost vents again and vacuum pump will not work.

Is there a solenoid or switch to this vacuum pump that I'm not seeing?

2006 F250 with the dash controlled 4x4. I typically keep the front hubs locked on this truck. I have recently noticed that when shifting into 4x4 that the a/c or heat will switch from blowing out of the vents to blowing out of the defrosters. Any clues how to fix this?

Ford Excursion :: V10 - A/C Going To Defrost Under Load?

Well mine was. Checked all vac lines, 4wd was fine, tested with vac pump tested ok. So first I replaced the canister. Nope, actually happened more often. Pulled the 4wd solenoid that's mounted on the inner fender, rusted and split just above where the vac lines connect. I capped them and now my a/c is perfect, 4wd is out but for now I can live without 4wd.
