Hot air from vents
Gents

Since a while I“m getting warm air coming from the vents even when the heater temp knob is on full cold (blue). Seems the hot water circuit is not completely shut off. Does it sound like a PIA/front dash remomal? thanks in advance Thumbs Up Puma 110" SW

Yep mines the same, still very slightly warm. God bless the air con in the summer !!!
If I remember correctly there`s a hot water valve under the bonnet, have a look at him it may not turning off fully. Excuse the spelling I`am better with spanners and wires.

There is a known issue with 2.4 heaters in lhd vehicles, Land Rover have a fix which involves dash out and a mod to the internal matrix

If I remember correctly forum member dgardel has a copy of the land rover fix procedure

not sure how a mod to heater matrix could help , as the valve that stops hot water from getting to the heater matrix is under the bonnet

not sure if a lhd is different set up , but guessing it would be much the same just on the other side

Here is the heater fix as per Land Rover, but I doubt that it can help for the specific problem here. The heater fix solution is to solve the issue of warmer air blowing thru the vents at the UK driver side, than thru the left side (continental driver side) vents.

I'm very glad you posted this, I've just picked a new (to me) Defender up with exactly this problem. It's fine for now, but come summer it's not going to be.

The heater gets hotter as you turn it up, but I spent quite a long time with it on full cold today, where my Hyundai that I drove to pick it up I had to have at about 40% heat.

If the heaters hot or warm when the control is set to cold then it must be a valve problem or the cable that controls the valve

I was thinking to just fit a valve somewhere along the feeding line (Series type of solution) Puma 110" SW

Finally mine was repaired yesterday.
Were not the valve itself was one clip of the control wire that was broken.

Check that first after try to change the valve
