Wind noise

[kbj149]

Stop sniggering at the back :-D

On a recent trip from Cardiff to Warwick, its maiden long motorway voyage (lets not even talk about how much it cost in fuel) the wind noise inside the cabin was terrible. The majority of the whooshing is emanating from the top of the window, very top left of the seal as you look from the drivers seat at the point. Very noisy and almost impossible to keep warm - I've identified a couple of potential causes:

1 Noticeable gap where the rear panel folds back, the velcro has come away and there is a fairly wide gap
2 0.3" gap at the top of the window where it meets the roof when the glass is fully up
3 The rubber seal around the targa top could do with replacing as its got very soft and looks to be perished in places

Now, I can resolve the above my replacing the seals and velcro, but I fear the issue is that the both doors have dropped by just over 0.5" - I think that even if I replace the rubber seals and velcro I'm still going to have an amount of wind noise.

To compound all this, I put the roof back yesterday, when cold, and I've cracked and split the rear plastic window. So, I think it's time for a new roof anyway. My fear is, I invest in that which sorts out the above points but I've still this door dropped issue and it'll still be noisy in the cabin, is that an expensive fix? Not least, in the wet, its getting, er, wet.

Cheers in advance.

Kev.

Are you certain the doors have dropped, the window height is adjustable so if the doors have not dropped then you may be able to close the gap on the window, there is an adjusting screw behind the brush strip at the bottom of the window about third of the way back.

I agree with myph. It's known that the doors can sag, but I'd be surprised if they had both sagged, and by the same amount of ~0.5". I've never had to mess with the door alignment but I understand it can be tricky.

With regards to the window/roof gap, the thread link here might be of some use. As mentioned there is a hidden glass height adjustment screw just below where the glass/door line which might close the gap. Alternatively I found that the roof panel seal runners are sometimes packed out with washers to close asymmetic gaps between the glass and roof.

If you are going to have a complete new roof done you might as well wait and see how this turns out before trying to re-align doors etc., as issues with gaps might be resolved during the re-roofing process.

When I was training, (some years ago) £10.00 wages bought you about 28 gallons of fuel.

My trainee son earns about £230.00, he can buy approx. 38 gallons.

Relax, you're actually better off but you don't know it .
