So I bought a ford X with no rear A/C. I love the X but it does get pretty warm in the back during the summer. I believe it was a fleet vehicle as it has a bench in the front. Any ideas on how to cool it down back there? Also have the same prob in the winter but I am going to order a Maradyne heater for that.

 

So no vents back there? There is no additional AC in the EX just the one unit that cools the entire truck.

 

None of this is behind the rear jack door? See pic in thread.

I think he means there is one compressor for AC. I guess in theory you could add it, but I can't imagine how hard that would be. Source the lines to take the heat and AC to the rear, source the ducts and fan motor, source the connection point from the front radiator lines to the rear (if memory serves there is a valve of some sort that is piped in)...wiring...that's a pretty big job. I'm sure it can be done, but you'd want to get on the Ford Parts web site and try to figure out all of the components needed, then start scouring yards for the parts...big job.

 

It'd be cheaper to pull the headliner and side panels in the rear and add the sound-deadening/heat insulation "pads" than trying to ADD the rear A/C and heat components (just my opinion based on parts availability and the work involved).
Either way, the headliner has to come out (to install the ducts - IF you source all the components - perhaps a wrecked/high mileage donor Excursion is cheaper, a couple of thousand dollars will likely get you all the parts with a vehicle you can resell again later to get most of you up-front cost back)

There is NOTHING above the headliner - so in the summer sun really heats up the interior, same issue in winter with it cooling off the interior. You SHOULD have the privacy tinted windows (2nd row back - should be very dark) and do a good job of helping keep the sunlight out in summer. Put a piece above the overhead information display (if you have that?) because the summer heat causes the resistors to de-solder themselves (and I have to every 2-3 years "fix" that too.

 

There is an Excursion in the Mine that has all these rear AC/heating parts in it still. Vents, ducts, A/C parts, controls...

I might go back this Friday and verify. I see the OP is in Oregon, so might not be workable due to distance/shipping.

 

There are no lines in the rear housing and no rear a/c controls. I am not interested in trying to run new lines and vents just wondering if anybody had some creative ideas on keeping it cooler back there. I think the mardyne heater will work well in the winter. That's a pretty easy install.

hope that link works. The a/c and an inverter and you are good. It even has a remote so you can control it from the front! Strap it down and the back and run the exhaust out somewhere.

 

I was thinking a roof AC like an RV has. Lol. No seriously, about all you can do to help aside from installing a rear AC unit is super dark UV tint on all rear windows and pulling the headliner and adding insulation. I went through this with a 2004 explorer we bought and ended up selling it to get something with rear air. There are a ton of cheap Excursions you could combine with yours then sell the rest.

 

Old thread, I know, but I wanted to revisit this as I just disassembled the Excursion I had mentioned and figured a few things out in regards to retro-fitting an Excursion without factory air in the rear.

It is easier than I thought to remove or install this rear A/C system. You have to get the harness from the roof of the donor truck. You need the controls both front and rear in the overhead. You will need the mounting plate that is hidden under the headliner for the rear A/C controls (it is just an extended plate for the front overhead console). The A/C ducting is built into the headliner. I don't know if the trucks without A/C in the rear have the same headliner or not, but if they do, this is a very easy conversion. If they don't, then that is a big challenge, as shipping a headliner would be near impossible. You have to get the freon and heater lines that run from the drier under the hood (passenger side by blower motor) all the way to the rear. They are really not that hard to remove. By the drier, there is a Y junction on the trucks with rear A/C, so you would need to go all the way back up to that and get it with the rear A/C lines...easy peasy getting that piece. The ducting from the blower in the rear to the headliner are quite short and easy to remove/install. The plastic trim that covers the whole A/C assembly in the rear is super easy to remove as well. You would also need the 5 circle vents for the headliner. There are no floor vents from the rear heat blower. Only the ones that run from the front blower. Would also need to put fuses in the right spots for the rear A/C components as needed. I haven't dove into that yet in the wiring diagrams.

Overall, if you had the donor vehicle nearby, this is an easy retro-fit in my opinion.
