Heating System Does Not Work

I am new to the CJ7 (86) and want to fix the heating system. From what I understand the heater core is under the dash behind the plastic enclosure. There are two hoses that I believe should be going through the coolant system but where do they hook up? When I bought it they were just poking out not connected to anything, so I figured they should tie into the coolant somewhere. Do you guys know where they should run to?

conner, if the 2 hoses that come thru the firewall from the heater core are unhooked there is a good chance the heater core is bad. If you look up blower motor upgrade in the search area of the forum, cj section it will give you all kinds of info on the heater box under the dash and how to replace the heater core. if you can afford it do the blower motor while your in there, it works really good. It's not that hard, but it does take a couple of day's to do it right.

Twink is absolutely correct, chances are the heater core is disconnected because it started leaking and the previous owner didn't feel like replacing it.

Connor, I noticed that you're in Santa Barbara. That's my home town. I left in 1959 when I joined the Navy and have only been back a few times for a visit. The last time was in 1979. We used to live up on the Mesa, and my dad owned a gas station up there. I graduated from SBCHS in '59. Whereabouts do you live in town?

I have been living out there for about 3 and a half years for college. I grew up in Indiana, I saw you were in Michigan (I actually just came back from Ludington today). I am next to UCSB in Isla Vista (Goleta) right now. I lived in the Mesa (on Oceano) a couple of years ago its a great area. Santa Barbara is an awesome place but it will be too expensive to live after college unfortunately!

Replacing the heater core is not that hard but it will take some time. Go for it.

Since I am working on all the wiring for the dash I might just go ahead and try to tackle this problem as well then I can route everything better and more organized.

if the heater core is leaking, can that be repaired? or does it need to be replaced?

I just checked prices you can get them for around 35 bucks at kragen.com so it might just be worthwhile to replace it.

I know what you mean. During my high school years, we lived in a small 850 sq.ft. house on Red Rose Way that my dad and uncle fixed up. They bought it for $5,000 around 1950. Last year, a friend of mine who still lives in SB send my a link to a local realtor ad that showed they were asking $730,000 for the house. Ridiculous!
