Windscreen condensation - sorted

[lrussell5]

Met a couple of very helpful TVR factory chappies at Goodwood friday. Having drooled over the Tuscan R (dont worry guys it aint as pretty as a Tamora) we got talking about those annoying little problems. They're still doing work on the seals but the condensation above the binnacle has an easy fix - point the right hand screen vent towards it ONLY JUST OPEN so that it produces a narrow jet of air. Worked for me in Friday's downpour. It has nothing to do with leaking screen seals so dont replace your windscreen!!

That's exactly what I've been doing to get rid of the moisture.
But where is it coming from and why is it only in one area (passanger side for me)?
Cheers..... Andrew

it's the general humidity in the cabin, forms just there due to the lack of air circulation in the tight gap, no other reason (according to TVR!).

Thats interesting. Mine went in a few days ago, and they rang the factory for advice,and the factory have told the dealers to take the screen out and re-seal it. The dealer said that there is a 95% chance of the screen cracking when removing it, so have ordered a new screen to be fitted.
I do also get the problem even with the roof off, when there is plenty of ventilation inside the cabin, and sometimes it is just a small amount of condensation, but other times, it is bad, a lot of water collects on the screen.The air vent dosen't seem to make any difference.

I guess they've changed their mind (?) They were pretty adamant with me that windscreen replacement was a huge unnecessary expense. Roof off makes no difference, the gap is so small you have to forcibly blow the air through in the right direction. Or maybe is is a new winscreen job in which case TVR will be well out-of-pocket wince all Tamoras are affected, hence their revised attitude ??

Nigel, just re-read your initial reply. I'd assumed your problem was in the same place as most of the others but if it's passenger side I guess it could be something more. Let me know if the windscreen replacement helps it, I might ring that TVR guy I spoke to Friday to see if he has anything useful to say

Mine doesn't do it. Or at least, I've never seen any condensation.

Like nubbin I have never experienced this problem and have driven in all conditions, including being stuck on the M25 for 2 hours in the rain. Clearly TVR know there is some kind of issue so why don't they make more of an effort to try to resolve it ? Frustrating

Lance,
Out of interest did you ask them why there is a larger gap between the screen pillar seal and the door on the drivers side. This one has got me completely puzzled as all Tamora's have it, yet the window frame and doors as far as I can tell are symmetrical. Any other hot fix tips from the TVR guys ?

PS. Goodwood was awesome !

Didnt ask them why the pillars were different but did mention how I fixed the gap (two aluminium brackets inside the bottom of the door need adjusting to alter the window carrier angle). As it's an easy fix he didnt seem too bothered. Talked about 18 vs 16 wheels with ref to the Evo article, they're as bemused as we are at the testers comments especially after the March article (also on 18s). No chassis mods planned (or admitted to). Exhaust resonant boom is apparently the unavoidable side-effect of getting the sound how they like it - fair enough!
No useful comment on the seatbelt jamming with roof down.
One interesting fact is the Tamora is the strongest/stiffest chassis they've made so far, by quite a way apparently. They spent quite a time refining the Tuscan one...

you'd know if it did. we're getting huge globules of the stuff just above the instrument binnacle!

[dicky]

forgot to mention, they're revamping the Tamora section of the factory website to give some beter pictures of a better looking car (18" etc) and more info. Not before time.....
