Thread: Hot air in drivers footwell

In my high tech defender the actuating bowden cables sometimes do not fully close the flap in the heater box. A short push at the start of the warmer weather closes it until next winter. The lever is on the top of the heater box.

Some machine or engine oil down the actuating cable helps but never seems to fully close the flap.

My V8 county get extremely hot on the floor due to the exhaust passing close to the thin floor panels, I also find hot air on the back of my leg during summer from the hand brake hole.

Thanks for the suggestions dromader driver and tam242. Will give them a try in the morning, take it for a spin and report back.

Alright, update time....
Had a play with the actuator bowden cables before going for a drive. Tried to push them as far as I could.
Unfortunately, no luck, air still blowing out at my shins.

As I was driving, I thought I would try a few different things....

1. Temperature set to cool, fan direction set to the top, fan on 0:
Warm air blowing out the bottom vent, none at top. As engine revs and load on the engine increased, the force at which air was being blown out increased.

2. Temperature set to warm, fan direction set to top, fan on 0:
Hotter air blowing out the bottom vent, none at top. Same occured again, as engine revs and load increased, the force of the air increased just now hotter.

3. Temperature set to warm, fan direction set to bottom, fan on 2:
Hot air blowing out the bottom vent. Still evident but not quite so much was that the force of the air increased as engine revs increased.

I did the same test as number 3, except I set the temperature to cool and it made the air blowing out slightly cooler.

Any more ideas.....

Very grateful for the previous suggestions and am open to any more.
Am off to use the search button to see what I can find

My 110 just blows hot air through the firewall from the transmission tunnel next to the clutch. That wouldn't be the problem you have would it?

It is a bit of an effort but this works extremely well, it has made a huge difference. We travel up to the Northern Territory every year, in relatively comfort since insulating. The main area to insulate is around the tunnel and across the seat box base.

Thanks for both of your responses guys.
Not quite Mark, the air is coming out the same place where the heater and cooler normally blows through. The difference is that the air is always blowing through and is varying with engine speed which leads me to believe that it is something more to do with the heater itself and a gate inside not shutting.

Bundalene, thanks for the links, I remember looking at your defender build up and being amazed by the attention to detail and a really schmick final product-well done! I also liked the 130 build up too. The insulation is certainly on the list of things to do for both 90s. Thankfully, this one isn't a daily driver so we can afford to pull it to pieces and have a play round with it.

Might be pulling the heater apart me thinks...
Any more suggestions are welcome
Thanks again
