Jeep CJ7 Heater Box Restoration | Project Rowdy Ep028

[@michaeldowney8429]

I absolutely love your attention to detail, Mike ! I think you missed your true calling in life. Automobile restoration just seems to come so naturally to you. I also like the fact that you just don’t condemn everything. You actually take the time and energy to fix this up yourself. Kudos for perhaps the best auto restoration series I’ve seen online.

[@UCanDoIt2Mike]

Michael Downey Hey Michael, I absolutely love this comment. It truly is a blast to work on these projects. I am learning so much on how these things work. Really enjoying this project and the great people like you that I get to interact with. Thanks!!!!! Mike

[@tombloch208]

Thank you so much Mike. I was watching the video for a few times, gathered all the required material for a period of 2 years, right here in Germany. The designated period for getting the work done was last July, but then I got hit by Covid. Now I am returning from 4 days in front of my garage with my '85 CJ7 Laredo. Heater core replaced, blower motor upgrade, everything work well and it turned out very successful. Couldn't have done it without you and your great videos! Thanksaton!

[@UCanDoIt2Mike]

Absolutely Love It! Glad you were able to get yours all restored and upgraded. It should now last you a very long time. The extra heat output with that new blower motor is well worth the effort. Enjoy and many thanks for your feedback. Love hearing when these things work out for others! Mike

This is one of the the best things I did for making mine a decent daily. Where I lived at the time was way out in some canyons 20 minutes of bad roads to get to a highway. The next was Ford internet wiper switch / module. Super easy, my next would be to run foreward off-road lights on a switch/ relay system so I enabled them with the regular switch, but they would only come on with high beams, and turn off with low beams. Also ran rear floods similarly, they came on when in reverse with high beams (no switch) or on with a switch.

I'm about to rip the heater box out of my 80 CJ-7 and I'm thrilled to find this video. Thanks for being so thorough and providing all the info you did. I'm going to make a video because I'm do some 3D printing for mine, but I'll be sure to point my viewers to your channel. Thanks!

[@UCanDoIt2Mike]

Relatively a simple process. You will learn alot about how it works when you take it apart. Cool stuff. Thanks Mike

[@briangaffney422]

I like the attention to detail. I'm getting ready to fix a lot of problems on my 1980 CJ5. It's a fiberglas tub & I'm the 4th owner. I will use your video & PDF files when I pull out my heater box. The prior owners really didn't know what they were doing. I have restored the complete suspention system as wel as the fuel,brake & clutch systems. Keep up the great work & thanks for taking the time for such things as the template (above and beyond).

[@UCanDoIt2Mike]

Sounds like you have already corrected or updated many things on your CJ5. Hope you continue to find success in your updates. In the end, it will be very rewarding. Thanks for the kind words. Mike.

[@willbar1961]

Man going back and reviewing this stuff after not working on my jeep for a long time brings it all back. I was thinking that blower motor was the same as either the Chevy Vega or non-A/C late 70's Chevy trucks. I had both in the past but memory is a little fuzzy now. I've had problems with replacement heater core not being a drop in fit too. Having the hood, dash and windshield off sure helps! This is excellent work and I will probably refer back when I start on mine again.

[@UCanDoIt2Mike]

Several simple repairs and upgrades that should make these heater boxes work better for us. Cheers and have fun tackling yours! Mike

[@bjack8645]

You sir are meticulous and thorough, fun to watch. Thanks for taking the time for such things as the template (above and beyond) I appenticed back in the mid to late 70s and did a lot of this type of work. I enjoyed these days of simplicity, long live my YJ. Thanks

[@slyhog007]

Wow, this is giving me some serious PTSD from when I restored my 1990 YJ heater box and cables, which is very similar to the CJ box. You're gonna love the bigger blower motor. I replaced my heater core and weak blower motor (both original) in the dead of winter and man the new motor moved some serious air. I'd have to either vent in some cold air or turn the blower completely off to keep from burning up in single digit weather! Love the build my friend.

[@UCanDoIt2Mike]

Yea... I think the problem now is how not to burn my feet! Cheers ... Mike!

[@TysonNeil]

After my 82's heater unit has been disassembled and stored, I'm going to finally tackle it and this is a very good refresher on heater units. I hope to send my chassis off to powder coating soon. Then get on to putting the whole jeep together. Not many people get into the details of heaters. I'm glad you did.

Thanks for posting. You did a masterful job on the restoration. I am restoring a CJ8 and a J10 pickup. I will definitely be referring to this video. I haven't taken my heater box apart yet. I bought the CJ8 off a woman about 10 years ago and it has been garage kept since then. The tub and chassis is stored in a metal building and the hood, fenders and fiberglass 1/2 top are stored in the loft of my 30 x 36 workshop. I have a rebuilt 258 to go into the CJ8. The J10 also has a 258. I am slowly accumulating what I need to do the restorations.

I just wanted to say thank you for the videos and everything extra you have done. you explain things simply and are easy to understand. I am going to restore my 85 cj, I hope next year, I hope to start taking it apart in the next few weeks, I have watched a bunch of your videos, even the ones that I don't think I will be doing. I hope to take things apart myself and then shop out what needs to be done. going back as stock as I can. but want to clean it all up stop any rust and make the Jeep an everyday driver. going to do my heater box myself and add aftermarket AC. not sure if I will do the heat/AC one or just AC ( probably just AC) anyway only proper to say thank you very much, I know this is a few years old but what is great about this is someone can find it years later and it still helps

[@UCanDoIt2Mike]

I bet it would be hard to find originals and those that have heater boxes for sell, probably would not just part with the springs. My local Ace Hardware has an incredible assortment of springs that I bet you could find one that solves your issues. Hope that helps... Mike

[@DrHughWegwerth]

This is an incredible video….. thank you. I need to do this. Nice job on the editing. How hard it it to take the dash off to get to the heater? Do you have a video on that?

[@UCanDoIt2Mike]

Glad you enjoyed the video. I do not believe that you have to remove the dash to remove the 2 units. It may help to remove the passenger seat just to give you more room. From the engine side of the firewall, you can detach the hoses, 4 nuts, drains, and Blower Motor wire. The video shows where the 3 control (push/pull) cables are attached under the dash. You should be able to reach under there and detach as well as the flexible vent connection (between the Heat box and Fresh Air Box. The heater box should them be available to remove. For the Fresh Air box, you will also need to remove the inlet grate (where the fresh air comes in) from the top of the cowl. I would at least give that a try. Mike

[@DrHughWegwerth]

@@UCanDoIt2Mike Thank you for the quick response.

[@UCanDoIt2Mike]

To answer your other question.... How hard is it to remove the dash?" In reference to removing the Heater units... The dash could be un-screwed from the tub and pulled back a little. The Speedo cable will restrict how far you can pull it away. I will reiterate that you should not have to do this for the Heater refresh. Here is a video on me taking out my dash. I did it as a part of a total restoration. kzbin.info/www/bejne/pWfQiGhrfL-gf8k

Thank you so much man. I daily drive my cj7 and about a week ago i hopped in it and now that its getting cold here in Wisconsin the windshield started fogging up. So i took my spare wiper blade that i tuck by my vin plate and used that as defrost. So my stupid gen z ass didnt see the moter sticking through the fire wall so i figure the moter is in the cab. So i look under the dash and assume the thermo resistor thingy is the fan so i pull the plug. Sure enough no power. I pull the switch and its coroded so i take apart the switch clean things up and test ot with a ohm meter and it works but then the pcb the prongs are mounted on falls apart and the spring pops out. So i bought a new one drove a week without heat oe defrost (not that the old jeeps have a good defrost anyway) plop the new one in to find out it still doesnt work. I pull and test the new switch incase its bad (how good could rugged ridge possibly be) its working. But thanks to your vid i now know tucked away under the battery tray is a blower. It was working so my theory is when i had the engine out this summer the harness drooping unplugged it half way then driving it vibrated the connector off then when i go to use it months later the blower isn't getting voltage. So this whole time i could have had heat but im just stupid apparently. But in the mean time i got by by having no front carpets as a v8 and headers warm the floor nicely 👍

Thanks for the video, really helped. My only question is about the blower motor replacement. The one that I ended up installing has a 2” hole on the side of the motor that sticks through the firewall. I’m guessing it’s for ventilation but it is also exposes the inside of the electric motor to water, dust, and grime. Did the motor you used have this opening and if so what did you decide to do about it? Thanks!

[@UCanDoIt2Mike]

Mine has about a 1 inch hole in the side of the motor housing that protrudes through the firewall into the engine bay as well. My kit came with a PLUG that I plan to cover that hole. If your Motor did not come with a plastic plug, I suggest finding one at your local hardware store or online. Cheers! Mike

New subscriber. Awesome video. I will be using your instructions and gaskets plans to do this soon! I know you have not hooked it all up yet, but does anything need to be done with the resistors for the fan speeds to work with the new blower motor or is it just plug n play (besides the firewall hole enlargement)? I plan on just taking the lower box apart and leave the upper assembly in place as this is my daily driver. Thanks a bunch

[@UCanDoIt2Mike]

Sounds like you have a good overall plan. As long as your resisters are in good shape, it will work as is with the new motor. If not, they are easily accessible to swap later. Mine worked when I dismantled, so I assume they will be good for a little while longer. The lower Heater Box has most of the items that need updating. Cheers and have fun with yours! Mike

[@wescollins23]

@@UCanDoIt2Mike just got the heater box installed, wow what a difference. Between the old core being full of junk internally as well as the fins, the weaker fan, and the degraded foam, it is like a new world in my jeep. I live in NW Colorado so this is a big deal! I did not have issues overheating but the jeep even seems to be running slightly cooler. Defrost that works is nice also... I did a couple of different things from you as well that I will mention in case someone else wants to try. I blocked off the small 1x3 opening since I added the lower duct. I added a piece of foam on the bottom of the angled piece of the defrost gate. Lastly, I filled the void above the squirrel cage with foam insulation. I figured best case it might deaden the noise slightly. Overall, this is a great upgrade and I wish I had done it several months ago. I appreciate the effort you put into the video and instructions.

[@UCanDoIt2Mike]

It will definitely be nice to have extra heat when you need it. Cheers and thanks for the extra info and to know that it appears to be a worthwhile upgrade.... Mike!!

How much more difficult is it to remove/install the upper assembly if you don't remove the dashboard? Will it get snagged on the wiring harness, instrument cluster, etc.?

[@UCanDoIt2Mike]

Not to my understanding. While I was not in that situation, I have seen examples of being able to remove both the lower heater box and the upper fresh air duct from the Jeep without issues of the wiring harness. From what I’ve experience, I also believe that to be very possible.

[@natevanness]

@@UCanDoIt2Mike Thanks! I have a 1980 CJ 7 and this is a sorely needed project that has intimidated me for awhile

[@jimjohnston3188]

Mike, Maybe you can answer a question for me. A previous owner replaced the CJ tub with a YJ tub and along with it a number of assemblies. Originally I thought the heater box was from a CJ, but now I think it's from a YJ. Although the push/pull knobs open and close the vent doors outside on the cowl. The actual heater box doesn't look like a CJ box, the levers that control the doors are completely different. Plus I can't find any trace of flexible ductwork going up to the defroster ports. We're these assemblies interchangeable? I was planning on using your videos as a step by step way to rebuild my heater box. Jim

[@UCanDoIt2Mike]

I'm not 100% on this, but let me tell you what I think. The Boxes are different. The way that the Control Cables connect to the box are a little different. You should be able to just purchase the YJ style, if that is the case. Where the Control knobs attach to the dash would be interchangeable. I believe the YJ Heater Box and Fresh Air Duct will physically fit in the same space on the CJ, there may has been some minor adjustments to the 4 mounting holes and the large hole where the Blower motor pokes through the firewall. My guess would be that it just drops in. I am pretty sure that you will find the two boxes (YJ and CJ) are extremely similar. My video should be 95% of what you need and then you can make up the rest. I had never done it before. I learned most of it while I took it apart. I say Go-For It! Enjoy!!!!! Mike

Is the blower wheel in the picture identical to the one that you used? My wheel looks like your original wheel that you removed.

After re-watching the video I see that you reused your original fan wheel, which is the same as my original. If you notice the picture in your material list, the center of the new fan wheel is offset. I do not think it is the correct wheel and I am having a heck of a time finding the correct one.

Each cable housing is typically “held” firm somewhere very close to the looped/door end. Just like that same type of housing/cable solution would be used as a lawn mower throttle cable.
