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 A/C :: 1997 E350 - Hot Air Blowing Out Of Rear Floor Vents / Blend Door Won't Function
My 97 e350 club wagon is doing something weird. Front AC wont go to Max Air, the blend door wont function. Can hear vacuum trying to work. Rear Unit is on Heat even though Front is on AC and blows hot air out the rear floor vents. Hit some high water going too fast about a year ago. Next day, this started happening. Rigged up blend door so air flows through vents.

My dad just got a 2012 Camry LE, with the 4 cylinder engine. The heater seems to be working fine except for the floor vents. When I select that option on the HVAC control, I can hear the fan working but there's absolutely no airflow coming out from under the dash.

OK.. 2005 F150 Lariat. Air conditioner worked on the way to work, went to drive home, air not blowing out the 4 main dash vents. Blows cold out the feet, and redirect SEEMS to be working, just not blowing at all out the main vents in the dash?
Even if you adjust the temp to where it should be blowing warm/hot air, it will not blow out the main vents.
Ford 7.3L Power Stroke (1999-2003) :: Floor And Defrost Work But Dash Vents Not Working
The floor and defrost vents work. It just stays on defrost when you try to use the dash vents. The actuator seems to be working fine. I can watch the arm move through all the motions. and I cant find ANY vacuum leaks. Yes I looked at the hubs and under the hood. May be moving to alaska and kind of need my heater to work properly. . . .

My car: 2008 Prius (base)
Here is the problem: All of a sudden the two middle vents in the dash stopped blowing. I have played with the settings - on, off, all the way hot, all the way cold - nothing from the two mid vents. The left and right vent blow with no problem. There is also cold air coming from the vent near the windshield - just the two middle dash vents are not functioning.
What I have done so far: I had it looked at by a mechanic who I trust. He said there is a small motor (he called it a servo motor) that controls that middle vents (open/close). He said that had gone bad. He manipulated it so that the air blows out of the vents now and said not to change any settings until I am ready to replace the part.
Ford A/C :: Shifts Blowing Out Cold From Dash Vents To Lukewarm Air When Accelerate
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.

I recently installed an egr delete and ever since, my vents have been stuck to the upper dash no matter which setting I put on. The vent will push the air conditioning, regular air and heat all the same. I have checked the fuses and they are all good.

2002 - 7.3 lariat, my a/c stays on max because of the recirculating effect. When I get in the next morning during summer of course, my dash vents take a few seconds to begin, default defrost till that time passes. Sure I know about leaks and redone all that to make my vacuum hubs work correctly. It didn't begin till later not right after that overhaul.

My mother's 2000 E150 van isn't blowing any air out of the vents. It doesn't work on high. I can detect a small amount of air coming out of the defrost vents and the floor vents when it is on high. I just replaced the resistor after finding that it had melted and still no air. My mother said that the a/c would go on and off when she hit bumps.
Do you think maybe the fan isn't grounded so the resistor overheated and caused melting in the resistor plug? The plug looks exactly like the one in the middle of this webpage. Same pin melting location also. Ford Blower Motor Resistor Pigtail Replacement...
I ran out of time to work on my moms van because I am in law school and live 2 hours away. Assuming ground, blower, and fuse are all good (I'm checking those friday), what else could be the problem?
Ford A/C :: 2000 Expedition - No AC At All / All Vents Blowing Hot Air
On my 2000 E.B. I have NO A/C at all. All vents on the dash, regardless of vent, floor, defrost, ETC all blow hot air, even with the A/C on Max A/C. Also, all the rear vents for the rear HVC blow WARM air as well. I have no A/C in the back either. I don't hear any flopping around under the dash going down the road and I have checked the A/C compressor with the unit on Max A/C and the clutch appears to be engaged and the compressor appears to be operating normally.
I have NOT YET checked the A/C lines or dryer to see if they get cold, I will check that tonight, but I expect them to be getting cold because the Compressor does not cycle on and off, it stays running pretty much all the time. It clicks off once and again, but not very often at all (such as the case would be if the system was low on freon).
So, if the A/C lines are getting cold (if they are not, I will know my problem is compressor related, likely anyway), what this problem could be? From what I've read, if the Front blows hot, yet the rear blows cold, it's a blend door actuator or broken blend door, but that is not my problem. I have no A/C at all, everything blows hot.
Ford 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.
Regal :: 2000 LS - Dual Zone Climate Control Stuck In Floor And Mid
I just installed an aftermarket blower motor in my 2000 Regal LS (175k miles) with the auto/digital dual zone HVAC. All works fine with the blower motor. But when I hit the air flow button on the main unit. The airflow only vents out of the floor and very faintly from the mid. Regardless of whether I switch from floor, mid or window, airflow still vents out of the floor mostly. I know I need to recharge my ac, but I wouldn't think that that would be the cause of the problem I am having with airflow location. Do I need a new control unit??? Everything else works fine with the ac unit. What gives???

I have a 1989 towncar. The blower motor works in any selection (vent, panel, hi-low, mix, defrost) but does not work in the "floor" position. It also turns off in the off position as it should.
I changed out the entire climate control assembly with another one from a junkyard. I thought the function selector electrical switch might be bad. However, the blower motor still does not work.
