How to get A/C'ed Air to back seats?

-13 degrees :eek:
If it doesn't freeze his spots off, the evaporator/TX valve will soon freeze up !!
:D

Fridgys will correct me if I'm delusional.

That would be nice, but on my Rangie Classic (I am assuming early Disco is the same) the A/C fan is a different unit to the normal heater fan and it can only source air from the passengers footwell (and hope they don't have stinky feet!).

Crap pommy design, but until I can be bothered pulling the entire dash apart and custom building a decent A/C system it will have to do.

I've wondered the same as you, Byron... There's vent holes (at the rear of the centre console) in there but the aircon doesn't go that way, which is dumb.

I thought about taking it all apart and seeing what could be done, but......

just another job to do that hasn't been done....

Aircon to the rear is not standard, in a D1 93, from what I gather, so if you're feeling energetic, you could do some plumbing.

Good luck and report.

In my Owners Handbook it gives instruction for operating the separate REAR A/C SYSTEM....."where fitted" it says....own thermostat and fan speeds, probably coming from these vents.....shows controls on top of centre console to rear of mirror control.;)

mmmmmmm.......probably something to add to the "to do when got spare time" list!;)

Yeah I move it away from MAX after a few minutes running......it's SERIOUSLY cold!:twisted:

BTW....He DOES have spots!......a Dalmation!.....wouldn't want to freeze them off!:D

Please don't take this the wrong way, but that's mostly wrong.

Increased blood flow through legs, ears and tail is major way of losing heat. Panting excessively will often have the effect of making the dog hotter. Dogs lose most of their moisture, i.e. become dehydrated, by panting. Stopping them panting by cooling them down reduces dehydration. Cool air over head, ears, legs cools them down. If they are really distressed, a cold drink does wonders, if they won't drink (cos' they can't stop panting), then cold water over their legs and ears helps immensely. Wet towels work well, a spray bottle full of water can help too, sprayed over their head/legs.

Extending the air conditioning into the back for your dog is an awesome idea. Extra window tinting works well too. Opening the rear windows works for our dog.

there is that much feedback on this ,even some from our resident vet. you should have a solution.
Here is another suggestion, I tried it once in a falcon wagon( only because there rear vents were bigger) i was driving before we got rodeos.
sorry never got photos the end result will be a short l or a squared off s shape.
Get some pvc drainpipe , the rectangular stuff
bits you need are a straight length, and 2 90 deg sections
just make sure the holes on the 90 deg sections are the same size as the outlet at the rear of the console, or you could join two side by side,
remove the end directional deflectors,
attach as best you can,screw or duct tape
the riser only needs to be as high as the top of the console
on the top of the riser put the other 90 deg,
you may have to trim and modify for direction, or put a small piece of ofcut in the centre so it pushes out air on the sides

now the hard part, you get hot while rover gets cool, set the vent control for floor , and pump out the air.

I know it works on a falcon.

not wanting to create an ,I said he said banter, and unless your a vet,
i don't know where the increased bloodflow to legs came from, in my proffessional working life I have never heard that one, and I was involved with a lot of vets.
A dog's primary method of cooling is evaporative cooling from the respiratory tract through panting. When a dog pants it provides increased air flow over moist surfaces in the upper respiratory tract through rapid, shallow breathing. The increase in air flow causes an increase in evaporation from the upper respiratory tract. At the onset of panting, respiration rate increases rather suddenly from around 30-40 respirations per minute to around 300-400 respirations per minute. Under a moderate heat load a dog alternates between brief periods of panting at high frequencies and periods of normal slow respiration.

That is it in a nutshell.
My reference Dr Bill Porges ex UNNSW Vet School.
