Ford Super Duty (1999-2016) :: A/C Vent Control Up-gradation?
Sep 16, 2015
About 6 months ago I bought a 2003 F350 King Ranch to tow my toy hauler. Very happy so far. The one complaint I have is this...
The design of the heater / AC control module for this year of truck does not have a separate AC switch. There is not a separate button to turn the AC on and off and with a separate switch to choose which vent to blow the air through. For this year, I think 99-04, the vent selector switch must be turned all the way to the left and there are two AC Options... AC and Max AC. For both of these options the AC only blows through the dash vents.
Is there anyway to upgrade the in-dash unit to allow you to turn on and off the AC compressor while independently selecting, floor, foor / vent, floor / defrost, vent / defrost, etc... for the vents that the AC blows through?
I live in CA and it can get HOT... I would really like to blow the AC through the floor vents and / or the floor vents and the dash at the same time to provide more even cooling throughout the truck. Also, blowing through the floor vents would provide better cooling to the back seats.

My A/C, vent fan (blower motor) keeps going in and out. Does not do it all the time, but when it goes out, it will come back on after a few moments, but will not run full speed. If you try to adjust the speed, it just cuts off again. What is causing this.

My husband and I have 3 Excursions, V10, 6.0, 7.3 and I have a 6.0 250 crewcab. 3 of the 4 now blow air or heat from just the defroster unless your going at a slow speed.

I recently purchased a 2012 f350 power stroke. Love the truck but went out this morning and the air would only come out of the vents. I couldn't get anything out of the defrost or the floor vents? Truck is out of basic warranty so want to see if I can figure this out myself or if it needs to go in the shop.I've looked for a fuse but didn't see anything that ran an actuator door.

I have a 2000 f250 4x4 7.3 diesel. I had problems with my a/c and controls for sometime now. my a/c was blowing threw the defrost vent. I was told my blend door was bad. I bought a new blend door installed it,still doing the same thing. I was told to check my vacuum lines. I check them, they were bad. I replace my vacuum lines and my vac pump as well. that fixed my problem blowing threw the defrost vent. I can control my air flow from floor,dash vents and defrost vent. the problem I have, I not able to control my temperature when I turn my center from red to blue. It blows hot air and the air that is coming out of the vents isn't very strong at all.

I have a 1999 F250 V10 SuperDuty. Just recently I had noticed some gray foam material laying on my passenger floor. Then about a week later my air vent near the passenger window is whistling really bad when I have the air on. I normally have that vent closed. Is there an easy fix for this? My guess is that the foam inside has deteriorated and broke apart.

This is something to check, I found the vent line pinched closed on my 2000 F350 when I was trying to find out why it was leaking. When I was under my 2013 installing the hitch I checked it and found the same problem. The clip doesn't pinch it closed right away but it will happen if you don't move the clip.

I have a 2012 F-350 SRW with a 6.7 diesel. The other day I went to push the defrost switch and noticed it does not work. All the lights work in the switches, and the temp control works, but no matter what I push, defrost or floor, it stay in the vent only. Anything I can check??

2011 F350 loaded. Stuck on vent mode. Found actuator can feel it trying to move but something is stuck. Tried to remove the actuator but not enough room between the motor and a steel bracket welded in to the dash. (Not removable). Do I have to remove the dash ? (I suspect something fell inside and is stopping the big vent door from moving as i did pull the motor far enough away to move all the door except the vent door.

I have a problem with my vent selector on my truck. It's a 2005 f350 lariat. The vent is stuck on defrost, some times after a few mins I can get it to switch to floor but not always. I have replaced the pump, checked tank for cracks, disabled and plugged the auto hubs. The pump will shut off so I assume it's not a leak. I believe it's in the switching unit, can these be repaired? I found a lot of dust and dirt in the vac tank that had been sucked through a bad hub. I think it may need to be disassembled and cleaned. I have seen videos showing how to replace the orings in the older units. Are the newer style remote ones the same?

New to me 2003 F250 Super Cab 6.8 V10. Great condition inside and out. 68,000 miles. Began smelling fuel (gas) a few days after driving it 250 miles from purchase location. Traced leak down to the top of the gas tank. Staining was visible around the rear vent. Applied about 5 psi to the tank and sprayed soap around until I saw bubbles coming from a hairline crack at the rear vent connection. Its where the fitting for the hose comes out of the tank.
My first choice would be to hot weld the crack. I'm not very comfortable with the idea of a heat source near a gas tank. I'm not sure, but the heat from the plastic welder might be hot enough to ignite fumes? Second option is to try some industrial 2 part epoxy (PIG) and seal it with that. Is there pressure inside the tank, and if so how much? Can try this fix with epoxy or JB Weld?

so while replacing the rear brake lines in my 2001 F-250. / 5.4, the flex line that drops from the frame bolts to the axle through the axle breather threaded vent line. The friggin thing crumbled on me and now I can't find a replacement for it. Where I can get it or what it's actual name / part number is so I can call the Ford dealer and hope it's not obsoleted?

02 E450 Super Duty V10, C class a motorhome, 29000 miles. Cruise stopped working a month or so back. I searched this forum and managed to fix it with the info provided. It turned out to be the pressure switch on the master cylinder, the recall had been done. I replaced the pressure switch and the harness with an aftermarket one from the local auto parts store. It worked well for about 200 miles, it knocked off again on our road trip last week. It was working on the road and we stopped for breakfast and it didn't come on again, no light in the dash or anything.
When I ran the internal diagnostics on the first repair all the lights would flash when the buttons were pressed and the servo would cycle through at the end of the test as it should, based on the diagnostic instructions. This time when I run the diagnostic test the light will flash when I first turn the switch on (holding the off button down) and when I push the on the button but will not flash when I press the other 3 buttons.
I have not been able to find a wiring diagram for this particular truck, I've found 6 or so but none of them match my fuse boxes under the hood and dash.
I have no trouble lights on in the dash CEL or ABS. I'm at a loss what direction to take from here.

2014 f250 6.2........today on my way home from work I noticed my traction control symbol was on. It didn't say off under it like it does when you turn it off. About five miles down the road it was gone. What might of caused this?
Another thing I've been wondering is whats up with the carpeted inner fender wells. How long has ford been doing that and how well do they hold up?

I've got a '08 F250 XLT that the cruise control has become intermittent. It works most of the time but at times it will "go out to lunch" and not do anything. I've taken the controls from the wheel and didn't see any gummed up coke spills or anything there. It may not be anything but twice when it failed while on a trip I pulled over and shut the truck down. Started it up and the cruise would go back to working. Once I did this and it went back to working only to shut off in about 2 seconds but I was able to engage it again and it kept working. When it stops working there is no green indicator on the dash either.

My 1999 SD was originally a Work Truck without cruise. I'd like to add cruise of some sort (factory or after market), but also trying to keep the cost and difficulty factors low.
Have any of you SD drivers ever done this and if so, what you went through?

My fan control went out yesterday (hot day with no A/C), It comes back on at times, but if it's on three it may only blow like it's on one. What I need to replace??

Suddenly my cruise control dropped out. With some investigation I'm pretty sure it's that sensor or switch stuck to on position. Brake light is on. Checked the brake system and everything works well. Fluid is full all 4 pads replaced 2 days ago. Plenty brake power.
The question is: how can I bypass that switch to get my cruise control back? I see 4 wires coming out of the switch: red, blue, green, red/orange, green/purple. How do I do it?
