Non-A/C Climate Control

Hi guys,

So I've moved from a TD5 to a Non-A/C 2.4 Tdci and I was messing about with the climate controls yesterday right before I drove back into the workshop. To my surprise the lower slider (highlighted) wouldn't budge from what I remember was the far right position.

My question is, is it broken? I'm gonna hazard a guess and say yes, although I never had a chance to ask the mechanics.

Also, what differences is there between the A/C and non-A/C spec'd pumas? As far as I'm aware there's no difference with the number of vents?

Cheers

Stuart

Yes, it's broken, unfortunately. All that lever does is change from incoming fresh air to recirculating and isn't related to the A/C operation.

There are no physical differences in the cab between A/C and non-A/C models except for the button to turn A/C on. Externally, you'll have the flat fronted radiator grill instead of the protruding A/C one. Darren

The only difference between a/c and non-a/c is that there is an additional heat exchanger built into the heater box in the dash on the a/c models, together with the refrigerant system etc needed to support it. The air passages and control flaps are exactly the same.

As noted above, if the slider is stuck it is probably an indication that the slider control unit has broken, which is a shame as it is absurdly expensive. The flap that it operates is above the passengers feet, so it might be worth checking that there isn't something physically stuck ion the mechanism before starting the dismantling process.

The heater controls on the Puma sadly do not exude quality and are rather prone to breakage.

Thank you both for answering that and the questions that I was going to follow up with.

Will be upgrading it down the line with A/C so good to know, cheers!

At £160 I'm certain I will be able to fix it! Stuart

Yes, it is an absurd price for a rather crappy plastic jobbie!

Just remember that with a/c you have yet more things to go wrong.

Mine was stuck for a long time but I kept fiddling with it and finally it came loose. I never really understood why you would want recycled air over fresh air ? Is it something to do with manure ?

I use it as a means to close off the intake, which otherwise seems to let a constant low level draft through. Can also help with warming up on a cold morning but not for too long as moisture tends to build up too. Darren

Had something similar with mine,

luckily it had just got jammed? there's a cable like what I would describe a Mtb shift cable that comes out passenger side bulkhead under the bonnet, it looked like it'd been over rotated I manually pushed it back and it's worked ever since (2 years +)

We had that problem on our 2010 Tdci, luckily JLR's warranty fitted a new heater unit! This was back in 2013, though!
