Thread: Different PUMA heat issue

Hi, mine was similar until I checked under the bonnet and noticed that the foam seal between the box and the duct had fallen out so the hot air from the engine was being sucked in. Once I fix it, it was all good, no more hot air.

Have not had this problem however every now and then the recycle/fresh air selector becomes jammed. Another problem I've had is that the passenger side receives much hotter air than the driver side with the heater on.

Had both investigated under warranty and apparently there was no fault. Would love to know how to fix both!

My recycle fressh air was jammed as it is a poor design, a cable has to be pushed to switch from open to recycle i think. Cables don't like being pushed and they bend and jam. I temporarily fixed with a cable tie, then had them replace under warranty. The problem is just behind the knob.

I had a fresh air 'snorkel' on top of the left hand guard to let the cooler fresh air in instead of taking it out of the engine bay. It seemed to make a bit of a difference.

Hi,
check the heater tap, rear of the engine up on the fire wall, passenger's side.
You can easily identify it by having some one move the control in the cab.
Is the cable moving the tap to the fully off position?

cheers

The foam seal is still in on mine but I can easily fit a handful of fingers between the foam of the fan box and the plastic of the intake duct. This gap lets lots of engine heat into the duct and is the cause for me of hot air coming in with the fresh. It's difficult to reach as the gap is underneath. I have tried to remove the duct so I can see if there's something to be done about it, but there's a fair bit of work involved in getting the duct out so I gave up. One day ...

Thanks for all the feedback. I had already checked heater tap with a friend who has a td5 but I'll check again and look at the duct/foam seal more closely

I have the same issue with my MY13 90 I agree it is hard to get at to fix, I wondered if from the inside via the air intake is the way to go

I've got the KBX Hi-Force intakes fitted and IMO it makes a massive difference. Even in Pilbara heat (40+ Deg) the fresh air flow has been significantly increased and the right hand one while mostly cosmetic does aid with some heat shift under the bonnet.

Unless there is a mechanical problem with the heater actually remaining "on" all the time. Back in the day had a 2003 Discovery that only varied between hot and very, very hot! That turned out to be a faulty climate control sensor (obviously not the problem here!).

Good luck with finding the problem!
