Ford Excursion :: A/C Automatically Switches To Windshield Defrost Vents
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.

When the blower is on, it automatically switches from vents to defrost vents on its on. Does it about every 4 minutes.... like it's haunted. Curious if this is something i can tackle or do i need to take it in...

My 2005 F250 just had the cab off in December for head studs and gaskets. Its a Crew Cab short bed FX4 so it has ESOF. When I engage 4x4 the blower will switch from blowing air out of the vents to blowing air out of the windshield defrost. Is a vacuum line plugged in wrong somewhere, or is one cracked? Trying to figure this out, its rather annoying

2006 f350 DRW King Ranch diesel with 94,000 miles on it. When I shift in to 4x4 the AC switches to defrost and then takes 2 min to return to the vents. I imagine this is a vacuum leak issue. Where to start hunting? I pulled the dash for another install and all lines were connected. I will say the vacuum pump stays on longer than normal when the ignition is first activated.
View 1 RepliesPrius (Gen 3) :: Airflow Intensity Level Changes And AC Switches To Defrost About Every 5 Minutes Or So
Even though my climate control system is not in auto mode, it still has a mind of its own. When I run my a/c, the airflow intensity level changes, and the system switches to defrost about every 5 minutes or so (even when there is absolutely no need for defrost). I continually have to set the system back to my comfort level. What causes this, and how do I fix it?

I have a 2003 Model F150 4x4 that has always ran good for me, and has only had minor issues ever since I've had it. Not too bad considering it has 266,xxx miles on it and running 100 miles a day on the original motor & transmission.
Here's my problem - my air conditioning will only blow thru the defrost. I can hit vent on the control panel and it will blow thru the vents, but if i hit max ac it switches to defrost. It has gotten super hot around here and i really need this to work correctly. I'm not very knowledgeable about this stuff (have worked more on older vehicles) so i guess I'll need a fairly detailed reply if possible. I have looked under the hood looking for messed up vacuum lines but haven't seen any that looked bad.
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.

This has been on going for the past year. The blend works fine. Fan speed works correctly. The selection for ac, max ac, etc., will only allow air through defrost vents. Vacuum leak?

Ford 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 F-150 - 1997-2003 :: Clunks Around At Low Throttle Especially Around 50 - 55 MPH
I am having a strange issue with the transmission in my 02 F150 with the 5.4, but it only happens when it`s cold outside and the truck is warm, typically after shutting off the truck and starting it back up (like if I stop at the store for something).
Basically, it clunks around at low throttle, especially around 50-55 MPH. Sometimes, it will act strange as I roll to a start, but typically it`s fine up until there. If I hit the gas it shifts just fine, but it acts up at constant speed/throttle.
I am hoping that its a sensor or something that's confused vs. needing a rebuild or new torque converter.
Ford Ranger / B-Series :: AC Just Sends All The Air To Defrost Vents When Apply The Throttle
I have a different issue than the typical heat on max ac. Mine is actually cold, it just sends all the air to the defrost vents when i apply the throttle. Comes back to the dash vents when I let off the gas.
I know that it's vacuum lines or solenoid, I just wanted to see if any guess on which specific line to check or any other info since I do NOT have a gauge to measure the vac lines for pressure.

The Throttle Body on my 2001, 4.6 L is making a strange whirring noise, when you puy your hand on the intake pipe, you can feel a slight vibration. The Truck idles and runs okay, with no codes. Giving it a little gas and the noise goes away. The last thing I did was clean the IAC with Gum Out Carb cleaner, the second or third time I've done this over many years, with no problems. I'm a little perplexed at the cause.
