great video, saved me a bunch of TSing time since my 06 SS Silvy had all 3 symptoms no fan, fan on after key off and just randomly working or not. Took about 20 minutes and my htr/a/c fan is back in action!!! Thanks

Thx man!!! My 2004 Yukon Denali front fan started acting up (coming on and off whenever IT felt like it). Used your video n changed out that part. Super easy! Only cost me $55 bucks, 3 wire connectors, n 30 mins. This part at O’Reilley’s was going to cost $250. So glad I found your video. Part looks different n is a little tighter fit but works great! You rock!

Thanks for this. I repaired my GMC 2005 Sierra with auto HVAC today. Your video was quite helpful.

Thank you for your help! Hope it goes as smooth as your video. Lucky its getting warmer out now🙋‍♀️

Thanks. Mine just destroyed my day of hunting. It's a nice day today, but it was sub-sub-zero recently. Drove my 2005 Suburban to go hunting and the blower motor was pegged out on HIGH no matter what setting I was on. I was like, OK, I'll deal later. Well, got to my spot. Turned off the truck, but the blower wouldn't stop. Had to turn around and come home. Found another video to unhook the motor, but thanks to yours I now have the correct replacement part ordered.

Solved. I have a 2005 Silverado Duramax. With Auto HVAC. I bought the AA Ignition brand, AC Blower Resistor Kit, X001NP8WYD, GWA154, OEM#15-81773. It was about $28 on Amazon. The GM AC Delco part at the Chevy dealer was $116-. My problem, the fan ran erratically, or not at all, ALSO this happened during the summer, and in AC mode it might blow cold, cool, or not at all. This part (as illustrated in this guys vid), was the remedy. Works now as expected.

Very helpful I have a GMC Yukon XL and your video is the best

Very helpful, saved a few bucks by doing it myself. Thank you!

Old video I know but my 2006 Yukon XL Denali is doing the exact same thing today and I’ll bet I have frayed wires going to the module!!! Thanks for the how to video! Gonna tackle this after work tomorrow!

thank you for the info in the video such as wrench sizes ....made it a lot more prepared

If you have the patience. You can remove the retaining clip and use a small screwdriver to carefully remove each of the pins from each of the actual clip. You can this for both of the clips. Install them in the same order and reinstall the retaining clip, and you're done. In doing so, you can avoid having to cut and splice the wires.

Great video, you saved me a few hundred bucks

Have to do my self much thanks for the video helped me alot ! .

Thank you for this video! Was a huge help.

I followed everything you said to do and it works great. Thank you soooo much for this.

Great video, thanks for sharing the install steps. Just have a questions, have you had any issues with the replacement part since you installed it? Is it still working?

Thank you for the part numbers !!

Great video very helpful. I did the same thing you did but a couple days later my vent control buttons were not working correctly the air was coming out whichever vent it wanted to. Have you ever experienced that problem?

Mine just went out today in my 06 silverado. Christmas Eve ,eve. Lol. Thanks .

Will that stop the AC from blowing when the vehicle is turned off on a 2003 Tahoe

Hey how are you doing I have a question my AC works but also I think I may be having the same issue as you or issue that you did half my AC only comes out when I’m driving I can’t control it to come to my face to my feet or to my windshield how much is that little part on Amazon

Do you think a additional ground wire would be a help

I'm curious as to before the symptoms presented themselves did you give anyone a jump off or get jumped off with battery cables? I ask as my wife needed to be jumped off and then this exact same thing happened to my Trailblazer and I haven't fixed it yet.

i have an 02 avalanche and all the vents are working nand blowing except for the main front vents? could it be a fuse?

I changed actuator on my 2009 chevy impala now the blower motor runs without the key on or off runs.on high vsn you help

my new part from china i got on amazon, cost 24$ only, but it cycles off, after blowing...i think i got a lemon part. do i have 2caliberate the resistor motor? chevy blazer...............please hepl

What was going on to have to change the module? Mine keeps jumping into Auto Mode and blowing hot air. A\C will run for while then kick off into Auto Mode.

What if my fan isn’t working in heat or AC mode?? Do you think it could still be this problem???

What does that module do. My Chev Yukon has heat slightly coming out year round. And ironically when I flip on the heater it only gets hot at 90°. I already tried pulling the fuse trick that did open the passenger side vents.

i would solder and use heat shrink wrap on those wires . good job

What about an 2013-Silverado, the air works when it want to, and sometimes when you run over an hump, what’s the problem

Thank you My Brother my Tahoe fixed Yep

Mine (an 03 Avalanche) climate control panel died. No display but buttons work. Gas pressures are correct but blows warm only :( thoughts?

I have the same problem with that every vehicles, 3 Chevy Traiblaz and 3 of the Ford Expedition

How did you know that it was the modular instead of the blower motor yesterday my heat and AC worked perfectly fine and now 12 hours later my front blowers are not blowing so do I need to replace the modular or the blower motor

My 03 Tahoe rear A/C Controls don't work for the mid & 3rd row. Nothing comes out I don't even hear anything when tampering with the knobs

What does the blower control module do? Why did you need to fix it? What was it not doing correctly?

Good video. One main question is why didn’t you allow the 2 min relearn procedure for HVAC after repairs made to A/C system

wish I could down and fix mine like that I'll probably have to take it to a mechanic. got a steel rod in back can't get down to fix myself

I have no fan at any speed will this fix my issue? Well as long as my blower motor is OK.

When you have to solder multiple wires, cut each one at different lengths and match to the new wires so you don't have a fist of solder joints on a ball on top of one another and possibly risking a short.

Why did you have to splice ? Does it not have the same factory connection ?

Question ❓did you change the resistor also ❓ or just the wire harness ❓can anybody help please 🙏🏼 I thought I’m just supposed to replace the resistor unless the harness is Fried also do that ❓❓❓❓❓

I have 04 Cadillac escalade and it's blowing air when the vehicals is turned off, like completely off so I have to disconnect the negative on the battery to turn off the blower so is the problem fix ?

I have a 2007 Silverado where I found the original resistor on Amazon and the blower motor will not turn off. If I get the updated resister will that fix it?

I have a 03 hummer h2..the heat or air dont blow ..at all

I have a 06 yukon denali, and I bought a similar resistor and all the connectivity looks just the same as yours. Once installed the fan won't shut off. What else could be the issue? My fan motor is new as well.

you demonstrated how to remove bolts and screw up connectors

did you use OEW part?

The blower fan for the heat will not turn off keep blowing with SUV turned off.

I bought a cheap one off amazon and it goes on and off randomly. I need to replace it with this one.

I have a 2006 envoy g m c and my air work 123 and want blow on 4 and 5 what could be the problem

Looking for the blower control module

Why did you have to cut the wires? I bought an hvac module and it was plug and play. No cutting or splicing cause I bought the correct part.

Please update info on which color wire goes where. Everythinh else is pretty clear just the splicing needs a bit more specifics

When I turn my driver knob the other side temp doesn’t move with it. I have to adjust both of them. How do you sync it where the driver knob will change both side temp?

Anyone have to recalibrate their blend doors after reconnecting their battery?

!! There are different versions of blower motor controllers that Amazon doesn't seem to be able to distinguish between (i.e. does it fit?), so before ordering a replacement take your unit out to examine it in order to make sure you order the correct part. This video shows a connector going to the controller that only has 3 wires or so (and a seperate connector going from the controller to the blower motor that provides various voltages to run it at various speeds; note that high speed is full 12 Volts DC and the controller is not doing anything in this case, as discussed below). This type can be replaced by this Amazon part (which is what is seen in this video): www.amazon.com/PartsSquare-Resistor-Regulator-Replacement-CHEVROLET/dp/B01I28U8WG/ref=sr_1_22?keywords=Chevy%2C+GM+-+Blower+Motor+Resistor&qid=1561655974&s=gateway&sr=8-22 A second type of controller has 7 wires on the connector going to the blower motor controller (in addition to the red and black wire going to the blower motor) . This replacement controller is found here: www.amazon.com/Dorman-973-405-Chevrolet-Resistor-Harness/dp/B003YLMQHC Both use the red and black connector that feeds power from the motor controller to the blower motor. Also, in my case the blower motor was bad too. When only the high speed works the motor controller is bad, and so when the high speed stopped working, that turned out to be the blower motor itself was also dead. My guess is that the high speed blower setting delivers the full 12V DC battery voltage to the blower motor even when the controller is bad; i.e. the lower speeds don't work (lower speeds use the controller's hgh current resistors to lower the voltage and thus fan speed). Figuring out if your blower motor is dead is important, as the price is double at local parts stores. The red and black wire going to your blower motor controller is hot battery voltage. In order to test if your blower motor is working you can jumper that hot voltage to the red and black connector going from the controller to your blower motor (it will be high-speed 12V DC operation). The blower motor in my case twists out, just like a screw (right hand rule), don't go twisting it the wrong direction like I did while trying to reinstall it.

I have a trailblazer 02 and the problem is that the a / c module went off by itself and does not turn on but the light does come on but the module screen does not and therefore the a / c compressor does not turn on you know it can be

2006 buick allure the fan blower won't shut when the car isn't running

Im having some sort of problem I have replaced the actuator on my 30

My ac on 2004 gmc sierra blow cold and will blow hot also

I have a GMC Yukon and my driver side blower and middle blower will randomly stop blowing the AC and start blowing the hottest heat I can image my Yukon can produce. All other vents are blowing AC perfectly. I can reset it by putting my vehicle in park and turning it off and restarting the engine. It will start blowing AC again but can switch randomly. It's not too frustrating til its 109 her in Louisiana and I am on the interstate and have to pull over off the road to restart the engine. My question is how hard is that to fix? Have you ever heard of this happening?

See you did same problem other videos by skipping. How is 1) a three wire plug fitting in the blower made for 2 wire. 2) how are you connecting the newer 5 wire plug to the harness that had 4 on original? ****update**** I got it fixed in a way. The back wire plug 🔌 to blower would just not come off. Too difficult to reach and control so I just cut the plug off new kit and spliced the wires. Obviously if the old connector has problems that won’t work. In the end everything was spliced and it ran properly

Now what if you put in the new blower motor in and the relay and it still won't work

It didn't say was his even blowing at first?

There is some potentially useful information in this. Apparently your replacing the OEM part with a different part that takes a different connector. It would seem the point of the whole video to explain (and demonstrate) precisely which original wires are tied to which on new connector. You just kind of glossed over it. A bit disappointing. You could have said, for example, "...just gotta cut these guys that run up to the spinny guy and take the new guy that comes with a pig-tail/connector guy and then the black guy connects to the grey guy and the red guy connects to the red guy and I should be using wire-nut guys but the guy at the store wasn't McGUYver and he guyded me to the wrong stuff so just stick all these guys together with some peanut butter and jelly or maybe some Elmers Guyloo or Guy's Super Glob Fuggut Stuff. Okay guy, let's see if it works."

Sorry to sound dumb but I came on this video and you didn't introduce what the problem was. I have a 2004 sierra and the heat and cold are off and on all the time. I run the a/c and it will run hot hold all the time. Likewise the heater runs cold and hot. I was going to buy a replacement unit for the dash? Its even worse in the summer at idle when the cool turns to super hot and fluctuates until I start revving the engine?? Any advice?

That’s a blower motor resistor fam.

So you just clump all the wires together and taped them all? This can't work.

Buy yourself a light so we can see properly.

Do not need to cut any wires, remove the 3 wires from original connector and the 3 pig tail wires from the new harness plug with jewelers screwdriver and swap the 3 wires.

Why did you splice the wires it should've just worked with the same fitting ? Also next time when you unplug your ground from your battery After you reinstall start the truck your heater will automatically go to 74 it has to recalibrate itself For about a minute then turn it off Wait 10 seconds then you're good to go. ......

This is not a fix this is a replace. Fix mean to repair. Not replace with a new one.

Why are you pulling on wires like that

where do you start to find out why your blower doesn't work ? thank you

Where’s the duramax content ? I click on videos and u have one video lol

Who this be why my ac isntbworking

Dude, take the ring off before you get near your battery. Yikes.

That's not the control module.

Pulling from the wires on the hard 😖😖 ultimate cringe

Get your self some lights

I didn't see him fixing anything, he replaced a part, Is it fair to say that I'll fix my car by buying another one?

Oh my gawd...did u really pull on that plug like I saw! Lmao wow. First of all, if u had ordered the right part u wouldn't of had to start cutting and splicing lol. 2nd, the name of ur video is misleading and incorrect! The part u put in is a resistor, 2 actually, one is for the 1 thru 4 setting on fan switch and the other is for the 5 setting...when ur blower motor screws up or something is really off in that box one resistor usually blows depending on where ur switch was set when it happened. The panel where your fan switch, temp switch, and defrost/feet/face switch is located is called the "HVAC control module", which is what I was looking for to possibly repair and I ended up here because u mislabeled your video! I'm outta here...don't hurt yourself lol

another narcissist ruining Utube and wasting our time loosening bolts

Dude you need to lay off the Starbucks and take your time and explain yourself better I was waiting the whole time to hear you tell me how much the part cost and you never said it once, don't you think it's important to tell people how much the part costs

I cant trust anyone who uses needle nose pliers to cut wires. More like a hack then someone who even has a clue

Know what your talking about before posting videos. Thats the resistor not the module. Also isnt a original factory ac delco. Its an upgraded aftermarket korean job.
