Ford A/C :: 2002 Excursion - Air Blowing Through Defrost Only
I'm not sure if on my 2002 Excursion limited the air vents are controlled thru vacuum or electronically. Where to start. Where to even begin looking to correct this problem. I'd rather not have to pay the dealer prices unless it is something out of my league of fixing.

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 7.3L Power Stroke (1999-2003) :: A/C Only Blowing Out Defrost Vents?
As the title implies, that is my problem. Can't get the AC to come out of anywhere other than the windshield defrost vents. Y'all ever encountered this before?

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?

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) :: AC Quits Blowing Out Of Forward Vents And Goes Into Defrost When Activate 4WD
02 F250 with 7.3. When I activate the 4WD, my light comes on, the A/C quits blowing out of the forward vents and goes into defrost and no 4WD. If I sit and wait a bit, the air again blows out the front vents and the 4WD engages. I figure I have a vacuum leak somewhere in the 4WD system. Is there a common place for this to happen or do I need to trace the whole system down? Also my manual hubs has never been turned and of course they won't. I know better than use a wrench so is there a easy way to free them up or just go ahead and disassemble and clean?

I have a 2002 Ex with the 7.3. Every time I put it into 4x4, the A/C automatically switches to the windshield defrost vents. After a couple minutes it switches back the the A/C vents. I'm assuming that isn't normal.

View 7 RepliesFord Excursion :: Air Vents To Defrost After A Slow Transition When Put Truck In 4WD
I have a vacuum leak. That's clear. When I put the truck in 4WD the air vents to the defrost after a slow (15-20 s) transition. The only way I can get the air to come back to the dash vents is to disengage 4x4. Of course, the auto-lockers aren't working. I can trouble shoot the vacuum lines and find the leak. No big deal.
I've isolated it downstream of the vacuum reservoir. It could be the PVH solenoid but at least the reservoir side holds pressure.
My concern is the noticeably poor A/C performance. It cycles between kinda cool and kinda warm. I remember the A/C being ice cold a few weeks ago.
Could the vacuum leak in 4x4 vacuum lines be related to the A/C problems? I'm thinking blend door vacuum issues. But I can't even find the blend door vacuum lines.
How do I know if my blend door is fully open/closed? Are there any other place to look that can cut down on my troubleshooting?
Ford A/C :: 2002 - Air Coming From The Top Defrost Vents
I have a 2002 SuperCrew - I've recharged the coolant - I can fill the air coming from the top defrost vents.

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.

On my new to me 02 Mountaineer, the a/c and heater air on my climate control system is acting up. Everything is working as it should, except that when you direct air to the floor, the air comes out the defrost vents. I took the glove box out and when looking from the passenger floor towards the center, I can see 2 actuators that seem to be working. I was wondering if there were more than 2 of them, maybe one on the drivers side that I am not seeing, Didn't know that if maybe when one closed that another one would open elsewhere. As I said everything else is working as it should. Also the recirculation door is working as it should. Something else that I noticed is that the top port(#6) on the row of the vacuum hose plug does not have a line on it. Where I can get a diagram or picture of the hvac system.

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?
View 4 RepliesFord - Mountaineer :: 2002 - No Air Flow Volume Out Of Heat / Defrost Or AC Vents
My 02 Mountaineer doesn't have any air flow volume out of the heat, defrost, or a/c vents. The temp will change from hot to cold and the air direction will also change from floor, dash, windshield, etc. The a/c recirculation door also seems to be working. The fan sounds as it is running very fast, just not putting out any volume. What should I look for?

View 1 RepliesFord Excursion :: Air Blowing Hot Out Of Vents When Cool Outside
As the season has started to warm, I noticed when I have my air temp set to 60 and only using the vent and have not selected AC I have hot air coming out of my vents. After doing some research it appears that I may have a bad Air blend actuator, bad air door or something else. I took my truck to the dealer to get my fuel filter changed and asked if they could diagnose the hot air issue. Not being a mechanic I told the service mechanic the problem and he says the AC compressor always kicks in on fords even if the AC is not selected and maybe I have a leak and he seemed to think it more than likely was not the air blend actuator or blend door.
I told him I had no idea that the AC compressor always kicks in even with it not selected. I knew it kicked in for AC and for defrots but didn't think it did for anything else. He said since the 90's all fords did. Well I get a call that after diagnosing the system, they believe the freon is low. I just have my doubts and wonder now if I should've just tried to take the air door actuator off and test along with sticking something in the air blend door whole and verifying it was moving.
I was hoping someone that knows more than me can verify if the AC compressor kicks in even when it is not selected when I have the temp selector set to low 60 degrees. Does it make sense that I would have hot air blowing out of the vents with the temp set on low even when it is cool outside. All of my temp controls work moving from defrost, vent to heat as I can feel blowing out of the different zones.
