CJ7 Heater Box Removal and Repair

- I receive many requests for CJ7 work/repair videos. Unfortunately I didn’t record much of the work I did in the past - and fortunately I don’t have any pending work/repairs.
That being said, here is a video that I did last winter on how to remove and restore the function of a CJ7 heater/blower box. It is not as detailed as I would have liked it to be (the reason I didn’t post it earlier) but it does show you where all of the removal nuts are to be found and some of the difficulties in removing it. If you are needing to replace a heater core you would follow these same guidelines.
In a nutshell - you need to remove the four screws holding the top of box, the four nuts on the firewall, disconnect the two coolant lines from the heater core, disconnect the power feed wire at the blower, and under the dash remove the control cable to the box and remove the defrost duct from the top of the box.
The blower box is not difficult to remove BUT requires a bit of patience and finesse - and an extra set of hands can go a long way in helping with the reinstall. Not necessary but helpful. - Jak na to + styl
Getting ready this morning to change out the heater core on my 1985 CJ7. This is helpful thanks.
Good luck!
Great job brother! I’ve been scratchin my head trying to get to the heater core on mine and you really helped me out lol. Thanks a bunch for posting it! 🙂👍👏👏👏
Glad it helped.
mind if I ask what air cleaner set up you have? the video was great, helped me with my heater core and fan motor replacement. Thanks
I modified an air cleaner from an early 90s Cadillac - czcams.com/video/_kjddzI70CM/video.htmlsi=xlMrZd-xE7N8LLNF
Do you need to take your dash off to get to this?
Nope.
I noticed the cable bracket is moving, is that supposed to move?
Patric Bear nope. The main bracket is simply riveted to the box and was “giving” because the cable was frozen up. Working properly it will move slightly but all of the real movement should be done by the attached hinged bracket the operates the heater door.
@@TigerCreekFarm thank you for your reply, I commented to soon i know lol after watching till the end I saw it working like I thought it should. Keep up the great work, 🇺🇸👍🇺🇸👍
To reinstall, did you put the air box in first or the heater box?
