I've already had the blower motor replaced, which did not fix the issue like fontaine_erik. It was not on back order, I only had to wait a week. It actually sounds like fontaine_erik and I may have the same issue. Please let me know if you get the issue resolved at your dealership.

Thank you all for clearing this up for me!

I have two conflicting replies. Anyone else have an answer?

It seems to be an electrical frequency noise rather than anything else. There is little variation, it is a constant pitch and tone. Once you turn the blower to 3 the noise comes on and it does not vary. There is no chirping with mine. I have experienced before it not making the noise and once I turned a corner it started making it. It is either occurring when you turn the blower to 3 and have heat on above a certain level, but does not occur if the heat is set below a certain level or i turn the blower down to 2. I've now found that if the car is turned off, then I turn the ignition on without starting the car, and try the fan at 3 with the heater setting set to heat, that it does not make the noise, but if I turn the dial to 4 it starts making the noise. Having already had the blower swapped out, I'm thinking there must be something electrical making the sound maybe? The greater strain of power from the 3 setting on the blower and the strain of powering heat; producing an electrical noise/tone ???!? I'm really hoping someone else has experienced this on this forum, as I really need some help with this one!

Ford Fusion 2010 SE I have had an issue for a while where if you turn the blower to 3 and the thermostat dial is on heat, then I get this high pitched noise kind of like a dog whistle or high pitched electrical frequency noise. If I turn the blower down to 2, it goes away! Or if I turn the thermostat dial down to almost mid point it goes away. I believe the noise is still there at 4, but the noise of the blower drowns it out. The high pitch noise makes it unbearable to be driving with the heater blowing on level 3. I had the blower motor replaced today thinking that would fix the issue, but it did not! I'm now at a loss as to where the noise is coming from if it is not the blower? Anyone have any ideas or experiencing the same issue?

Finally got it resolved. Here is the story. I decided a couple of weeks ago to pursue this issue again at the dealership, mainly because it was annoying my wife. I reminded them of their advice to test another car. First they had me drive around with a mechanic in the back seat listening for the noise, and then they had me do the same in another Fusion 2010. The mechanic agreed that he could actually hear the noise and was able to replicate the sound when stationary by rocking the seat forward and backward. The sound was not present in the other Fusion. Therefore they decided to take the seat panels off and fiddle with it and investigate, which they did for quite some time. The eventual report from them was not good. They reported that they could replicate the sound in the drivers seat too, and that there was nothing to be done but for them to contact Ford again and ask for advice. They said they would recommend replacing the seat track as that is where they believed it was coming from, but I had already had that replaced. I left the dealership a little dismayed that I had affectively been cast aside by the dealership and by Ford, who in their morning email to the dealership simply said the same old 'Some rattles are normal in a car'. The dealership apologized and sent me on my way. but..... On driving home I noticed the rattling noise had gone. I got home and drove a familiar route that always caused the noise, and even had my wife do the same. The noise has seemingly gone altogether! I put my hands on the seat and tried to rock it as the mechanic had and the seat seemed a hell of a lot firmer and tighter in its spot. At this point I believe it is fixed, although even the dealership does not know exactly what they did to fix the issue. Good luck to anyone else who has the same issue, I wish I could tell you exactly how to fix it, but I can't! :shift:

This may be a dumb question, but is the trunk on the Ford Fusion 2010 meant to push the trunk up and open, or is it supposed to only unlock the trunk so you can pull it open. I know on other cars when you hit the trunk button the trunk flies open, where as mine simply unlocks, it does not open. Is this just how it is with the Ford Fusion 2010? Is that what trunk release means? If anyone could shed some light on this, it would be much appreciated!

Well I've tried to ignore the issue but it's not going away, so the hunt is back on. Like I said before the rattling is to do with the seat as it stops as soon as I put a little pressure on the passenger side seat pushing it away from me. I only have to apply a little pressure for the noise to stop. I've had the seat track replaced, so it was not that. It isn't the seat belt against any plastic, or any strips around the door, as it appears to be isolated to the chair, judging by the fact it stops with a little pressure away from me. The dealership has said that Ford does not understand what the problem could be other than the seat track that was replaced. They have suggested that some rattling is normal, and that I should come in and test drive another fusion 2010 and see if the noise is present. I guess that is my next step! I will be calling to make an appointment to test another car out for the noise. It was actually my wife that pushed me into pursuing the issue, as she complained that it was annoying her now! If anyone comes up with the answer before I get to it, please let me know! :sos: I'll keep you all posted on my progress!

OK, so today was not a good day with the car. They replaced the seat track, but that did not cure the rattling noise. So they have put in an enquiry with Ford. On top of that they managed to scratch the plastic panels by the door when they took the seat out. Now they have to replace those panels and still come up with a fix for the noise. On top of that, when they replaced the track and put the seat back, they did not recognize that the seat had to be reprogrammed into the system. When I picked the car up the first time, the passenger airbag off light was on all the time. They have fixed this now. Just waiting on the replacement parts for the ones they damaged, and a hopeful idea to fix the rattling problem with the seat. The rattling is to do with the seat, as while I am driving, if I put a little pressure in any direction on the seat with my hand, the rattling stops! The saga goes on....

Just got back from the dealership, apparently the issue is the seat track. They have ordered a new seat track and told me it would take a day's worth of work to replace it once the part came in. Also, just before I took it in today I received a ford safety recall notice for : 10B15, which apparently is for a PCM reflash. They did the recall issue today, haven't really noticed any difference! Here's hoping the seat track doesn't take forever to come in, as I ordered a replacement hubcap a month and a half ago, and was told today it would not come in until June or July. I really hope the seat track doesn't take that long to come in, and that it's replacement actually fixes the issue. I'll let you all know once it's been replaced!! :waiting:

I have booked it in for Monday to be looked at by the dealership. The rattling sound was not coming from the seat belt, as even when I held the belt across the seat I could hear the rattling of the seat. I don't really know how to test the seat track, I know that if I move the seat all the way forward, or all the way back, it makes the same noise. I'll let you all know what the problem was when I've been on Monday! :sos:

I will have a look at your suggestions tomorrow and see what I come up with! :shift:

You were all so helpful before that I decided to return to call upon your wisdom once again. My Ford Fusion 2010 has developed a rattling sound in the passenger side seat when no one is sat in it. I thought originally that is was the passenger side door, but when the rattling is occurring, if I place my hand on the side of the seat and apply a little pressure in any direction the noise stops. The noise does not occur when anyone is sat in the seat, just when it is empty. Does anyone know if there is a TSB for this, or have any idea what it could be? I'm thinking about taking it back to the dealership next week for them to look at.

Last update on the issue: Today I took it in for the starting issue and to have the defect ridden panels replaced. I can now say goodbye to the feelings of dread every time I drove the car knowing I had those defects spoiling my new car. The car is now the way it should have been when I first bought it. Thank you once again for all the encouragement to pursue the issue. My local ford dealership replaced all the necessary parts under warranty. I would advise everyone to check their cars for such defects and report any such defects to your local ford dealership, as if the defects are deemed a result of production they can be replaced. I'm one happy ford fusion 2010 owner! :shift:

Did you solve the noise problem?
