Outstanding! This video is the standard for how all repair videos should be done. Great camera angles and voice-over which eliminates background and wind noise.
Funny thing is, I was talking throughout the whole video but the audio was not that good, so I decided to record myself as I watched the video basically narrating what I was doing. I really appreciate the positive feedback 🍻
i just did this yesterday on my 02 Tahoe, except I had to do to change out the txv valve on the evaporator coil. I had the refrigerant recovered, but I did not want to disconnect the heater hoses from under the vehicle to pull the hole box, so I pulled the front half of the top and cut the bottom half of the box with a Dremel tool just enough to be able to get wrenches on the txv valve nuts. Once I changed out the valve I taped up the box where I cut it with EPDM tape....sounds bad, but it sealed up really well. I wish I would have seen this video before I did mine I probably would have taken it apart like you did, the whole top half. I had a tough time getting the dampers line back in the holes on the side of the box. Either way it is quite a project. Thanks for posting.
Excellent video tutorial. I can't thank you enough for putting the time and effort in to produce this step by step narration and the fact that you didn't add some obnoxious audio to the background is Absolute Golden. Thank YOU... The bonus comes at 12:08 when the girl has just got to go... she goes... Thanks again.
Lol.... I never even noticed that before. I took me a minute to figure what you ment 😅. I appreciate the positive comment 🍻
The best tutorial I’ve seen I’ll be tackling this project this weekend!! Thanks
Good luck man.... Cheers to fixing things yourself beer 🍻
Good job man i had to do the same on my wife's tahoe. Now I'm fighting with the module today no heat.
Yea these suv's have some quirky things that go wrong with them. Fortunately most are easy enough fixes we can do ourselves.
Very helpful, thanks for posting
Great job 👏 keep it up this is truly the best one ive ever watched
Appreciate the positive feedback 🍻
Thank you so much what an awesome guy!!!!
This is a real good video - great job !!!
Greatly appreciate the positive feedback 🍻
Cool man thanks for the info!
The original piece had a white block of foam. The replacement piece doesn't have that. I would assume it would be a good idea to remove the foam from the original piece and superglue it to the new piece? I assume it's there for the plastic trim to help support it or maybe to help with noise.
Awesome video man thank u so much
Appreciate the positive feedback 🍻
Good video helped a lot just in a respected way just wanted to add a little more just make sure before putting it back together make sure you blow out any dirt, dust, etc.. especially the evaporator it we’ll help a lot.
That is definitely a good tip! Appreciate the positive feedback 🍻
This truck is a beauty!
Much appreciated.... It's old but I try to keep it nice! 🍻
I own a 2002 GMC Yukon one owner from dealer. it’s in mint condition has the slt interior wish I’d had a sunroof
@@Bassingtv that's awesome... You know everything done or not done to the vehicle. I bought mine with about 120k miles and it has 195k now. It took me a little while to fix all the little things but for the most part everything works as it should. I'm hoping it keeps on trucking because I do love my yukon!
SUPER VID I have not been able to use my rear ac for YEAR due to it howling and grinding. I watched and changed my rear fan motor, swapped over the cage fan, and re-installed it all in like 15 mins flat. Big like. Note I went too fast taking off the inside plastic shells and split the one running vertically behind the middle seat row. But I'll live to see another junkyard. LOL BIG LIKE..!!, FYI I just changed a compressor kit and I omitted to tackle the TXV that came with it for the rear coil I assume. I'm feeling guilty for not replacing it now cause too late I am not discharging the system again no way. I did not see that in your vid. Was it down in there on the back side of the a/c coil? No biggie just chatting. I also did not realize how hard it is to actually access the rear a/c evap coil.
Honestly it's been so long since I did this I don't even remember and hopefully I never have to figure it out 🤞. Glad the video helped you out even if only a little 🍻
Super helpful man. Thanks.
Definitely appreciate the positive feedback 🍻
Do you know the part number or name of that piece you replaced. Looking to order one. Thank you.

Good job bro, step step commentary other people should do your style of explaining what the steps sre for anything and everything it helps sooo much good job bro👍👍
Glad you liked it 😁
This helped alot thanks
Awes man, glad it helped!
Three tips from doing this myself on a 2003 Chevrolet Tahoe LT, and perhaps in contradiction to what was expressed on this video:
1) Pulling the HVAC/ECAS fuse did not initiate the recalibration of the rear controls. However when I pulled the negative of the battery for just a minute, then reconnected, and started the engine, the actuator swept over to match the position called out on the controls within about 20-30 seconds of having started the vehicle.
2) Before placing the new Auxiliary Air Conditioning Evaporator and Blower Upper Case (GM #88891577) assembly into position, pre-load the three (3) clips along the rear into the lower half section and retain each with a small strip of duct tape. Each clip should then remain locked into the lower half, upright, and at a slightly outward angle. Lower the new upper half into position and mate it with the plastic alignment dowel pins around the base. Then when reaching through the center of the fan area to access the rear area and secure the clips, they will be already located exactly where they need to be and by applying a significant amount of finger pressure, the clip will roll into the upper part of the case right into the nested space.
3) If you have chosen to replace both actuators while the trim is off (because everything is 20 years old now) I recommend obtaining an OEM actuator GM 89018375. While there are actuators on the market for $90 less than OEM version, the aftermarket case does not sit squarely on the mounts for the blend door. The aftermarket does work well on the mode door though, so if you want to save money, do it on the mode door.
The more information the better! Thank you for the tips 😊
Any suggestions for the front ac? It blows at cold when running but when stopped in traffic it comes out hot after a while.
Sounds like you are either low on refrigerant or maybe the office tube is plugged up. If you have a clutch fan ,that could also be bad as well.
Just came across this video! My rear AC doesn't work either so I will definitely be checking this out! Thank you so much man!
Good luck with the fix!
Man. My Tahoe needs this now. I just found out the post for the temperature actuator is gone. Has a hole. No post.
Yup that's exactly what happened to mine this is the fix!
So what was not working the fan blower? My Yukon blows hot air only in the back the front works, I’m not sure what was the problem with yours
Mine was blowing just hot air. When I pulled everything apart I realized the blend door was completely broken and stuck on heat. You could also have a bad actuator that operates the blend door. Only way to know is to pull it apart. Definitely reset the system first before you pull anything apart. Sometimes the actuators get stuck and just need to be reset. You can look up videos to reset hvac system for these tahoe/yukons on TH-cam.
Hoping you're still checking comments. I'm dealing with only getting heat out of my rear/roof, can't get AC, '03 Yukon . AC blows hard and cold through all other vents. Was that your issue? Changed actuators and front ceiling control module, but no luck. Thinking its this blend door issue, but could also be the HVAC control module. Thoughts on if I need to do the whole housing like you?
If you already checked the rear blend door actuator than yes it's probably the blend door like mine was. If not, I would pull that rear panel and check it out.
@@T_B_C_L I appreciate it! As many others said, awesome video!
@@leelariviere555 let me know if you have any other questions. Good luck 🍀
My rear fan is blowing but blowing hot air when I have on cold air. Will this fix it? Please help.
You need to pull the rear panel off and troubleshoot exactly what's wrong. It could be this or maybe just the actuator.
My 2012 Tahoe front A/C works fine. But the rear A/C only blows hot air. Any recommendations? Thank you sir.
I'm sure troubleshooting is similar to mine but I never have done it on those years. I wish I could be of more help ☹️
@@T_B_C_L Thank you so much for helping me out. It was your video what resolved my A/C problem. In my case it was the hot/cold actuator. It was stuck on the hot air position. I was not able to remove the darn thing because in my model, the actuators are installed in the opposite side when compared to your unit. The other actuator (up or down air flow) works fine.
@@jexmartinez9343 glad you figured it out! Sucks not have a/c in the back of these big vehicles!
My front ac blows nice and cold. And it blows plenty warm when turned to heat. But my rear doesnt blow at all, not hot or cold. 2000 gmc yukon xl 2500. What could it be? Doesnt sound like the blower motor comes on at all.
It could be a number of things but I would start by checking the fuses. I believe there is a 30 amp blower motor fuse and a 10 amp hvac fuse to the left of the steering column. If those are good then pull all the hvac fuse and leave out for a minute to reset the system. If this doesn't work it could be the actual blower motor.
Perfect!!! Thanks for posting this!!!! Where did you purchase your housing?
I found it best price on ebay but It can be purchesd from Amazon or other online retailers. I believe I paid about $91.50 shipped. "partscenterplus" was the seller.
@@T_B_C_L Thanks!!!! Watching your video one more time to make sure I can do this myself. You sure make it look easy.
@@tsuniecey if you have any question don't hesitate to ask!
@@T_B_C_L Man, I feel like I owe you some money!!! Aside from the three clips on the back side (screw that third one, I'm rolling with two), and that one screw above the wheel well, that was a pretty fast and easy fix. My beer didn't even get hot!!
Thanks a ton for posting
@@tsuniecey awesome man just awesome.... This is the whole reason I put these videos up.... To help the next guy as many have helped me as well! LET THE A/C BLOW!!
Hi, can you please tell me where that wire with the brown foam tape goes? It is located at the back of the housing towards the tailgate
I think you are talking about the cigarette / 12v outlet that should be located on the panel
@@T_B_C_L thank you, you are correct.

Did you get a noisy rattle when you would step on the gas? mine does it only when I have the a/c on so am getting my comp is going out
Noisy rattle 🤔.... Could be the clutch on the compressor or even pre ignition ping from low octane fuel, idler pulley can rattle as well. I've had my fair share of finding annoying rattles. Unfortunately they are usually far away from where you think. Hopefully you will get it figured out 😉
It’s funny cause it only does it with ac running that’s how I know it’s not my engine so far so I replaced tension pulleys for a/c and belts so my second guess is probably the comp is going out
@@Bassingtv you are most likely right but in the past when I thought I had it figured out.... It ended up being something totally different. I have a ticking sound in mine when I use the ac as well and it drove me nuts because I couldn't figure out what it was. 99 out of a 100 my hvac is set to front vents and it made this ticking noise. But one day I didn't hear it but the next I did. Well I finally figured it out because I had used my defroster the day before. It's the dumb blend door actuator that ticks when it's on vent and only when on vent. I usual just keep it on vent and floor settings and no tick.... 😂
Did you loosen any hoses or anything On the bottom outside?
No I did not
Dog taking a leak at 12:07 check the reflection on the window 🤣🤣
My rear AC recently has no power. I have a 2003 GMC YUKON DENALI AWD. How do I fix it? Thanks
Do you mean no power as in you turn the fan speed up on the rear and no air blows? If so I would definitely make sure all fuses are good and check power with the blower motor. Could possibly be the resistor as well. Unfortunately you will have to take the panels off as I did to check those things. Just use a test light or simple volt/ohms meter.
@@T_B_C_L Will do. Thanks for taking the time to respond to help all of us. Good looking out bro!
Mine doesn’t blow at all changing this will fix it ?
If it doesn't blow at all, you need to check your blower motor.
Hey man I know this video was posted 2yrs ago but I wanted to ask if this repair can fix the ac blowing only hot air in the back for a chevy tahoe
Only the front ac blows cold
@@DavidMartinez-rq5dl most likely yes. You need to remove that cover to see if it's the actuator thats bad or the blend door like in mine. My yukon also only blew hot air in the rear while the front had heat and a/c.
@@T_B_C_L thank you for taking the time to reply man, I'm 18 and just getting into mechanics so these videos are very helpful thank you so much, will keep supporting 👍🏼
@@DavidMartinez-rq5dl anytime my man. I will definitely try to help you out if you run into any problems!

Omgoodness thank you so much! I really appreciate it! God bless u!
@@torimedrano3871 anytime.... 😊
My rear AC just stopped working I wonder if this is my issue or it’s just that actuator
Depends....does the blower still blow air? Is the air hot or cold if it does? If the air blows and it's stuck on hot listen closely back we're that actuator would be and see if you hear a clicking noise when you switch from hot to cold. You can diagnose 80% of the issue before taking anything apart. Good luck.
The Blue Collar Life this is what mine does! What do I do to get it to blow cold
@@jamiecombs6901 you gotta troubleshoot it man!
Yeah this vid. How did you diagnose that it wasn't the actuators?
I pulled it all apart and cycled the temperature and could see the actuator working. I then proceeded to remove the actuator and noticed the mechanism was broken. It's impossible to diagnose without pulling that panels off.
It's in the video.
Whats the name of that whole pease you just put on?
www.amazon.com/dp/B000QH5U2A/ref=cm_sw_r_apan_i_J919BBYBS3V8J1KCJ7RQ
My back vents don’t blow at all any suggestions
You mean the blower motor does not kick on at all?
Where did u get your radio from?
I think that was my old radio. It was in the truck when I bought it.
My 00 suburban rare fan doesn't turn on ever since I bought it 5 years ago but the front dose 🤦🏿♂️
Sounds like the same problem I've been having. I learned that it's not getting power.
3 years later and youtube shows me this comment 🤦♂️. Hope you got it figured out.
Did you buy your rear blend door actuator from ebay, too ???
I did not buy the actuator. I swapped the blend door actuator with the overhead feet actuator as I never switch away from overhead. They are same exact actuator.
I did not have to loosen any hoses from underneath the vehicle.
@@T_B_C_L
Thanks a lot, bro..
@@MrYAZZ-hl7pw if you have any questions man I'll do my best to answer them!
@@T_B_C_L
Yes Sir. You got it. I will do that. I am ordering the part from ebay now. So, hopefully this week. I should be able to fix it. With Your Help. Thanks Again, bro. 👍
Does that box hit hard ?
Depends what you interpretation of hit hard is. I've had 4 15s that I would say hit hard. This doesn't hit nothing like that. I would say that it hits hard enough that if it hit any harder I would have to dynamat the whole back to stop all the rattling!
How much for the replacement parts?
Like $90.
Would you happen to have the link to the part ?
GENERAL MOTORS 88891577 CASEAUX A C EVPR BLO UPR a.co/d/8bovh2w
It aint $91 anymore. Looks I am off to the junk yard. Not paying $150 for a plastic shell. But who knows what I will find at the parts graveyard. May end up forking over the cash anyway! I may have found it for $89 from GM Parts Direct.
Maybe you can do mine now 😀
What if ur front ac blows cold for a while then starts blowing hot and when on heat it will blow hot for a while then start blowing cold 🤔
Unfortunately that sounds like the blend door actuator which is on top of the hvac box. I have seen a video where a guy went in through the vent and changed it. Other than that you gotta pull the dash. Same as if you needed to change the heater core or ac condenser! Good luck.
I was just thinking you definitely try reseting your system Before doing anything else. Follow this procedure
th-cam.com/video/gFsHHcpAzPY/w-d-xo.html
Why did you replace the housing and not just the fan and actutator?
The fan and actuator were not the issue. The issue was the blend door was completely broken and the only way to fix it is to replace the housing!
The answer is in the video. Be honest, you just scrolled through it, didn't you?
What was bad in the box you replaced?
The flap that controls if hot or cold air comes out of the rear was broken. It's the part that the actuator connects to.
@@T_B_C_L Oh ok my Tahoe 03 only blows hot air in the back,the fronts cold i need check that.
@@roltyd22 usually it's either the flap mechanism or the actuator... Good luck 🍻
@@T_B_C_L Thanks for the video !!
@@T_B_C_L I have the same issue, took off the actuator and it looks like the part in the box is pushed in...does that indicate the flap is broken? New actuator, no change. I can only assume this is the issue because when I installed the new actuator it just pushed in. no need to calibrate.
What's the name of the part?
www.ebay.com/itm/323928566977
My rear heater works but my ac is just regular air in rear. My Front is ice cold.
You need to try to reset the actuators before you do anything else. If you have automatic climate control like mine, push the auto button on the climate controls and make sure it says auto at the bottom of the little screen now turn off the vehicle and remove key. Next go under the hood to the fuse box and remove the 10amp fuse that's labeled hvac/ecas. Wait for 1 minute and now reinsert fuse and start vehicle. That's is the reset process. If it at this point the cool air does not come from above vents go to the back where on my video you can estimate where the actuator is. Now have another person change rear temp knob from cold to hot waiting a few seconds in between while you listen closely to see if you can hear the actuator. If it's clicking it has gone past its maximum travel and either broken or stuck. On the rear you have 2 actuators one for cool hot air and one for overhead vents or floor. They are the same exact actuator. If the fan changes from floor to overhead then that actuator works, you could swap the actuators and just leave the setting to overhead and not mess with it. This is what I did fix my initial cool to heat problem. Or just purchase a new actuator to fix the broken one. I hope this makes sense.
@@T_B_C_L good lookin out homie
Front ac blows cold, rear ac doesn't it blows I guess room temp? But heat works on both front and rear
Sounds like either you have the same problem I had or the rear blend door actuator is stuck. Either way you gotta pull that rear panel off to check it out. Good luck.
Anyone had a problem with the rear gate not locking? All the doors lock. Just not the rear hatch. Checked the fuses and relays. It is in the rear somewhere. I haven't played around with that box underneath the rear AC yet. Probably in there. That is where the rear brake lights problem was.
Sorry man wish I had some input on it but fortunately for me I never had any issues with any of the locks. Good luck man, and I hope you get it figured out 🍻
My rear gate didn't lock bc the mechanism was rusted, I had to swap a "new" used part in
How much was the part
I paid $91 for it.
