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.

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.

Works perfectly.
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!

Great product. East to install.

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

Part arrived on time. 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. Jim

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 have a 2001 2500hd silverado and I'm having an issue with my heat. For about the past 6 months my ac/heat would stop blowing and then start back up. A few days ago it stop completely. All y fuses are good any suggestions as to why it stopped workin

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