I completed this exact job today and your video saved me. I took the laptop out to the carport and followed your directions. Had no problems whatsoever! I went to O'reillys and bought the module for about $80 bucks, I probably could have ordered it on Amazon or some place else and paid a cheaper price but the wind is blowing about 35 mph and it's about 20 degrees outside, so I was just happy to get it done. I was out this morning at 4:30 AM and it was raining and my windows were fogging up so bad because I had no blower, I had to pull over and wipe the inside windows. The rear air in my suburban would heat the vehicle just fine but it didn't de-fog the windshield. Thanks for your video!
This has been an on going problem for me for about 2 years now. I have a 06 Cadillac Escalade, I seem to be changing this thing once every 6 months. Thankfully the part has a life time warranty. I have even changed the blower motor. What happens is some days it will blow some it wont. Or I'll be driving and it will come on then off. Then back on for a few minutes then off again. The only thing I haven't changed was the controls on the dash. I never new that about the volt meter, so I guess that will be next. Thanks, Great video.
Hey Eric, Thanks for this awesome video. I didn't have all the tester tools that you had but after watching the video i was pretty sure that my pickup was having the very same issue. Ordered the part on eBay and within 15 minutes of receiving the part in the mail i was back in the cool zone with the AC blasting!!!
Thank you very much for putting this onRUclips I have a 2005 Chevy avalanche and the heater went out just as you explaining in your video because of you posting this video I was able to fix it for $35 buying the part from amazon.com whereas the part cost $85 from a parts store thank you very much and keep posting thumbs up subscribe
well done tutorial. I appreciate great camera work, thorough analysis, talking your way thru the troubleshooting process. Well done. What website do you use for your wiring diagrams? (PS turn off the G&R it makes it hard to hear your video) THanks
I figured it out. I thought you were crimping 2 wire set that plus into blower itself but you were crimping wires to what was the wire plug into module. - thanks,
Fixed my problem on my 05 Yukon Xl Denali. Front Ac would only work at highway speeds. My assumption was that it wasn’t getting enough voltage at a standstill. Ordered part off carparts and Installed today. I used the yellow butt connectors instead of blue. Ac blowing super cold again. Anyone with the problem with ac only working while driving, swap out this part. Summer isn’t dreadful anymore lol
I'm having the same problem with my rear air not blowing. Changed everything from a tahoe in a salvage yard still nothing. Might even have gotten a bad replacement resistor. Do you have a video on the rear air?
I have a 2005 Tahoe. It appears the blower motor and resister were changed when the AC selector was changed by the previous owner. The fan speed selector is going up and down. The green fuse appears to be in good shape. If all those are working, what could be preventing the blower from working?
hey I know you made this video 4 years ago but I need some help. just bought an 01 tahoe and the rear blower motor stays constantly running until I shut the car off.found out it's the blower motor resister so ordered a new one today and the one I recieved is a little different since the old resister has a plug with 3 wires and a 2nd plug with 4 wires and the new resister is just 1 7 pin connector and I dont know how I'm supposed to wire the 2 connectors into 1.the new harness I got is not color coded and only has black and white wires and I cant find an actual diagram or anything helping me in knowing how to wire this correctly.plz give me any advice you can so I can get some heat going in this car and able to control it.thank you for the time
July 13, 2019, I took my 06 Chevy Tahoe to precision tune for an oil change, remind you My A/C was working good when I drove in, but I got ready to go, I'm having the same problem that the video above shows...I was so mad because I know for a fact they did something to my blower. I would like your input on this situation. Thanks
2005 Suburban I get no heat from dashboard vents. Heat comes out defrost / floor vents only. A/C comes out all vents. I tried soft and hard hvac reset does nothing. Any direction at this point.
My2013 suburban has a similar problem. On long trips it will stop blowing out the vents but I can hear the motor rumbling in the dash still. Is this a motor going bad or a blend door issue?
I have a 2003 Chevy tahoe and the doing the same thing ac not working in the fornt but the rear is working and the Cluster goes off and on along with the fornt left Low beam headlight
Mine worked on level 1-4, 5 didn't work and now neither level is working. But when I put it on level 5 I can hear a click by the resistor. Do you think its the resistor?
Will a 05 Silverado be the same my fan was blowing on high only and then it quit blowing High in a couple of days so change that module and it should work right
I. Have. A. 205. Suburban. When. The. Wier. That. Gos. To. The. Power. Module. The. Controls. The. Ac. Is. Plug. In. It. Works. But. You. Cant. Control. The. High. Speed. Or. How. Cold. You. Want.

Great video! Just did this to my 2003 Avalanche. I was thrown off some by the new module vs the old "plug and play." Once I cut and connected the old wires to the new I was up and running again. I decided to just replace the blower fan as well since I was right there.
Just watched your video, I have the same issue on my 2011 Suburban can you tell me if this is the part you used or equivalent. I found it on auto zone website Duralast Blower Motor Resistor BMR012KIT Part # BMR012KIT SKU # 1180723
I have a H2 Hummer my ac blower stays on after turning the ac off and when removing the key. I replaced the blower motor resisters and blower motor . Still the same problem. Is it the control module not shutting the power off ?
Great video, hey, I have a 04 suburban 1500 2wd flex fuel v8 5.3L with dual climate control with Auto for hvac. I installed a new mode door actuator and it doesn't take the calibration, it spins initially but I have no control over it with the ac controller, also the rear doesn't work. I'll appreciate your response. Thanks in advance.
If we replace everything new ( compressor, dryer, condenser,) and just run cold for avg 30 to 45 mins and then stop cooling for another 30/45 mins but just blowing like hot, do your thing according to your experience it will be the element are bad?
Wound up replacing motor module, fixed problem. But I did not see a DC voltage on control wire like you had only had a few millivolts . I took up my portable LCD scope and could see control signal PWM . Wonder why I did not see the DC signal you did , was your meter referenced to GND for that reading ?
Loved the video. Prior to watching it I thought to myself that I should start at the blower itself and work backwards to see where something is "lost". Wasn't sure what I was looking for but I figured I would need some voltage on the lead to the blower motor and a ground. I was almost certain that the control module (resistors) would be the problem. Funny thing is once I stuck the T pin into the purple and white connector, the blower turned on. How after 18 years did it become a loose connection issue? If the problem comes back, will probably need to replace the control module. Would be nice to know where you got your ground for your PowerProbe or the multimeter. I tried the parking brake at first and it didn't work. I then found a shiny metal plate above the parking brake and it worked. Thanks for the video. My '05 did not have 2 plugs. It had a single plug for all 5 wires. There was also another plug that piggy backed off the control module plug. No idea what it was for. Not connected to anything. Made it easy to test for ground and battery power (no need for T pin).
I have a 2003 GMC Yukon XL and I changed the battery and the blower motor stays on even when the car is not turned on the blower motor invents work I pressed the buttons to change the directions and the power of the blower and seems to get louder and work fine is the panel gone not the actuator?
Question, I looked at your schematics in the video and the purple wire looks like it goes directly to the control module on the dash. I get 4.8vdc on the purple wire and it drops to 2.1vdc when I adjust the fan speed. When I unplug the wires from the back of the control module on the dash I still see 4.8vdc at the resistor module and I get the same voltage at the connector when it’s unplugged at the dash. What am I missing here?? Thanks in advance!
I installed the new relay correctly and now it's not blowing air at all..? Before, the problem was that it kept blowing air after the key was turned off.
Question I have 2003 tahoe blowing hot air i checked the ac Compressor and its not Spinning. i put power to it and it works blowes cold air direct i put a need control M and blower also Resistor still nothing Compressor does not go on
Do not need to cut any wires, remove the 3 wires from original connector and the 3 pigtail wires from the new harness with jewelers screwdriver and swap the 3 wires.
I saw a vid where a guy attempted to do what you're saying but when he pulled the wires out of the original connector there was still some kind of metal contacts on them. He cut those off and just ended up butt-splicing. He didn't try to open the new connector. Can you elaborate more on this?
My chevy tahoe in the front it only blows thru the windown vents not thru the front dash, and the rear dont blow at all is the front and back two different problems or could be one issue
Love your videos because your a little more detailed on them. The majority of the techs on you tube for instance they use scopes but they don’t show how to hook them up. That would really help out the new generation of techs coming into the industry. I know this didn’t need a scope. But your detailed on the repair without a long video. Keep up the good work brother.
2006 Suburban, helped me and saved money. Thank you! Much appreciated!

Thank you for posting such a great, informative video. I definitely subscribed.
Great video I have a question my 2002.Chevy Silverado a/c is not flow from the front vent
How I can fix the problem
Thanks.
Thank you!
hey I know you made this video 4 years ago but I need some help. just bought an 01 tahoe and the rear blower motor stays constantly running until I shut the car off.found out it's the blower motor resister so ordered a new one today and the one I recieved is a little different since the old resister has a plug with 3 wires and a 2nd plug with 4 wires and the new resister is just 1 7 pin connector and I dont know how I'm supposed to wire the 2 connectors into 1.the new harness I got is not color coded and only has black and white wires and I cant find an actual diagram or anything helping me in knowing how to wire this correctly.plz give me any advice you can so I can get some heat going in this car and able to control it.thank you for the time
Thanks bro.great video good help
Where did you find an interactive online wiring diagram like the one you just showed us in the video? That's super useful!

I get no heat from dashboard vents. Heat comes out defrost / floor vents only. A/C comes out all vents. I tried soft and hard hvac reset does nothing. Any direction at this point.
Tinning and soldering shrink rap here can be done? Wire connects 2@ 16/14 wire, 1@ 22/18 wire... seems faster....
Awesome video where did get this part
My2013 suburban has a similar problem. On long trips it will stop blowing out the vents but I can hear the motor rumbling in the dash still. Is this a motor going bad or a blend door issue?
Shrink tubing was not used why is that? But otherwise nice job and thank you
I have a 2003 Chevy tahoe and the doing the same thing ac not working in the fornt but the rear is working and the Cluster goes off and on along with the fornt left Low beam headlight
Mine worked on level 1-4, 5 didn't work and now neither level is working. But when I put it on level 5 I can hear a click by the resistor. Do you think its the resistor?
I'm having the same issue with my 2002 chevy avalanche. can you help with the diagnosis ?
Is it the same thing for a 2003 Suburban? How much for the module?
We're you located
My rear aux only works on high (3) how do I get it to work on 1-2
I have a thumping sound coming from my passenger side, what could the problem be?
Sounds like an air door actuator.
@@ADVANCEDLEVELAUTO
Is this why on the driver side i get hot air and cold air on the passenger side?
part # for the blower motor itself?
Is that coming on a 05 Silverado sounds like mine is having the same problem it was blowing and just on high and now it don't blow it all
Will a 05 Silverado be the same my fan was blowing on high only and then it quit blowing High in a couple of days so change that module and it should work right
From your step by step video I was able to fix my own Yukon!! Girl Power!!!
If you cut the wires at different lengths you won't have a big bulge in your harness
Thanks man, I didn't need a new module but I traced the wires and one was loose. Now I'm back to working AC. Your the man
Front and back air blows but doesn't stay cool. Also have weird noise from area you just showed
Thank you for showing the cover removal and mentioning the sizes of bolts.
That's what I'm talking about. To the point and what does what. Nice video. Appreciate the short and sweet video.
Great work mate

Great video! Thanks for helping me fix my resistor. I followed your video to the letter and nailed it with no mistakes.
Nice instructions, nice tools, ( to remove the module, 5.5mm socket?? )Thanks to all of you..

My 2004 Chevy Tahoe z71 4x4 has same problem...Did your blower blow a bit but not a LOT when you turn up heater/ac???

Thank you so much! awesome video i fixed my Chevy Suburban 2006 Z-71 in 15 minutes.
Fixed the problem in my 05 trailblazer
I installed the new relay correctly and now it's not blowing air at all..?
Before, the problem was that it kept blowing air after the key was turned off.
I have a 2011 gmc and im having that problem blower not working would it be similar on the 2011?
Will this resistor work on the rear blower in a 2003 Tahoe? It has auto AC and the resitor looks identical to the one you were checking on the video.
Question I have 2003 tahoe blowing hot air i checked the ac Compressor and its not Spinning. i put power to it and it works blowes cold air direct i put a need control M and blower also Resistor still nothing Compressor does not go on
Would it be the same thing for a 2005 Chevy Tahoe. It has the same type of ac control screen.
Just wanna say that YOU’RE THE FUCKING GOAT 🐐. THANK YOU‼️

Also having wires exposed like the defeated the purpose of not cutting them all at once and then having them touch after you striped them
Perfect- step by step analysis which allowed me to repair my truck without purchasing unnecessary parts. Thank you, Thank you, Thank you!
I just change it from old style now the driver side blow hot air and pass side blow normal air. Weird
This video helped me fix our 2005 Suburban for about $34.00 I appreciate you for taking the time and sharing knowledge.
Great video, how do i change my display from Celsius to Fahrenheit
Wonderful video thank you once again God bless you ✝️✝️✝️
My chevy tahoe in the front it only blows thru the windown vents not thru the front dash, and the rear dont blow at all is the front and back two different problems or could be one issue
I am having the same problem and by far this has been the best video I've seen regarding the repair needed to resolve the problem.
Kill the music in the back for every one please hard to focus on what the hell your saying
Great video man. Thanks for knowledge brotha 👍🏼
would that part being bad also cause the fan to start and stop as well as run fast and slow at times? just wondering thanks
Great video.. You just saved me some money.. Thnk you so much...

Thank you very much for your help. We have the same vehicle and I ordered the same Parts you did and I'm looking forward to fixing my truck.
Mine is blowing air but it's not giving correct temperature just blowing
What if I have power and ground yet no signal on the purple signal wire
Great video Eric, I wish all Blower Resistors were that easy to gain access to as this Chevy!!
I'm hopeing thats whats wrong whit my avalanche.....
Followed your advice to fix the blower on my '04 Tahoe, thanks!
Awesome! Thanks for watching!
It's blowing in the front but nothing is coming out the front
I know this an old video. My 05 Escalade has the same issue. I replaced the blower and the resistor and still no air blowing. Any ideas?
Did you check the fuse under the hood?
How can I find all the kit?can someone help me please
Why does switch for fan in back work but not in front
I have a 2006 Denali , THANK YOU so much for this awesome video. It helped me so much I relaced this piece you spoke about and boom... my AC works!
Awesome! I’m glad I could help!
Bro why tf is the music blasting?
