Ford 6.0L Power Stroke Diesel :: Air Conditioner Only Blows From Defrost Vent
My 2006, King Ranch, 4x4, 6.0's air conditioner only blows from the defrost vent. I have done some research on here, but haven't seen anything that identifies as a common problem. I did however, notice that this problem is stemming from a vacuum issue.

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.
View 2 RepliesFord - 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.

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 a Buick park avenue 1998, 3.8L V6 engine. the problem is: The ac vent on the driver's side blows cold air but on the passenger side blows EXTREMELY hot air. no matter how cold or hot you set the ac it blows at the same temperature on both sides. Florida heat is setting in and my passengers are melting. I am really hopping that is not something to bad and that I can fix it myself. Tip: this started happening after i had the alternator and the battery replaced.

Every time I turn my Ex off and start is again I have to turn my A/C completely off then hit the A/C and Recycle button to get air to blow out of the panel vents or it will automatically blow out of defrost vents no matter what setting it was on when I turned ignition off. Is there a blend door actuator/some sort of air diverter on these like my old Yukon XL had? On the Yukon the driver and passenger vents would blow hot and cold.
View 4 RepliesFord Excursion :: AC And Defrost / Vent Switching Back And Forth
I have to once and for all try to figure out what the heck is up with the AC and the defrost/vent switching back and forth. I have searched and searched and posted a few months back as well. But now that it's summer and 100 degrees out I've had a chance to test some more.
1 - I replaced both hoses going to the hubs up front.
2 - I am not sure how to test vacuum, but I did cap the hoses that lead to the hubs and still had the fluctuating back and forth
Looking for detail how to test for vacuum leak with a gauge directions ? What number is supposed to hold on the gauge and for how long etc...?
3 - It used to be that when I got to a high speed or RPM it would shift to defrost, but now I've noticed that once on the freeway going to work for instance and doing a constant 55-65 ( sub 2k rpm ) for about 20-25 minutes the vents hold fine. When I start to stop and go with higher RPM's it starts to 'break down' again. Could it be that there is a vacuum canister or pump ? I don't know ?? The diesels have a vac pump - do the V10's ? What can I check if there is no vacuum leak - what's next ?

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.
