These jobs are a Mechanics Nightmare !!!! Nobody really appreciates the real effort invested until they see it !!!!!!! Thanks for the Video !!!!! Been there , Done it !!!!! God Bless !!!!!!!😲😲😲😲😲😲😲

Dude you my hero, I was dreading changing the wifes heater core, everyone told me it was a 2 day job ,watched your vid 3 times,,, in and out by myself 6 hrs.Thanx

After watching this video for a month I finally build up the courage to dive into this job. THANKS for the video my friend it help a BUNCH. Keep up the great work, quality videos like this one are greatly appreciated. Thanks again.

Brian you're my hero. I spent 7 hours today..just me, you and my jeep. Got in and out no major problems.

Thanks for taking the time to put this together. I know that dragged the job down, but you truly have helped out folks get a few more years before biting the big one with a vehicle purchase.

I appreciate the effort to put this video together. It was a great help with my '02. It took me 9h from start to finish and I came close to finishing in 3. The vid sure helps removal of the dash, putting it back was more challenging. TIP: document when every screw came from. There are lots and it is easy to lose track of where they come from.

Can’t thank you enough for the video. Changed the core in daughters 2001 JGC. Seriously don’t think I would/could have done it without the tutorial. Plus my wife and I would laugh at the extras you threw in there. Thanks again.

You are the man!!!! I watched your video on the F4i timing chain like 3 years ago! This is my second grand cherokee heater core. I actually didn't check the condensation tube after the install and had water puring out of that bucket on the P-side floor board LOL. Your video is a refresher course!!! Thanks!!!

I know this is an old video but know that it's still helping out a ton in the JGC world! It made the task an absolute breeze, just knowing upfront where every fastener is, or what harness needs to be disconnected is more than half the battle. Really appreciate the video and the level of detail. Thank you!!

Thank you for the video!! Needed to change the heater core in my daughters Jeep and the shop wants 3/4ths what it’s worth to do this work. With the help of your video I was able to do it mostly myself in 6 1/2 hours. My back hates me, but I saved a boat load of money

Video helped me a lot! Did the heater core swap this weekend, son's 2001 Cherokee. Thanks so much for posting.

Hey man had an issue with no air and heat in my jeep. This video summed up my issues and I like how you took the time to explain the air system and all plugs / actuators and what they do very informative and helps me get the job done faster !!!

Just got the dash out on an '00 Grand Cherokee. Yes, that plastic clip on the passenger side was a real bugger! Thanks for making this video! It was very helpful!

Thanks a million for the video! That one lonely bolt up above and just to the right of the steering column had me stumped for a while!!! Enjoyed the rambling commentary as well. Awesome job!

I watched the video and it helped me a lot with getting the heater core out of my wife's jeep and I would like to thank you for your time and effort put the video together. Thanks Joe ladd

Thanks Brian, your video helped me do the heater core in my '00 4.0 WJ in 6.5 hours, though I still have to put the console back in.

Dude out of all the videos i have watched about this job. None of them are this detailed in how to do it. 10/10

thanks for posting this video. I replaced my heater core today, and this was a huge help.

This is one of the best disassembly videos I have ever seen bar none! Excellent job! Thanks for all of your effort!

As a young mechanic this is exactly the video I'm looking for, thank you very much!!

Thanks Brian for the video getting ready to tackle mine on my 2001 jeep Cherokee, just installed a new 4.7 engine and realized there is antifreeze coming out of the frame under the carpet looked under the carpet to find a puddle, I must have busted one of the heater core lines in the process. The video had great detail appreciate it...

I'm getting ready to tackle this job and this video is absolutely helpful. Thanks for making this.

This video helped me greatly today. thanks for posting. Though it took me approx.12 hours to complete- its DONE, just in time for winter.

The WJ is famous for the foam going to shit, blend doors biting the dust also. I fixed all this with my 04, real fun! Blocked the vents going to the back and with new foam sealing it blows like the noise suggests it should now.

brian you are a legend for doing this video thank you so much. I pulled my dash apart but the wiring harness got stuck so i really had to take it extra apart and was afraid i wouldnt be able to figure out where everything went back. I think i will though but your video is awesome, I know i will be able to get mine back together now thanks!

Thank you so much for sharing, this has been an invaluable tool for this project

Great Video, Thanks for taking the Time!!! Extremely Helpful!!!

Now this guy can explain things right !!!!! Good job freind

thank you for the detailed how to sir.Feel better about attempting this this weekend.

Wow tons of work. Thank you.

Great video. It’s going to help drastically this weekend when I do this to my jgc.

Thank you very much! Ridiculously helpful!

Excellent video on the jeep, much appreciated, Thank you.

love your vids, informative and funny. Ive been twisten wrenches for a living for over thirty years (oh my) and its hard to find humor in drawing blood unintentionaly from ones self. or in having deisel fuel run into your armpit while laying in a snow bank. just bought a jeep cheeroke and the guy says he thinks it may have a core leak. took off the radiator cap and found a puddle of stop leak.. no pressure test required here! Ill have you and the laptop on the dash while I work...thanks, bob the builder

ABSOLUTELY GREAT JOB ON THIS VIDEO!!!!! This has calmed my nerves down a bit. 20 years ago, it wouldn't have even been a thought for me to just simply jump in and make things happen, but these days, I don't move like I used too, and it has been many years sense I had to yank a dash for this issue and was actually dreading it, especially with the idea that it was calling for 5 to 10 hours, pending who you talk to, which for me meant that it was going to take like 10 to 20 hours.... lol... but, you really made this look smooth, the fact that you stayed at it for the 30 or so minutes... I will be completely content if it takes me 3 hours to get the dash out of my way... never mind putting it back together... Thank you for taking the time and the surgical effort with the camera.. I am writing this on 01-08-20016, it is gonna be a few weeks before I actually get into this on mine, as I am finalizing some other issue, so I kindly ask, will you and your wife keep this video up for a while? I will post back here to mention how I did, based on following your instructions, lol... and then you can remove the video... just kidding, keep it posted, the narration that you did, step by step and the reasons why for each step, this video will help many folk out of heart ache. Great job! Drew

Will be doing this this weekend on a 2002. Hopefully this vid will help me get the job done!!!

While this may be my longest video yet, the hope is that it may help someone to fix their own heater core even though they don't have hundreds of dollars to pay someone else to do it. Thus having defrost this winter and being safer themselves as well as protecting others as well. It's long, but it's good reference material considering it's a 4.7 hour job. I did edit as much transition fluff as I could. There's shooting competition bonus footage at the end. For more of that stuff visit my other channel in the description "theskiviking." Thanks!

YOU were the only one that's did it right I've found in 2 years recently 👏 KUDOS AND thanks

Brother you've been most helpful. I watch some videos and I follow their lead it took me to the unknown! I watch your video and it helped me out tremendously thank you very much!!

I am about to rebuild my entire hvac box in a dual climate 02 WJ. This video will help.

just did mine today.. Followed the vid and it went fine. Thanks

Thank the Lord for your video after watching it I tackled the job and it went great thank you

Great job and super helpful

Great vids, thanks for sharing and keeping them G rated.

Excellently unfolded

Thanks so much Brian. This video was really helpful. I just did this job on the same model Jeep. It took me two long days. The guys who installed an alarm years ago ran wiring through the bracket that's mounted below the steering wheel so I had to cut and rewire. I also had to apply new foam onto a few of the blend doors because they were soaked with coolant. When I finally got it installed there was one connector I couldn't find. It's under the glove box next to what you called the HVAC motor switch, I believe. I connected the white one and a black one which plugs into a unit under, but there is that one loose one I can't find the mate for. It's black on the outside and blue inside. I'm pretty sure it has something to do with the HVAC motor also because it's not working. Also, would the engine overheat if I put the heater hoses on the wrong inlet/outlets? Thanks again for all your help.

You have something I'm light on Brian. Memory. I couldn't begin to remember where all those fasteners go. I try to have a system for that. My latest project since the transmission rebuild is replacing interior overhead and license plate pocket lights in my van with my own home made LED's. It all came out real nice and is brighter than the stock lights. I also made my own adapters to replace the glass fuses with blade type circuit breakers. They snap into those fuse clips just right. I won't be buying any more light bulbs or fuses. 3 gun is way fun. I'm shooting sporting clays tomorrow. Get better pal.

Impressive skills Brian - Thanks....The ending was pretty cool too!

thanks, from Scotland

WOW! Not looking forward to replacing the heater core. However, I am tired of vacuuming the coolant off the floor....Very nice job and you have a great attitude. Really liked this long video. Persistence - the key to Success.. Thanks!

great Video!!!!!!! thank you very much for all the little details !!!!!!!!!!

Best video I've seen. I have been following along here. I have some friends coming to help out to finish it but thanks to this video I've been able to get started on my own. Now if I could just get those damn hoses off!

Wow, good job, complete. Amazing what needs to be done. Good time to change the turn flasher also.

loved the vidieo just got a 2002 wj and it needed blend door replacement from the dealer I see know how much needed to do it just in case.glad they did it!!!it seems they made them with cheap plastic parts but the replacement parts are made with metal which is good,, thanksfor good vid...snooker out...

Awesome job on this video. I have to replace mine, so I'll be staring at this for the next couple of months. Thanks dude.

Just finished this up yesterday using your video as a main reference. Just wanted to say thanks for the great job. It was a massive help. I had to do pretty much the same thing to my wife's Equinox a few years ago to replace a blend door so I had a pretty good idea what I was in for. Thanks again!

Very good video. Thank`s

After seeing you and Eric the Car Guy put yourselves through all of that just for a heater core, it must be the most dreaded job in car repair. Feel better Brian. Now that the job's done take a much deserved break.

Brain, hello sir. I am using this video to replace my son's heater core in his '02, but 2 little brass clips fell from some plug I believe while removing the steering column. Thanks, Jim

Thank you for the video! Very in-depth, very detailed. Would be much of a help for me.

Nice video Brian! Don't think I'll be doing this job any time soon. Beyond my scope of practice. Chrysler junk. Subaru, Toyota, Honda and Mazda. In that order.

Very cool! Thank you! AllData is vague as all hell lol

Love the video. I just bought a 99 Jeep Grand Cherokee. It has heating problems. I thought it was the heater core. So I went and got one. I have not changed it yet. The other day I turn the temperature control knob from heat to cold and got good heat and when you turn the knob the other way you get cold. I don’t know if anyone has work on this Jeep heater before. Was wondering if you mite have any idea what it mite be? I don’t know if I have a vacuum or electrical problem.

I managed to get the dash out and down to the HVAC box myself without any references, but I watched this hoping to see if I could avoid disconnecting the AC to swap out the heater core. Based on this video, I see that is not at all possible. FML lol thanks for posting, still great info.

You're the best, bro)). I want to work in your car service)))

Ive done these before in the past but not for a long time… ive watched your vid before and needed a refresher. Im unfortunately doing one on a V8 and im also not im the mood for it

Brian your video's are awesome..

Thank you AMOR 505

Great video Brian but I think if I need this done I will drive the 789 miles from my house to yours and tell my wife were on vacation. Get to feeling 100% again, and always glad to see Spanky.

Brian Great job on heater core Please help with much smaller job Heater resistor seems like it should be easy but cant find the two screws holding it in 98 grand cherokee limited with auto temp

Good job.

Good video. Only thing o would recommend...check your blend doors and take an air compressor if you have one, and blow alot of air to clear out leaves and debris. Thoroughly check everything because you do not want to have to take it back apart. Blend door actuator is known to fail on these jeeps as well as the blend doors break. Good luck! If I can do it, and this guy can do it. So can you. Basic tools...nothing special....just need ac recharged n coolant topped off, be sure to bleed coolant well....

Dude you should be an instructor. Great video. Thanks for making it.

You did a great job explaining and showing how to do this job I wish you would have had a list of what tools were needed but I guess every wife has aggravating friends

Just came across this video thank you very much it was very helpful I'm not going to replace my heater core I rather sell it to the junkyard LOL

Nice. I appreciate you posting tool links, think I'm gonna need a bigger box sometime. lol My mother has a 2000 explorer she has similar problem but source of her slime on inside windshield is from smoking.

Hey Brian, great video ! I have a good one here , someone messed up the driver door to body wiring . Slit the rubber boot cut the wires to short , now need to replace body to door wiring harness ! Has connector that plugs into door harness , that's easy . What all has to be done to replace harness under dash . Are there connectors or spliced in ?

Great Star Wars/chinese finger trap picture !!!!!
