Ford Super Duty (1999-2016) :: 2011 - A/C Works Intermittently?
Jun 19, 2017
I have a 2011 F250 6.2 xlt 221k miles. I have an issue where my AC works sometimes and other times it doesn't work. On the occasion it will work kind of, meaning that it will blow cold for a few seconds (when the compressor clutch engages, but as soon as the clutch disengages I get warm air. My low pressure is at about 30psi and the high is about 140psi (seems low to me). When I bought the truck the a.c. didn't work at all. I pulled a vacuum and put the recommended 29oz of 134a in it. When it works its VERY cold. There doesn't seem to be any ryme or reason (temp, humidity, drive time) as to if it works or not. On occasion (not working) I have been able to turn off the a.c. for a couple minutes and when I turn it on it works.

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??

Over the last few years my power windows in my '99 Super Duty have started working intermittently. The problem seems to be with both the main controls on the drivers door and the control on the passenger door. Sometimes both of them have problems operating, sometimes just one. Does not make a lot of sense. Could I have bad switches or do I need to check something else?

So either these trucks have a super small window wash reservoir or there is something wrong with my truck. The window washer works just fine and then stops. The washer motor is still working but nothing coming out. I fill it up to the top again and suddenly it works just fine. The thing is that when I fill it up it only takes between 1 and 2 quarts of water. I'd imagine the recover probably holds close to a gallon so not sure why mine quits working and then is full after 1 to 2 quarts of water is added. Perhaps the pickup tube in mine is bent or something? No light or message on the dash...it just stops.

Just bought a 2010 f250 and I noticed that the warning chime works intermittently. I think this speaker or whatever it is also makes the turn signal noise because that sometimes is silent also. Where this thing is?

My radio, power windows and map lights all at the same time work intermittently. I have changed the relay. No blown fuses. Sometimes they all work and then for no reason that I can tell, they all go off. right before they all come back on (which you never know when it will happen) I hear a click in our around the fuse panel.

I just picked up this truck and have found my first undisclosed problem. The A/C only works on MAX. If you turn to any other setting, regardless of selected temp, the air blows hot. And I mean full hot! I was thinking the control panel assembly is bad?

I have an F-250 Ford, 2006, 6.0 turbo-diesel. Started noticing that my heat only works while running at 70 mph or more and the turbo is at around 15-20 psi. Now that it has gotten cold it is definitely an issue. Truck does not overheat, I am not able to feel heat on the hose after control vlave and I do not feel any vacuum on the line (grey) to the control valve. I have checked for leaks, changed out the fill cap, checked anti-freeze level, pulled control valve just to verify its position when opened (which it seems to stay open). It's getting really cold in the cab of that truck now.

My 2001 f350 a/c blower works better on a/c compared to max a/c . When I turn the selector to max a/c it makes more of a blowing noise but less air blows out of the vents though. When I select plain a/c it makes less noise but blows more air out of the vents. What is wrong and how to go about fixing it is 93 here today and won't get much cooler over the summer months .

I have a 2000 f250 7.3 and the cruise control works when only when the engine is cold. Once the truck warms up, cruise will shut off and not reactivate. I have no lights on on the dash new clutch safety switch a new sensor on the master cylinder horn works and have had a scanner hooked up and compared the electrical values of the buttons pushed to the spec.

The power mirrors on my F-250 works halfway. I can get them to move inward but not outward. They also will upward but not down. These are both mirrors. Could it be the switch?

1999 F250 .. Blower works some times then for no reason stops. When it works, I have all speeds, it makes no odd noises. I shut the engine off and then it does not work. I have power to the blower motor even when it is not working. I doubt it is the speed resistor module because that is not used in high speed. I've taken the blower motor out of its housing and pulled the resistor module as well. I find nothing wrong, power it up and the blower works. I put it all back together and it does not work.

2002 sd 7.3 4x4. When I start up engine and put truck in any gear I get nothing but the ugly clicking sound when I shift back into park. Turn off engine and restart, everything works as normal. Doesn't do it every time 4-8 normal start ups then a bad one. Brought it to a tranny guy, head scratcher for him. Any other solution before I start changing parts?

4x4 dash indicator light stopped working on my father's 2002 F-350 V10 about 8 years ago and I'm trying to see if I can fix that problem.
Unsure exactly when this problem began, but when a mechanic replaced front wheel hub about 8~9 years ago, automatic hub lock stopped working. Back then, I thought that is why 4x4 indicator stopped working.
When I removed hub to replace ball joint 2 years ago, I discovered yellow O ring was not installed and that was the reason why automatic hub lock stopped working. Now I installed new O ring and vacuum seal, automatic hub lock works. However, 4x4 indicator on the dash still does not work.
I thought may be bulb went out, but when I tested dash bulbs with self test mode, 4x4 indicator light turns on. Also I believe that lamp is LED not regular bulb.
When I pulled DTC, I get P1879 - Powertrain Transmission Transfer Case 2-Wheel Drive Solenoid Circuit Failure. From what I searched this indicates failure at vacuum solenoid for front hub locks, but it is working fine. What is going on?

I have an 01 f350, my reverse lights only work when I hold up my shifter, like its almost into park. I think my reverse light switch is bad, but I don't know where its located.

ESOF not going into 4wd at all, except once in a blue moon... for a few times. All relays and fuses tested, swapped with known good units.
NO 4x4 light. so its electrical related. My hubs function like they should. when they are told to. I recently just swapped esof motor/gearbox on the TC. Worked 2x in the garage, went for a spin down the road, went into 2wd and stayed, wouldn't go back into 4hi brought it back inside, dinked around with resetting the GEM fuse. started working good. drove around and switched in and out of 4wd like 20 times no issues. next day, tried to go back into 4wd. nothing. Bring it back in the garage.
CURRENT DIAGNOSIS: Siting inside right now, If I flip the switch, I don't get anything. normally, that triggers the vacuum pump to suck hubs in. That doesn't turn on, the relays under the hood don't click. so it seems I am back up to the switch or GEM, or wires between.... Any test layout for how to test the switch in the dash? seems to be fairly simple, but I just wanted an exact view of what i need to test.
