VENTILATION PROBS

[WARRENINOXFORD]

Hi All,

After bumping into a chimera driver in B&Q car park in oxford a few weeks ago he told me that if i have any problems with my car (cerbera speed six) rather than spend ridiculous amounts of money at a tvr dealer speak to you lot and hopefully i can sort the problem out myself. So whats happening is at speeds above 60-70 mph there is a cold draft coming in around the drivers footwell, even with the heating turned up at this time of year it still remains very cold can anyone advise me, i have had a look around and it seems as though it is only gaffer tape that holds the ventilation pipes (hot and cold) to the eye ball vents.
i think it is just bad fitting that lets by the cold air. am i right or not????????

many thanks

Hi There

I seem to recall that there is a vent that points downwards into the footwell (on mine anyway) Is it closed?

Also on the transmission tunnel there is a vent which lets a good amount of hot air into the footwell as well which may help

When I first got the beast I did not appreciate that you have to push the hot/cold controls to turn them on and off - May be worth checking whether the cold one is on?

Yes there is a footwell vent below the dash, this needs opening up otherwise no hot (or cold air) There, it sounds in your case that this vent may be open but is only blowing out cold air. There are numerous holes in the bulkhead as well which if not sealed properly let in not only water but air. Don't forget the heater won't work until the engines warm, and also fiddle with your heater controls to ensure it is blowing hot air and not cold, although the knobs look good they are not very user friendly in terms of off and on. Lastly if all else fails it might be the heater matrix.
Sorry to point out the blindingly obvious if you've already checked.

warren, you should have a hot and cold air inlet down there. The cold is the one you can reach whilst seated properly in the car, the hot you can only reach if your 2ft neagative 1!!! ANyway too get maximum heatage down at the toatsies make sure the windscreen vents are closed. Also make sure the hot air pipe is connected to the outlet(sometime becomes dislodged!).

Should be problem solved! Otherwise 2 pairs of yir grans best warmers should do the trick!!!

Over and out.

Do you mean the two big ones in the middle of the dash above the stereo or is there a way of closing all the little demister ones along the edge of the windscreen.

I think you can buy plugs for the little demisting vents. I think they are about £12. Good for the summer, as the car can get hot, even with the aircon on. However, you need some air on the screen to stop it misting up in winter.

Glad I'm not the only one! At 70 mph+ its boiling hot in the summer, even with the air con on, and freezing cold in the winter, even with heating on full and all the cold air vents closed. It was so bad in the recent cold snap that I was driving up North with my fingers frozen like meat hooks, clawing at the wheel.

I was wondering whether there is a panel missing under the steering wheel, but I suspect its just a design 'feature' which allows drafts to blow in at speed and that I'll have to live with it, though the idea of checking for daylight armed with Elephant tape is definitely one to try.

Having looked at the similar topic from last November that Kojak referred to I noticed that someone else has had the problem of fumes - I had a really bad dose which got worse if I opened the windows. Discovered it was the petrol cap that was loose - you could lift the whole unit out and peer down in to gallons of petrol swilling about in the tank. When I opened the windows it sucked the fumes through into the cabin. Its all gone now I've had it resealed, but I'm still partial to sniffing the odd bucket of petrol.

I had the same problem and had passengers complaining so i bloked off the route through the front wing on the passenger side by filling a plastic bag with expanding foam inside the wing getting access under wheel arch. then in the winter i push two soft balls which i got from Toys R us and push them in the two holes near the indicator lights, problem solved

Thats the ones Andy. It's not actually enough to heat your feet up, just stops them freezing!!
