Thread: heat comming from vents

Hi,
I have noticed the same thing happens in my 2001 TD5 Discovery.

I thought I was imagining it. As the cabin would get warm without anything switched on.

I usually just turn the aircon/fan on.

Would be nice to know what causes it thought.

cheers

I occasionally have warm air venting through the foot well when aircon set to all vents only seems to come through the bottom vents, if I turn aircon on then off it sometimes stops it.

Yeah i have the same and can not work it out ,i also turn the air con on for a moment then turn it off and it stops sometimes

if you have the a/c set to econ then only hot air comes out no matter what.

if you just want to have fresh air coming in then set to econ & turn the fan off. this is the only mode that the fan actually turns off.

Hi guys
I spent ages trying to figure out what this was! It actually cooks my left leg...and then someone told me the most likely cause...

(drum roll)

Blend motors.
Now it might not be true in all your cases, but likely. If you look on RAVE there's about 4 (or 5) different little flaps with motors for mixing & distributing air from the HVAC system, and it's not reasonably common for them to fail.

So while on a hot day, depending on what's failed and in which position, your aircon is sending nice cool in in one direction one of the little buggers is sending hot air elswhere. A side effect of mine is with the system off I get little or no 'flow through' vents of ambient air.

I think the motors come as a set (I'm looking at doing mine in the near future) but apparently the job requires quite a bit of disassembly of the dash etc as you'd imagine.

Link below is for a P38 but may be the same as D2:

It's quite a relief/revelation to get into my gf's V8 where the HVAC works properly.

ffs ill cope with the warm air than pay that ....jjjjjsssss...lol

cheers

On older D2's air comes in unless the recirculate button (looks like a recycle symbol) is pushed in - even if the fan is off. Later D2's as below you need to set to econ & turn fan off.

thank you to all , now she will be happy
