Ford Super Duty (1999-2016) :: Hissing Sound From AC That Lasts For A Couple Of Seconds Then Goes Away
May 22, 2014
I used the a/c for the first time this year on my 2013 F250 and heard some noises I don't remember hearing before. When the a/c(or defrost) is on every 12 sec or so I hear a hissing sound that lasts for a couple of seconds then goes away. Is this the compressor cycling and if so is it normal to hear it inside the cab?
I know it has to do with the a/c because if I shut it off as the hissing sound is being made the sound will instantly stop. Other than the noise the a/c works fine and blows cold air. Also, if it matters I have the standard control panel, not climate control.

Minor noise, and it might be normal. When I have my air on, I get a sudden hissing noise for about 2 seconds, and it happens once every 5 min or so, almost to the second. Not that loud. like a blow-off valve noise, almost. Sounds like it's coming from the passenger dash area. No other ill affects that I've noticed. Not to be confused with the popular wind/intake whistle that some have. Any theories? Almost sounds like a drop of water landing on a belt, and spinning dry. But it happens on dry days too, I think.

I just recently purchased my 1999 ford F-250 superduty V8 5.4 5 speed with 144,00 miles and I'm having a issue with the clutch pedal sticking in and then it will pop out after a couple seconds. It will stick more when I come to a light and have my foot on the clutch but the pickup drives fine and there is no slipping of the clutch. I have never experienced this issue before in any rig I've owned. so I'm a little lost at the moment.

I own a 2000 Ford F-250 5.4 Automatic. It tows my 5th wheel trailer very good. On our last trip it suddenly experienced the "check engine light" effect.
The light turns on randomly and either goes of after a couple of seconds or it doesn't go on when I restart the engine.It is mainly annoying, but when in towing it really hurts, because the engine switches into an emergency mode and stalls.
I read that the engine uses only 4 cylinders. I read many articles on the web about that light, but I couldn't find a solution. The thing is I brought the car to several repair shops but none read a code from the computer.
I think it's not a real fault but a misreading or maybe a cable that's grounding? The problem is, I can't bring the car to a repair shop, because there is nothing wrong with the car. How can I find the source of the problem?

Have a Whistling or hissing sound while accelerating? My 2015 6.2 seems to make this sound while under load. I took to dealer and they claim its the throttle plates not closing all the way. Claims this is normal, but to me it is annoying. Just would like to know what others think.

2005 6.0l PSD. Driving flat road pulling 8K trailer. Not pushing it at all. Sudden air hissing sound on (seems like) passenger side of truck. Black smoke pouring from tailpipe. Check intercooler pipe and is ok. Can't see anything that is loose. Only 8 miles to the campground so limp down the road at 30 MPH which is all it will do. Hissing sound is remarkable predictable in that it is repetitive every 5 seconds or so. Lasts for maybe 2 seconds then stops the repeats.
There is no turbo boost either on the dash gauge or the Scan II gauge. Shutting the engine down, there is no turbo wind down. Scan II show no codes. Check everything I can reach and find nothing extraordinary. Tried starting a driving it today and had boost for a minute only then nothing. Blowing white smoke too. Check the oil and it is oil. Check the radiator fluid and it is oil free. Running low on fuel and wonder if I have a water in the fuel problem. However, don't think that should effect the non functioning turbo...

I have a 2005 Honda CRV with 139,000 miles that recently developed a miss. It usually does it while holding steady at 50 mph but only lasts for a couple seconds. If it misses may do it once or twice and then nothing the rest of the day. Had the dealership put it on the computer for a reading and they said it's showing no misfires and is running properly. Plugs have been changed other maintenance performed and have had absolutely no issues until now.

2012 F-250 6.2 gas 4X4 SC/SB: when I run WOT, or near that, from a slow speed, I hear a short "hiss" between the 1-2, 2-3, and i think 3-4 shifts. I can also feel that the engine eases up quite a bit during the shift, and it is kind of a slow, soft shift. It has about 2,000 miles on it. I bought it in March 2013 as a leftover (great price!). The door sticker says it was manufactured in 4/2012, so it sat on the lot for quite a while before i bought it. But i don't remember it doing this when it was newer (~500 miles).
With the lite weight of this configuration (it is an XL so it isn't even carrying around 4 speakers ha ha), and me rarely carrying a very heavy load (yet) or towing anything, I rarely have to step on it very much in normal driving... it hardly ever gets above 2,500 rpm unless I am just running it faster for fun.
The hiss and slow shift happen at any transmission temperature. Of course, it never has been above the left side of the "gear" pic on the temp gauge, where it always is after full warm-up. Well, I'm hoping it is just shifting soft like this because it has "learned" my lite-foot driving style (even when I'm in a hurry of course the engine rarely has to work very hard).

Bought a 2014 SD 4x4 in December of 2013 and this is the second time the big girl has been to the shop with A/C problems. First time it was the evaporator about three or four months ago. During the last few weeks of the summer I began to smell something strange (like band-aids) when the A/C was on and it lingered until the next re-entry. ALso, began to hear a slight hissing noise when the compressor was kicking in and out. They replaced the evaporator, smell remained as they said it was the refrigerant I was smelling. About two or three weeks ago the smell got slightly "larger", and last weekend she would not cool. This is the fourth time shes been to the shop with other problems such as the My Touch system..............

I have a 99 F350 with a V10. I just replaced all the spark plugs and a bad coil which solved the very bad misfire I had going on. I also just changed the fuel pump and fuel filter.
When I start the truck, it idles just fine, nice and smooth. After sitting there for a short bit, maybe a couple minutes, it starts to idle rough, not so rough that it's about to shut off, just a little rough. This lasts maybe a minute and then goes back to nice and smooth and stays that way.
I've thought maybe the EGR valve or Idle air control valve but I'm not sure if I'm way off or sort of close.

I have a 2015 ford f250 xlt crew cab, 6.2, fx4 with about 1200 miles on it. My questions are, I have noticed a hissing or whistling noise while accelerating. I took to dealer and was told it was the throttle plates not closing all the way.I was told they all do this. Normal? Very annoying noise with windows down. Another noise I have been having is the brake pedal makes a popping noise while applying pressure to brakes. Dealer said brake pedal assembly was out of alignment. They said was out of alignment 1/8". After adjustment within a few days popping started again.

Have a 06 f350 just rebuilt the engine. Started up ran it down the road a couple miles and lost low side oil pressure. Got back to the house and will not start again so put a gauge on and it only has 3 lbs after cranking for 10-15 sec. Pulled the balancer and lpop cover and front cover had some deeper scoring then before. No noticeable stuff in the pan or filter. Changed out the front cover and lpop. Still has only about 5 psi.

Looking for some input on a recent "hissing" noise coming from eng compartment. It's only noticeable during initial acceleration, and sometimes at the beginning of gear changes. I am assuming its tubo and/or exhaust related, as I've noticed a strong exhaust odor in the cab as well. I wasn't under load when the problem started but i was under rapid acceleration. Not noticing any fluids or oils leaking. No warning lights have tripped, as of yet.

I've got a 2006 f250 with 160,000 miles, trans was rebuilt by previous owner about 10,000 miles ago. The tow/haul light started blinking yesterday, only blinks for first couple of minutes of driving and then stops. Service engine light popped on today as well. Won't have access to a code reader until tomorrow, but looking for some preliminary info...

Every once in a while, I hear a sound coming from under my car, possibly the passenger side, that sounds like I am pulling a tin can around. It only lasts about 3 seconds. Sometimes I'll hear it when sitting at a red light, or accelerating from a complete stop. Then the sound disappears. This doesn't happen all the time, but I do feel like I'm hearing it more often as time is going on.
I did a little research online, and some say it could be a rock under my heat panel, but that seems too easy. I don't have any issues with shifting gears or accelerating.

2006 Sonata LX. It's only on a cold start up and lasts for about 30-45 seconds tops..and then it goes away. Car has 74k on it. Treated well. Only use synthetic oil and no check engine lights. Last oil change I put 5w 30 in it. I know it says to use 5w 20. Could this be the problem?

My F350 idles fine but every 10-15 seconds it mis fires. When asking it to go up hill it sputters and seems to loose power. It runs fine until asked to work hard. Not really sure which direction to go in first.

'03 F250 V10 SuperDuty.
Ok...I hadn't driven my SD for over a week...maybe like 7 days. Get in...and turn the key to the 'On' position. Wait for the computer to cycle on (I just like to hear it)...and then fire up the V10. It's a HOT day...so I try and open the electric windows, but nothing happens. Then...I notice the radio is not on either. What the heck??? Ok...about 30sec or 1min passes and the windows are now working and the stereo is on. Some kind of weird time delay...???
So...here is the catch of it all. I drive to the local hardware store and all seems fine. Do my business in the store...and jump back into my SD. Fire it up...and everything is working. The windows or radio did not have that "time delay". Now...I am really confused.

Worked with the 6.0s on my ambulances at my station but this is my first personal diesel. Starting about a week ago my 2006 F350 with 88k started having longer cold cranks, around 10 seconds with some hiccups on the way. I checked the FICM Voltage with a multimeter and on my scan gauge II, it has not gone below 47 volts. I am above the 500psi on the ICP, and around 35% on the IPR Duty cycle. The FICM is also synced. I know this is a big topic with these 6.0s but normally one of these things are an issue, where as mine are in normal range.
