Thanks all.

I'm basically just trying to find the source of a whistling noise that occurs when I pick up speed. I'm sure it's due to a piece of trim and there does seem to be a small gap between the wing mirror and door panel.

Hi All,

Well I've finally found the cause of the whistling. See below.

I went for a drive today with a roll of tape in hand and used it on various bits of trim while I was out and about. The whistling stopped when I put some tape over the area marked in the image.

The thing is the passenger side mirror has this gap as it's where the mirror is hinged, but there is no whistling on that side. The only thing I have noticed is that the gap on the drivers side mirror is slightly wider than it is on the passenger side. Makes me wonder if something happened to the mirror prior to me owning the car.

The only issue I have now is how to remedy the problem. If it was a fixed piece of trim I could easily fill in the gap, but as this part of the hinge that isn't going to work.

Hi All,

I have a further update to report which I think positively answers the question about the whistling noise.

Was having a look at the drivers side and passenger side mirrors today and discovered something which makes me believe I've found the source of the problem. See the images below.

Passenger Side:

Drivers Side:

With the drivers side mirror open I was able to see daylight between the bottom of the mirror cover and the support. When I do the same with the Passenger side mirror the rubber gasket is sealing the gap so I can't anything. The question is, is it possible to get hold of the rubber gasket and is it an easy job to install?

Great result! I would imagine the grommet comes pre-fitted to the mirror assembly, which probably makes it unlikely to find separately. Could you live with a bit of "black and nasty" long term, or perhaps cut a bit of black foam to fill the hole?
I have a ford dealership located just up the road. I know them pretty well and was thinking of popping up to see them in the week. They might be able to help me out.

For now I'm just happy to have found the source of the problem. I'm sure a solution can be found.

Well I visited my local Ford Dealership today.

To start with they confirmed my suspicions, the drivers side mirror is indeed aftermarket.

After speaking to the parts department they have sourced me a genuine Ford unit at a very reasonable price and will fit it for me on Wednesday.
