Window whistle

Recommended Posts

Hi all

My Cayman is suffering from another common issue I believe - wind noise eminating from the passenger window above 40mph. I've done some googling and it seems most people think it comes from the either the wing mirror or the window seal. Going to have a look at this at the weekend and just wondered if anyone else had experienced it and/or had any advice?

Cheers

I had this on two cars before - one was caused by the wing mirror cover being slightly loose.  Air would get under the cover and make a horrible whistling sound.  Solution was remove and refit the cover properly.

 

On another vehicle I owned (MX-5), I would get a noise above 65.  This was caused by the window not being tight enough against the seal around the roof.  Solution was to remove the door card and adjust the tilt mechanism to push the window in toward the seal.

 

I would visually compare both sides and see if there are any obvious differences.  That should point you in the right direction.  It should be pretty clear if something is out of place.

Thanks Aaron. Yes another suggestion on a different forum was to tape up the gaps in the mirrors, seals, etc and go for a drive. Then remove bits of the tape until you discover where the noise comes from. Sounds like it could be worth a whirl!

Just thought I'd raise this one again as my passenger window is still whistling!  More noticeable in the winter I suppose when you have the windows up more often :) 

Tried using tape to determine the source but found that to be inconclusive. 

I read on another forum that it could be due to the glass not sitting tight enough up against the rubber seal, and that there is some sort of adjuster at the bottom edge of the door under a rubber grommet - anyone ever come across this before?!

Think I have heard of some adjusters at the bottom of the door where you can adjust the amount of tilt the glass has.

Yeah I think it might be something I have a search for when I have a spare moment in the daylight!

There are "adjusters" on the bottom of the door... When replacing a window winder mechanism for instance, you use them to adjust the glass run etc... Common issue is that people shut the door by pushing on the upper portion of the door glass hence affecting how the glass seats on the rubber surround 😉

I have something similar on the driver's side of my Cayman; a whistle at higher speed. 

 

More detail on those window adjuster wotsits would be much appreciated. (And yes, I am an idle hound and can't be bothered to Google it for myself!)
