Rear A/C
 

I have recently happened upon an idea to find a place to splice into the a/c duct in the dash and run a small duct through the center console to the rear seat. Often, my two year old daughter rides back there and it takes too long for the back to cool down. Has anyone else thought of this or have any ideas of where a good place to tap into the a/c would be?

I wouldn't think it would be too effective. The extra duct work would reduce the overall efficiency and airflow.

What I have done in the past in this situation is to set the temperature at its lowest fan at max and push the DEF button.

This sends the air up the windshield towards the roof and back. The same with the side window defrosters. Once it car is cooled, adjust as needed.

The RECIRC button also helps the keep the cool air in the car.


I giant Slurpee couldn't hurt in the meantime. :)

Two-year-old + Giant Slurpee = Massive mess in the back seat:(

Maybe some flavored ice water in a Tommee Tippee cup? :rolleyes:

you could always use something like this

all you have to do is run a low and high side line to it from your existing lines, that's how newer cars run their rear ac, and how they did it all the way back to the 50s. any competent ac shop should be able to tie into your existing lines and run new ones to the trunk, you could mount this on the rear deck or below it with some venting going up.

This is an issue that came up after our twin grandkids were riding around in the back of our wagon, and we felt so bad that they were drenching wet every time we pulled them out of their child safety seats. Hence, we bought a Caddy with rear vents/fans etc. Has anyone ever seen/envisioned/built a safety seat with built in fans/perforated upholstery, and maybe even a hose hook-up to a coolbox like they use in NASCAR to keep the driver's heads as cool as possible? With the miniaturization of so many components making such a thing possible, how many parents/grandparents would be willing to spring the $$ for such a thing for their precious cargo? Any inventors out there? :lol:

a couple of my customers have recaro baby seats. they look just like a really nice racing style seat, with nice perforated mesh material to keep them cool. odd though that the only people who have them have cars with rear ac and dvd anyway.

You might need to have the amount of refrigerant charge adjusted as well to compensate for the larger system. It won't be much, probably no more than half a pound of juice, but something to account for nevertheless.

If you are anywhere that salt/snow or corrosion are a problem, i.e. the Rust Belt, I would suggest using rubber lines and leave as little metal running outside the vehicle that you possibly can. Run them inside if you can get away with it.

Your best bet will probably be to crack your sunroof and/or back windows for a few minutes to vent out the hot air, then close them once the air starts blowing nice and cold.

I will also point out that setting the fan to maximum is actually WARMER than somewhere in the middle. The air passes through the evaporator too fast and doesn't have time to cool enough. This is true of pretty much all A/C systems.

I have a fair amount of experience servicing A/C on all kinds of things, so this is just from my experience. YMMV.
