Hello again guys.On my 99 XK8 when the convertable top is up and closed and the front drivers window is open ,I get an annoying rattle from where seems like behind the speedo on the dash,yet when I close the window ,it goes away!!Any thoughts?.Ahh the joys of my Kitty.lol

 

Defroster duct? If so, try rolling in a few inches of 3/8 in vacuum line between the duct and windshield.

 

Hi Skid Mark,Im sorry I dont quite understand what you mean about the vacuum line and exactly where to put it,could you elaborate a little please?thanks for your help. Shaun

My defrost vents rattle - dropping by Ace Hardware today to see what they have.

 

If it's the defroster duct that's rattling, there's enough space between the duct and the windshield to roll a short length of vacuum line (small rubber hose) into the gap and stop the duct from rattling. Anywhere from 3/8 to 5/8 in size (depending on the size of the gap), it comes in black, so if you have other than the charcol interior you may want to dye it a matching color. If they're really loose, or you want a more uniform look, you can roll in a length as long as the duct.
