Hi, I'm Mike Green. I'm one of the owners of 1A Auto. I want to help you save time and money repairing and maintaining your vehicle. I'm going to use my 26 plus years experience restoring and repairing cars and trucks like this to show you the correct way to install parts from 1A Auto.com. The right parts installed correctly, that's going to save you time and money. Thank you, and enjoy the video.
In this video, we're going to show you blower motor replacement on this 02 GMC Sierra. This procedure is exactly the same for any 99-02 Silverado or Sierra as well as 2000-2002 Tahoe, Suburban, Yukon, Yukon XL. It's also similar for the 03 and up trucks; 03 to 10 or 11 trucks that have the twist in style motor. The only tools you need are a 7 millimeter and 7/32 inch sockets with a ratchet and a small extension.
On the passenger side, there are four 7 millimeter bolts to remove: one there, one in there, there's one up in that hole right there. I can't really video it. Then it'll be here closer to the gas pedal. There is one right there. Once you removed those bolts, just reach in and pull it down and out of the way. Up underneath, this was the shield for the fan. There's a bolt here. One, I can't really film directly opposite of it. Feel up in there for it. You got 7/32 bolts. You want to remove them both. You can see I have a little extension on my racket and socket. I really need that.
Okay, just fast-forward here. I'm turning the wrench. Then, eventually, it comes out easy enough so I can put my hand up in there and I try to wrest the way out with my fingers. This is the bolt. This one here. Okay, you can see- you can't see this. Now you could see up in there is your connection, your harness connection. You can usually just stick here; your finger in there, and press the tab and pull that out. It allows your shield to come down.
Looking up in there, at this point, there's actually a tab right here. You need to pull down on that tab. Okay. You reach out there with this hand and this finger. I'm pulling down on the tab, and then I'm twisting the motor. Twist. Comes right down and out.
Apologies for that camera work. I didn't realize until after I shot that I didn't get a very good view of that. Basically, you pull down on that tab that I showed you before and then you twist the motor. It will be counter clockwise to then it'll come down and out.
This truck is a video mule. I'll just put the original back in because it's exactly working fine. You just push it up, work it up in there. A crate gets in the way here. Okay. Push the motor up in. Then spin it. Okay. It looks nice and secure. Now get the wire through your shield, and then connect it. You can do that either way. You can put the shield up in there first. I find this just a little bit easier. Shield. Shield in place. Strap this bolt first. You reach up in here. Feel your other bolt. You do it by feel. Get that and started. I'm going to take them out.
Okay. The final part is to put your cover back in place. You want to push it up in there. You push it; it gets the firewall first. I'm sorry about shaking around a little bit here, just trying to film with one hand and push up in there with the other. Push the front of it up in the end first. Then make sure you have everything lined up. Okay, as you could see here, there's the passenger side out the holes. Make sure those are all lined up. Then start your end bolt here. Then I recommend starting the one over near driver's side. Once you have those lined up, then the other two middle ones go in pretty easily.

Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and the next time you need a part for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace the blower motor on this 2002 Chevy Suburban. The items you'll need for this includes a new blower motor from 1AAuto.com, a 7mm socket and ratchet, a 7/32 socket, and a flat blade screwdriver.
You want to start off by removing this panel below your glove box, and it's held in by these three, 7mm bolts right there. We'll just fast-forward as Don removes those, and you really only have to remove the two on the outside. The one towards the center of the vehicle, you can just loosen.
Now your resistor's held in with two, 7/32 bolts. Just go ahead and remove those. Now push the tab on this harness and disconnect it, and then up here, on your blower motor, is the other end of your resistor harness. You want to just push the tab on this and disconnect it. Your blower motor is held in by this tab. You just want to use your flat blade screwdriver, pry the tab down, and twist the blower motor counterclockwise, and that will pull down and out.
On the left is the old blower motor; on the right is the new one from 1A Auto. You can see they're very similar, and they'll fit exactly the same. Take your new blower motor and just push it back up into place. You want this tab to slide in right here, and then turn it clockwise, and it will lock into place.
Now reconnect the blower motor resistor. Push the resistor back up into place, and replace those two 7/32 bolts. We'll fast-forward as Don tightens those up. Now, reconnect your resistor harness. Now push this panel back up into place, and then replace those three 7mm bolts. Just tighten them up, and we'll fast-forward as Don does this. Once you've done that, you're all set.

Great Price and near perfect fit

After I purchased, this came to me within 3 days. I already had my old motor out, so the truck was opened up and waiting for the install. I watched the install video provided here. My truck has a center console, so it wasn't nearly as easy to do as the video. Aligning the new motor took 30 minutes of negotiating angels. Also, the place the wiring harness plugs into is offset about 30 degrees from where it is on the old one. Fortunately there was enough wire length from the vehicle to compensate. Overall, the install was more difficult than I thought it would be, but the quality and price of the motor made it worthwhile. I'd definitely do this project again and purchase from this company.

Great product and great video. Started with RockAuto. Their product did not come close to working or fitting even after I provided both the electrical and mechanical fit up spec. I also had to pay for the return shipping. So much for the competition. Again thanks for the great service.

Received parts exactly when they were scheduled to arrive. The installation video definitely helped. It took some work to install only because of tight spaces and big hands. Otherwise all went very well. Will definitely purchase my parts here again. Thank you for such great service!

It fit as promised. It was the best price out there and now I have heat in my truck and better A/C as well. The amount of the air coming out of my vents went up 4-5 times and I haven't felt this much air coming out in several years. Installation was easy. Thanks.

Got here as promised, the installation was a breeze after watching the video.
One thing though, if you have a handicapped left hand, like I do, you may want to get some help as this is left hand intensive.

Heater Blower motor with Fan Cage

I viewed the A-1 Auto video prior to trying to install the blower. All parts were removed with little trouble. I then spent over four hours trying to install the new blower. IT DOES NOT Fit!!! It looks exactly like the unit removed except the electrical connection is in a different position on the base and the new connection is horizontal and not vertical like the old unit. I measured the outside diameter of the old unit and the blower base appears to have a slightly larger diameter. That would account for it not fitting back in the AC/HEATER housing. What do you suggest? I'm going to NAPA and get another Heater Blower and return this one to you, unless you have a suggestion to resolve the problem. No AC in Georgia in the summer is not an option.

This was just as good as factory blower. Easy install and very quite compared to one that the bearing squeals. My install is a GMC Sierra Denali Quadrasteer 2002. Great service and prompt and fast delivery.

Not an "Exact Fit" as described.

The vehicle is a 2002 GMC Sierra 2500HD. The fan does work but if like like replacement parts to fit like original this is not the part for you. The electrical connector is turned about 25 degrees towards the firewall making it that much harder to connect in an already tight space. If you want put the insulated cover back on you'll have to modify it. Customer Service tried to justify it not being an exact fit as advertised by claiming that theirs looks the same as other after market fans. Sorry but not fitting correctly is not an exact fit and if others are also wrong maybe correct your product and be better than the others!

The fit was tight but good. The electrical connector was in a slightly different location but worked fine. It's been installed now for ~ a month and I'm picking up a slight high pitched whine that wasn't there when it was installed but it hasn't gotten loud enough to be real concern. I'll monitor it and update this review if needed

Perfect fit
Would recommend 1A to all my family and friends
1A auto has been my go to parts store for years now. I've never been disappointed.
Let me tell you just how good they really are.
Not to long ago I ordered a set of fuel injectors from them. Was supposed to be delivered on a Monday. After it had not been delivered by Wednesday, I called. They sent another set out that day next day delivery with a return shipping label for the first set if it did finally deliver. Three weeks later here comes the first set. I returned them and have never been so pleased with a customer service team as I have been with 1A.
Love your videos. Keep up the good work.

Fit up perfectly, replaced resistor and pigtail also because the old motor was pulling too much electricity and burned it out too. It's so nice to have 1, 2,3,4,5 fan adjustments back again. Thank you 1A auto!
If I can do it, so can you!

I would start with the resistor first. If that doesn't fix it (and the fuses are all good), then replace the blower motor.
