Ford A/C :: 1997 F150 V6 - Cold Blowing Only Through Defrost Vents?
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 (2009-2014) :: 2010 - Only Cold Air Blowing Out Of Vents
I have a 2010 F150 and now only cold air comes out of the vents. I have not changed the thermostat since the truck is not running hot. I have read that the blend door may be stuck. Where the blend door is on the 2010.

My 2001 F250SD 5.4L is doing something odd. When I have the A/C on and accelerate, it shifts from blowing out cold air from dash vents and goes to blowing lukewarm air out from the defrost vents on top. As soon as I decelerate or tap the brake pedal, it switches back to the dash vents and blows cold again. Even minor acceleration switches the air from blowing out the dash vents to blowing out the defroster vents.

2001 F150 5.4 4wd - AC not working but when I turn the temperature dial to the blue side and turn on the fan, super hot air comes out of the vents or wherever I direct the fan to blow (Floor, defrost, etc) I know it shouldn't blow ice cold especially since my AC doesn't work but.....shouldn't I feel a temp change coming from the vents when I move temp dial from the red area to the blue? It's max heat wherever I have it set.

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?

View 6 RepliesFord Super Duty (1999-2016) :: F250 - Dash Vents Stop Blowing Under Acceleration
My heater vents have been acting up. I have read that there may be a vacuum leak that causes the blend doors to default to defrost...
Where the vacuum line fails? I have ESOF 4x4 and that is still working. I think there may be a correlation between engine vacuum and my vents: at cruising or idle the vents work ok (not perfect) and under acceleration (less vacuum) the dash vents stop blowing.
I thought that the blend doors had their own vacuum pump, so I do not know why things change at different amount of throttle?
Passat (B5) :: 2000 V6 Heater Vents Blowing Cold
I took my 2000 V6 Passat into the shop because my heater vents were blowing cold. They tested the system and told me the following:
The hoses leading to the heating core are warm, but no warm air is leaving the heater core, indicating that it's plugged up with corrosion. They testing the coolant fluid and found that the incorrect coolant had been put into the system and that the fluid was carrying an electrical charge that must be corroding the aluminum portions of the system. In addition, the engine temp sensor is kaput and never goes up.
They offered a garden hose flush the heating system for a few hundred bucks, but warned that it is only 50% successful. They recommend replacing the heating core.
Prius (2004-09) :: No Heat / Vents Are Blowing Cold Air
I have an 06 Prius. I was driving my Prius today and I've noticed that my car has NO HOT AIR...
And this is Winter!! I was driving for about 20 mins and still...No Hot air...vents are blowing cold (cool) air.
I recently changed my condenser/radiator but I did NOT fill my condensor with the A/C gas yet. (could that be the problem?) But isn't the gas inside condenser is for A/C and not for the Hot air??
Any other stuff that I need to check to solve this problem?? (harness, fuse etc.?) It's cold outside and my car has NO HEAT!
Honda - Accord :: 2004 - No Hot Or Cold Air Blowing From Vents With Heat Or AC
Nothing will blow out from vents, with heat or AC. I checked the fuse under the hood and that had continuity, I checked the 7.5 fuse under the dash and that was fine. I also replaced the blower motor resistor and the blower motor with brand new ones. Also used a test light to make sure power was getting to the resistor and motor and that is all good.

Jeep - Cherokee :: 1996 - AC System Only Blowing Cold Air Out Of Defroster Vents
My 1996 Jeep Cherokee A/C system pushes cold air but out of the defroster vents not the A/C vents. Why this is happening? I suspect it is the slide switches for the A/C system but I am not sure and do not want to take the dash apart before I have some confirmation. I have checked the vacuum hoses with the heater/A/C system and they seem fine.

My problems in my ac begin last year around Summer. My ac was blowing hot and not cold and once it even blew some kind of smoke out of the vents. It only did that once and hasn't since. I went to good year and put some freon in the car. And it started to blow cold again and I was good for a while. Well I didn't need the cold air for the last few months till the heat started up again.

View 1 RepliesChevrolet - 1500 :: Driver Side Vents Will Suddenly Switch From Blowing Hot To Cold Air
Vehicle - 2005 Suburban LS, 5.3L V8; manual slide temp controls, separate controls for driver and passenger sides.Issue - In winter drive side vents will suddenly switch from blowing hot air to cold air. Just the opposite happens in the summer with drive side vents suddenly switching for blowing cold air to hot. Interestingly the passenger side vents operate normally. Sometimes if I stop and restart the vehicle the system will start working properly again but this does not always work.

View 5 RepliesFord A/C :: 2000 F250 Start Blowing Warm And Slightly Humid Air Then Suddenly Cold Air Come Back
I just bought a 2000 f250 diesel truck and am having problems with the ac. When I first turn on the ac it blows very cold and works perfectly but after about 5 or 10 minutes it will start blowing warm and slightly humid air for probably around 5 or 10 minutes and then suddenly the very cold air will come back. This cycle repeats over and over again and I'm not sure what is wrong.
