GM lets put the heater core 1 inch from the plastic blend door so it can melt warp and snap. Great engineering!

This was the best video for doing this that I found. He doesn’t talk too much, just enough to help you if you need it and the video was good for the space you have to record. Very helpful and I completed in about 2 hours, and AC works great again!

I came back to say thanks, Chris (737mechanic)! I followed your instructions and 3 years of no A/C in this Texas heat has been resolved. Saved me $5k from my local shop. I used an electric hot knife from Amazon. Took me about 4 hours because I ended up pulling out both seats to deep vacuum and shampoo the carpets lol.

Man, you saved me a quoted $1700 to repair this. I replaced it yesterday following your incredible step-by-step video. I can't thank you enough, God bless you Brother!

Did mine in 2 hours. Great video. Used gorilla tape as a seam sealer when done. Worked great.

Someone give this guy a medal!! I could cry, I have AC and heat again for the first time in months thanks to this video (and my husband for doing the work). I almost croaked when the repair shop told me the total cost could get up into the thousands. My husband did use the weakest setting on his dremel and a bit with low profile teeth to speed up the plastic cutting, and managed to execute it perfectly.

2015 Camaro LT 65,000 mile on it, had the AC on noticed warm air/cool air mixture blowing immediate thought was low on Freon popped the hood high side of AC line ice cold. So I ordered a bore scope for my Iphone and a blend door. Most likely the blend door hinge is broken. Thanks for the awesome video. Update to come.

Man, I thank you so much for this video! $25.00 for the part and my time!!! I saw quotes upwards of $3000 to take the dash out and replace the blend door. 😢 Yikes! I followed step-by-step, and I appreciate you! May the Good LORD Bless you!

This video was a huge help and I just spent the weekend working on my 2015 Camaro RS. Followed all these tips and instructions and would have gave up for sure if I hadn’t heard and seen it done on video. Thanks for saving me a large bill at the dealer!

Great video. Dealer and another shop wanted $3000 to remove windshield and dash for a $15 blender door. I followed your instructions step by step. Used a heat X acto electric knife. Took 5 hours cuz I took my time reviewing each step. AC is Freezing now! Heater is hotter than Hell. Thank you so Much!!! Joe...So California😎

Thank you so much for this detailed video. I watched it a few times, and I just successfully did this fix on my car. I had a shop quote me 1300 to fix it, and it only cost me ~$30 and some time!

Just wanted to say thank you. Got my kids 2013 heating again. Silly me thought it was the thermostat. Thank you for your video and giving the average Joe confidence to tackle what the average person wouldn’t try!!!

OMG!!! This video is the best!!! Thank you!!! I am a female, I am a nurse, not a mechanic…. And I was able to follow step by step and fix my AC!!! I was able to get the last part back in without removing any parts, just took a little muscle… thanks again !!

For anyone that doesn’t have a scan tool. It’s not 100% necessary. All I did was disconnect battery and after finishing and connecting everything back. The only problems I encountered was tpms was all dashes and the compass was saying “CAL”. But literally after driving it for 5 seconds everything went back to normal. With the patience and tools you’ll get it done.

Great video! Thank you sooo much! My son and I just did this to his 2015 Camaro and it worked like a charm!! We were quoted 1800 to 2200 from various mechanics. It cost us $50 in parts and tools and took 3.5 hours. Awesome video, thanks so much!

First, thank you so much for taking the time out to show us how to replace the blend door. I live in the midwest and my heat stopped working about 2 yrs ago. I was very nervous about doing this myself especially with the heatee core being so close to the blend door but I was able to fix it with no issues. For any woman reading this, if I can do it so can you. Just watch his video from beginning to end first, get every tool that he suggested, remove the car seat and get a pillow for your back then go to work. It might look challenging but it's not. Might is back working now. Again, thank you so much!

Amazing video dude! I have a 2013 Camaro with 67k miles on it, it seems like most people are having this issues around 10 years give or take of use before that door breaks.

Holy smokes that was great! I believe I did watch the first video I remember you pulling that sensor out for the borescope, can’t believe how well that piece fit back on there after you cut it out, great job and thanks for sharing your knowledge and skills with us!

Really good video, you went through each step. I would use whatever you are using to reseal the plastic, in the little holes on the door where it breaks to reinforce it from breaking again.

I finally replaced my blend door last night. I started at 9:45p and by 11:30p the new part was in and secured. I think I could have knocked this out even quicker but a few things held me up. 1. The plastic piece that you cut off to access the blend door, TRIM it like this video suggests. I tried to put it back in without trimming it and I couldn't align it right. I fought it for a while before giving up and then trimmed it. It went in right away after. 2. The AC vent tube that is removed at the beginning needs to be put in first when you are reassembling it and the BCM pieces/wires. I tried installing the BCM first and then the vent tube and failed miserably. Once I took out the BCM (and the bracket it is in) the vent tube reattached easily. 3. Get a GOOD light. I can't stress this one enough as there is very little room down there to work in and you can't see anything without a good light you can reposition over and over to get good views of everything. If you need something good to cut the access door with, I hight recommend this ($40) plastic welder. I bought it several years ago for other projects and it worked great for this project too! There is a rounded tip that comes with it that was perfect for the job. It took me about 5 minutes to cut out the plastic piece., seriously 5 minutes if that!! www.amazon.com/gp/product/B00002N7S1/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Got the door cut and out today, wasn't too bad, took a few hours, but I didn't get in any hurry. Only thing I would add is the horizontal screw for the air duct was a Hex 20 on my car and not a 7mm. Mine is a 2012 2SS. When you get these two screws out pull down towards you and rotate clockwise, the duct comes right out. The only issue I have now is trying to fish out the broke end, and the white connector piece, but I'll tackle that tomorrow. I used the borescope and unfortunately, they both are about 1/2 way down to the passenger side, approx. 6"-7" away from the hole I cut. I tried a vacuum with an end on it that would hold them at the end without pulling them into it, but it didn't reach far enough. I guess I'll try a long screwdriver tomorrow. Thanks for the video, made it much easier to do.

I have a 2010 Camaro with the same issue. The A/C mechanic I took it to installed a valve on the heater hose, you close it for A/C and open it for heat. He said he did not know how to fix the blend door and this way was the most practical fix he knew of. Today I found this video and ordered a new blend door off Amazon. Also, when on the order page an electric hot knife popped up. So Amazon must know about this fix. It will be nice to switch from heat to A/C without having to stop and turn the valve and burn the shit out of your fingers. 😮

Amazing video. Stopped at harbor freight yesterday after watching your video to get the tools I needed and then replaced my blend door. Also I used a box cutter type tool and no heat to cut and it worked fine. That heater core is strong enough it just had some scratches on it

Best detailed mechanic video I’ve ever seen on KZfaq

Thank you for making this video. It worked perfectly. Just used it to fix my daughter’s 2015 Camaro SS. Awesome job.

Great video. I kept the module plugged in and didn’t remove the seat which made it a little challenging but several hours later I had AC. Thanks!

Hello sir! I wanted to wait till the job was done. And im currently sitting in my 13 Camaro SS enjoying full AC for the first time since I bought the car over a year ago. Thankyou. Thankyou. So much patience in telling every little detail. Perfect guide. Took me twice as long,but the job is done. You're a f*ckin saint. Stay golden.

I just did it successfully!! Planned for 3 years because I knew it would break eventually 😢

Such a helpful video. Thank you so much. I did this today and only problem I had was installing the cut back. I couldn’t seal it. I ended up just going with it unsealed and the ac and heater work. I didn’t remove the seat or disconnect the battery and everything seems fine. Thanks again.

Thank you for your video save me $3000 at the dealer. Now heat and cooling work great again. 👍🏻👍🏻👍🏻

I have to agree this is a very well and death video this man took his time show how to do it right and helping a lot of people out in this time of Overkill in expenses I'd like to say thank you

Yesssir love to see it sir! Thank you for being here for all of us Camaro bois🫡💯

thank you so much man, my 2012 camaro was having this issue and my dad and I followed your video and now my car finally has AC!!!

Thank u so much for this video. I just fixed it on my 2015 Camaro as well. Thank you for your detailed instructions.

You’re video helped fix my heat myself. You are awesome.

This was a great video. It helped me replace my door. He did a great job!!!!

I did it! yay! I thought about leaving the seat in but yeah that had to come out.. so much easier.

Man I appreciate videos like this. You save me a ton of time. Even tho you gotta hack the side of the box open it actually doesn’t look to bad after you get it back together. Thank you!

Man you are a lifesaver!!! I just knocked it out today with step by step instructions from you. Thank you so much!!

Best demo on KZfaq. Thank You ❤️

Thank you so much man!! I followed this and it totally worked. You rock my world

What an awesome video ... I gotta do this and NOW i think I can .... thank you !!!!

I feel like I owe you a beer man, thank you so much, I saved 2800 bucks and spend $100

Thank you for your video it was a lot of help to do my 2012 Chevy camaro 45th anniversary 6.2 6 SPd manuel

This was the best video I’ve seen on KZfaq saved me 1.5k quoted to me by my local Chevy dealership. Took me 4 hour but saved me all that money. Followed this video step by step and got it. Thank you !!!

You the man dude ! Thanks for the step by step

Just did this to my 2012 v6, I feel like I need to send you some $$ Thank you brother

Thank you, I was a mechanic, but now going to school for a new trade. I toke my car to the dealership, and they want to pull the dashboard out and break my windshield in the process just to get to it. I just replaced the windshield and now they want 4500 in repairs... Almost half of what i paid for the car just to get to a hvac valve. If you are aware of anything else ridiculous please 🙏 make more videos.

Great video, saved me so much money.

Thank you very much for the knowledge Sir. Great video great tips and made it very easy to do it myself. 👍🏼 God Bless You always

Awesome video! Easy to follow!

Good job I have the same problem and that will save me a lot of money

You sir are a Steely- Eyed-Missile Man! Destroyed my back, but saved a sh!t ton of money. Thank you

I used a pocket knife and a propane torch and it worked great. I think the problem is not the door but the actuator not stopping in the correct position braking the blend door.

Great video, thank you you save me a lot of money.

Tremendous help

Thanks you for this video...congratulations

Awesome thank you for the knowledge sir saved me a lot of time

This was a very helpful video and I appreciate you doing it. However I just finished doing this on my 2014 Camaro. I must say this is the hardest repair I've ever done to a vehicle in my life. I struggled almost all the way through it. Lying on my back wasn't good either it made me nauseous and sick. If someone offered me $3,000 to fix their car this way I would refuse. I did however spend the money for the billet blend door so hopefully it will never break again and if it does I know I'm not fixing it. Thanks again for your video I probably couldn't have got this done without it.

Thank you so much, my good sir 🙏

Thank you. I have no money but have a camaro hahaha 😅 so I used the torch lighter to melt the blend door pieces Back together even stronger than before and ill tell you what it looks ugly but it works great 👍 atleast there's access now

thanks, It was a great help

This video helped me change my blend door myself. I'm 58 yr old healthcare provider. I'd like to add that there is a simpler way to check if the blend door is working. Remove the cabin air filter. Have someone turn the AC to on and over to heat. You can clearly see the blend door moving. Of.course that was after I fixed it. So if it's broken. The blend door shouldn't move back and forth.

Thank You, got it done yesterday!!!

Turned a 8.5hr book time job down to 30 min thank man

Hello, great video. What is the name of the blue glue you used to put the cut back together? Thanks!!!

Great Video

Very helpful

Great video man thanks for all the tips. I did have one question though is the door suppose to be in a certain position when installed depending on what setting you have the ac on?

Dude I owe you some thanks.

Wire wheel and a gentle touch

OMG, trying to get that far end of the door into the boss has been a complete PITA!

Hey man your video is awesome! Best one out there, question though so I was able to replace that flap. And now car is blowing cold air.. but when the car is driven.. it will blow cold then hot then back to cold and keep doing that.. any idea why?

Great video!!! Quick question how did you try and run the door actuator? Did you just try and cycle through heat/acmodes?

QUESTION: am in the process of doing this repair and have hit a snag. The shaft on the actuator motor won’t align with any position that I can adjust the newly installed blend door. It's just slightly off but enough where I can’t even re-bolt the piece on. I’m thinking I can reset with a 9V battery, but can’t find the pin assignment to test. (GM Part # 92215208/ACDelco Part # 15-74128) Any advice would be appreciated. Thank you for your videos!

What size bolts does the actuator take? My mechanic stole them from me..

Panel bond, A B S adhesive, or E-6000

I can’t get my Front Driver Side Floor Air Outlet Duct back in and you skipped it in the video. Any advice?

Thank you for this video! SO detailed. I was able to knock this out in about 3 hours. Unfortunately I should've got the scope because once i got to the blend door it was perfectly fine. I replaced it anyway with the new one since i was down there. I never thought I'd actually HOPE it was my blend door. My car still blows hot air in the summer and im suspecting will blow cold air in the winter again. I'm not sure what the problem could be. Maybe it's something as simple as recharging the AC/Leak. Its a 10 year old Camaro with 92k miles. Any suggestions on what the issue could be ?

Question....are there any vacuum lines or hoses or anything that could have been nicked or cut or messed up in anyway that could have happened when a "shop" did this repair for me? Since having this repair done I've num a rous problems with my 2012 45th anniversary Ed ss. In this video I heard mention of a scan tool that resets any faults... would any such faults cause actual problems to the mechanical quality of my car? Maybe you xan tell that I've no idea about mechanics I got my dream car n since this shop "helped " me with this same problem u address jn the video it's been a nightmare. The shop is now shut down closed up gone bye bye so I've little recourse n fewer dollars to spare going to gm or Chevy is obviously the biggest fear in my nightmare. Please any help or suggestions would be greatly appreciated. I've got "stabilitrack" lights n messages as well as engine codes 303 n 353 which h from another video I saw say a they're all connected believe it or not n yes I've done spark plugs n tune up n compression Tests. Any ideas welcome. Thank in advance

Update...be very careful like he said on heat core when cutting. I didn't peirce the heat core but a peice of plastic that was covering that side broke off. Now when I put it together my heat works yes, but now my coolant is leaking with it the vent and it's blowing smoke....now I have to figure a way to patch it up

Holy crap!! This repair is a true p.i.t.a.!!You couldn’t pay me to do 8 of these terrible just terrible to put yourself through such pain. Thank you for the walk through but this is way more intense then I thought took me 4 hours and I’m no rookie or well atleast I wasn’t until this happened 😂

Just recently did this repair and while my air is still a bit cool compared to what it was, is it possible if you didn’t seal that plastic back up that the air that’s escaping could be coming in contact with the heater core resulting in it blowing warmer than it should? That’s literally the only thing I didn’t do and it started off fairly cool but today it felt warm again. The door seems to work cause I can tell the difference in temp otherwise.

Any tips on unclogging ac drain? Have water spitting out vents.

If your close to spring tx and taking work. I have camero that needs one done.

What is a safe length to use on the exacto knife to not pierce the heater core? I’ll be attempting to do this in two weeks and damaging the heater core is what worries me the most.

Thank you sir 👍🙏🤝🤝🤝

Gave a like and subscribe bc you probably just saved me $400 bucks

What size bore scope?

Hey man I need help , do you think the blend door would be a reason for the clutch not to turn on the compressor?, I changed ac pressure switch , the clutch on compressor not engaging . I even tried to jump the compressor. But the weird thing is it engaged for the first time , I saw .. a few days ago ,when it was kinda cool outside.. 1st time ever since I had my Camaro since January .. i need all kinds of advice , trying to get it done this week before this 110 degree weather end me 😭

would you be able to use a dremel to cut the piece out instead of a hot knife ?

Hey I need to know have you done these on the 2011-2013 Jeep Grand Cherokee? They’re infamous for these problems and I’d love to know if you have done them before. Thanks!

Lifesaver , currently 35 degrees in my state and I would’ve been frozen to my seat if it wasn’t for you . One question , what is the duct meant for ? Sure was a b**** to get out and in ! Thanks again !

Does the actuator fits in any position the door is? Does it matter? Or you need to keep the door closed so the actuator engages in? Do you need to recalibrate with the scanner after you finish installing it? Thanks

My 2015 SS with 45k broke blend door, new england weather 😢 enough, brittle cheap plasic. I am certain it will break again, i am definitely NOT removing dashboard. My mechanic, will do this. I will show him video

Got the Boroscope today, what position should the camera that's on the side of it be positioned? I tried it from 9 o'clock to 3 o'clock and still could find the far end of the door to see if it was broken.

Hello if cold air coming out from one side and hot from the other does it mean the actuator is Brocken?

How can I get past the relearn stage ? I don’t have a scan tool to do last part plan on fixing my blend door this week.

How did you know where to plug up the connectors back into the body control module? I see they are all different colors but how did you know you weren't plugging the connector into the wrong spot
