Ford F-150 (2009-2014) :: AC Fan Noise As Something Flapping Around Inside The Duct
May 9, 2011
It is finally getting hot here in Texas and I turned my AC on Max the other day. It has a sound like there is something flapping around inside the duct work or something like that. Like a flag whipping in the wind. I tried feet, defrost open and closed loop etc and the noise is always there. It is really annoying when it is on high speed. Also, I did not notice the noise during the winter. Is there some where that leaves or something like that can get into that might cause this type of noise. The truck is a 2010 FX4.

Since most of us on this forum drive pick-up trucks, we're all accustomed to them riding, well, like a truck. We fully expect them to bounce around a little bit, right? However, one should not expect to be annoyed by noises inside the cab. For instance, my passenger seat bounces around like a baby's bouncy chair, even when the road is smooth. Surely, I'm not the only one noticing this! How do I shut-up my passenger seat???

I have noticed on my 2013 F150 Eco that I have seem to always have a oil type smear. on the inside of my windshield. It is very hard to clean. Looks like the ones I would get when I smoked many years ago. My Boss has a 2011 F150 ECO and we have two others in our company. We were talking at work today and it seems all 4 trucks are having this problem.

My 2010 F150 super crew cab is rusting from the inside out on both cab corners. I purchased my truck about 3 years ago with 75,000 miles on it. After about 3 months I noticed the 3rd brake light was leaking. I went to the dealer but they wouldn't warranty it due to the mileage. They did acknowledge that there was a problem with the 3rd brake lamp leaking and was willing to sell me new parts. So I repaired that ASAP. I don't how long is was leaking prior to that. Fast forward a couple years later the corners are starting to bubble. I am assuming this what caused the cab corners to rust.

Opened one of the rear doors on my crew cab and there must have been several gallons of water sloshing around inside the door. Shook the door a few times and water started draining out both corners of the door seam. After about an hour (I told you it was a lot of water) it seems to have stopped draining. Now I'm wondering how long this has been going on and what the inside of the door looks like by now.

I own a 2011 lariat with 500 miles. We have had several days of rain and I am getting alot of rust spots on my driveway always below and inside the right front tire. None in the rear or left front. Dealer said not to worry about it after they looke at the area. They said it is the new metal forming surface rust. There is a skid plate which seems to cover wherever the rust is starting. Should I demand that area be undercoated.

I have lots of info these manifolds. Have gone through four including both sides twice. This last time it seems the manifold has a crusty residue on the inside. The mechanic says it may be a bad head gasket.

I have a 2010 f150 supercrew 4x4 with 8.8 3:55 nls rear differential. my driver side tire has a wobble to it it is wearing the inside of the tire. i have replaced the driver axle shaft with new ford oem shaft put in new axle bearings and seals on both sides and have replaced the spyder gears and i still have the wobble I don't know what is going on. the wobble is more pronounced when the tire and rim are bolted to the shaft only without the drum and caliper attached. with caliper and rotor attached i still have the wobble just not as bad however the tire wobbles going down the road more noticeable between 20-45 mph.

My exlporer heat and A/C system has been making "ticking or flapping" noises for sometime. So, to make it stop I would turn fan to full blast and it would stop and the heater would function fine after that. Last week we hasd a warm spell and I switched to A/C (going through the same process to stop the noise). All was well until I tried to switch back to heat after the warm spell, and now I get nothing but cold air. The noise will only stop when I turn the temp dial to the cold side, but either way, all I get is cold air. Is this something I can fix, and if not what am I looking at for repair cost? I'm freezing!!!

I have a 2004 F150 XLT super crew cab. I bought this used with around 99,000 miles on it. There is a plastic / rubber two piece cowl panel between the hood and the windshield. There are little rubber type material tabs on the outer edge between the fender and the cowl panel. They are there on my truck but they have started to come off. I have noticed that when I get up to roughly 45MPH and over I get a flapping wind noise on the drivers side of the vehicle only. I thought it was that little rubber flap because it came off completely and the noise got a little worse. I super glued it back on but the noise is still the same.

I've noticed a few times now on my wife's car when I am driving it around 80 mph there is a some-time flapping or low-thumping noise from underneath the car. It only happens up around 80 mph. My wife says it's a feature to let me know to slow down . I originally thought maybe I had a plastic bag trapped under the car or some loose trim but looking underneath hasn't turned up anything. The only other thing I can think of is maybe it's just a strange aerodynamic quirk of the car that causes the noise.

What makes a flapping noise in the engine when car is started/restarted? It sounds like a dull slam of a fabric covered lid, slamming shut!

I picked up my car from the dealer today and driving home once I hit over 70 on the interstate the car started making a slight noise. It sounds like a piece of cardboard sort of flapping in the wind. It feels like it is coming from the engine bay around the level of the accelerator. What it might be?
I popped the hood and nothing was left inside that I can see. The only thing that seems loose is just the induction scoop. It looks like on the side there should be a clamp or something to hold it in place, but it moves freely. I can't find any good stock shots to see if there should be something.

I bought these lights on ebay. It was direct replacement for stock and it has Fan and ballast built in. Light is good and all good but im hearing some low frequency humming noise when im inside car and waiting in any traffic light.
I also opened the hood and tested it is there but less. Im hearing more in cabin. When i turn off the lights its gone. Is it the fan ? How to control it.

I have a 2009 Subaru Impreza Outback Sport with 42k miles. I purchased the vehicle about 2 weeks ago, and since the day I got it i noticed a vibrating noise inside. It is not too loud and so it did not bother me at first, but I have become increasingly more and more annoyed with it. It is constant, as long as the engine in running. It varies in pitch depending on the rpm of the motor, but never goes away. Does not change with the air conditioner on or off, and does not change with the radio on or off. It is not engine noise, and is not noticeable outside the vehicle, but it loud enough that it is heard by all in the car.I took it to the Subaru dealership and they could not pinpoint the noise, and said that the vehicle was sound.I then had a mechanic friend look at it, and he traced it to under the driver's side kick panel, but could not pinpoint it further.

Today I was at a light, stopped with brakes on. Heard weird loud flapping noise like when you put a playing card against spokes of a bicycle. Smoke appeared. No warning lights so I thought it was the car ahead of me - especially since the noise stopped when I pressed the gas. Drove 11 miles home, 9 of them uphill. No problems. Parked for about an hour. Then drove about 4 miles and was again stopped, again the noise (not so loud this time) and some smoke from under the hood. I was right next to a gas station, pulled in and very nice attendant checked fluids, etc. No problems found. He spilled a bit of antifreeze when checking the radiator level. I then drove straight to a Honda dealer. They have proclaimed it a broken radiator on the basis of a brief exam and a sighting of a bit of antifreeze. No leaks anyplace, car was no overheating, the vehicle has less than 50 thousand miles and is regularly maintained.

I just purchased my new Elantra 2 weeks ago. A few days later, just after I started it first thing in the morning, it began making a loud flapping noise (seemed to be coming from under the hood). It's been doing it every morning since. The dealership said they couldn't hear anything unusual (after keeping it overnight, then starting it up first thing the next morning).

Thought it was another AC flap that is playing up but it was the small plastic flap next to the tyre that was giving me the headache.
Still, could not find the rattle at the rear which i think is caused by the underfloor storage compartments. Thats for another day.

I have a 2012 and just passed 14,500 miles.
I was driving home recently and heard a flapping type noise on the drivers side and thought something was stuck in my undercarriage or even in my tire and the wind was causing it to flap. I pulled over to check, saw nothing, so I kept driving home and stopped into my local Toyota and they didn't see anything loose or out of place. We went on a test drive and of course, there was no noise.
Later that night as I was driving, it started in the middle of my drive, I parked and when I drove again, no noise and I haven't heard it since; this was 3 days ago. I thought it was just at highway speeds, but I've heard it at different speeds.
