Rear heat mod for a JKU..

I searched here and even googled, but I came up empty.

Our JKU is our daily driver and the kids are always riding in the back. The only way for them to keep warm is for us to roast up front. Have any of you tried some kind of mod to pump some air back there. I am thinking maybe get some kind of duct off of a suv that will run in the floor and steal some air from the floor vents up front. I could get some flex vents and duct tape to the vents in the dash, but that would look real redneck. Anyone got any ideas???

Coats are cheaper.

This thread (http://www.wranglerforum.com/f33/hea...ats-73736.html) suggests heated rear seats as well as the possibility of a independent rear heater.

Terminator - wish I had an answer for you. I'm surprised I can type considering that I'm still rolling on the floor from jcossey's comment.

That said, my kids are always hot...course its only in the 40s and 50s up here right now. I run the heater...warm em up...then crack the window so I can breathe!

12 Volt Rubberized Heater with Fan

In a past life, I had an FJ55 LWB Toyota Land Bruiser which had a rear heater on the floor behind the center console. It included a fan which was switched on at the dash, and the heater pipes ran from the engine to heat it up.
It worked really well, but I rarely, if ever, sat in the back seat.. It would be a simple install if you could ever find a good one as this was about 30 years ago.

Go to Amazon and type in 12V heater. I say there because not only do they have several choices but you can read customer reviews on them. Many of these are crap and break real easy so only buy one with excellent reviews

A couple of heavy blankets would be easier. I have one in the back of my TJ with a couple of pillows... My kids love it.

Coats and a blanket have always worked well (although I may upgrade them to a Snuggie to avoid the "he/she has more blanket than me" arguments). I don't think I've ever heard my kids say they were cold back there even though we are in the low twenty's most of the winter.

Fleece throws are wonderful to keep stashed under the back seat for the kids.... I always have a couple back there. They don't take up much room, and are a God send on topless evenings when it turns cool, and the kids start turning blue...

I know. When I first got the TJ, the temp was in the 80's so we decided to take a ride down through the bottoms. WE had the top off and were having fun. The sun went down and the temp dropped 20 degrees. All we had on were shorts and a tee. The last 10 miles home I think I drove 10 mph to keep from freezing. Learned right then, throws and sweatshirts are a must to keep in the Jeep

I bought some 12v heated blankets to keep the wifey and kids from stealing my sweatshirt to cover up their legs with. The only thing I had to do was add a 12v outlet to the passenger side and one to the back. They love them.

Supposedly it's not a good idea to put kids under electric blankets and such. Something about elctromagnetic fields.

I would think it would be fairly straightforward to find something a little narrower than the flexi ducts used on clothes dryers and find a way to clip it to a front vent and then they can have the other end in the back with them.

Electromagnetic fields only come from things using alternating current (AC)). Not generated by direct current (DC). In a former job, I worked in an electromagnetic effects lab for NASA.

Me, personally? I carry 2 airplane blankets wrapped to the roll bars in the back. The girls use them as required.

Ok. So not electromagnetic then. Regardless, heating pads and electric blankets come with warnings to not let kids use them.

My freedom top leaks like a sieve anyway. Probably not a good spot for electric blankets.

I like the blanket idea, This one from JCW has a timer on it. That would come in handy if someone forgot to turn it off.

I did a research project for a class while in college for emergency adminstration and management. I was studying the different causes for home fires and after some extensive research of office of emergency management records across the united states, i found that the #2 cause for homefires was electric blankets. The #1 cause was hair straightners.....take my advice and leave the elec blankies outta the jeeps.

I've never been to a single structure fire that was caused by an electric blanket. I'm not saying it can't happen, but if you buy a quality blanket or throw and keep it in good working order (watch for damaged cords, coils, etc.) I think you are safe. Don't let sections of it get pinched, avoid excessive wear in repeated locations and don't put anything on top of the blanket when it is turned on. Follow the manufacturer's directions and make sure the 12v plug has a fuse in it.
