Great product, needs a warning
Everything I bought from 1A Auto has been perfect in addition with the helpful vidoes, I have been able to make repairs in my garage for the fraction of the cost. This product came to me very quickly and it was in perfect condition. The only thing is that with my year model and type of truck the installation video had a different part that he was installing. This product requires you to cut the three pin connector from the climate control and solder to the red, black, and purple wires on the product. Just wanted to give you guys a heads up. Thank you for the great product at a great price.

gm blower resister
I am very satisfied with the blower motor resistor and jumper harness everything was the same as the factory with the exception of it being the updated resistor which worked out to be great.

Inadequate wiring instructions
I still havent installed this part for Im not sure what to do with the additional wires.

AC working Great!
The part was perfect for the job! Great price! I would buy it again, and will contunue to buy parts from 1A. My wife was happy to have A/C running again.

It worked great.
Easy to install and worked perfect. Quick fix. The hardest part was to solder the three wires to the old wiring harness but other than that, no problem. I recommend the manufacture supply a jumper to eliminate the need to solder and wires.

My review
The product was priced lower than most other online stores. The quality is very good, and is performing as it should be. The only minor complaint I have, is no instructions were included. The online video tutorial did not include how to connect the 3 jumper wires, but I figured it out anyway. Other than that, great product for a great price!

Fast & Affordable
My AC stopped working on my 2006 GMC Envoy. After checking all the fuses I determined it had to be the Blower Relay. There were lots of choices online but I found 1A had the best price and free shipping. Their website was very easy to use and the product arrived in just 3 days. I am very happy to have my AC working again. Thanks 1A.

2004 Chevy Trailblazer Resistor Motor
The part works perfectly. The fitting was slightly off as my 2004 Chevy Trailblazer has a different wire harness port. But once I cut off the wiring harness from the new component from 1A and splice the wires it worked perfectly. Thank yall!

1A Auto parts
I needed a blower motor mod replacement, and priced one at my local auto store at $116. 1A auto had the same part for $42 which arrived and fit as expected. Great value, and ordering / shipping was a breeze.

Blower resistor
Shopped around forever to find a new resistor for my truck. The dealership wanted twice what I paid for on 1 A auto for the same part. The part I received from 1a was an aftermarket production that I had to require myself, at first I went to the dealer for a plug and play resistor and found they had the exact same part for twice the price and I would have had to rewire as well. Very please!

Great Product; Wrong Installation video
I have a 2003 Chevy trailblazer EXT. I ordered this resistor because my blower would not turn off. Research the part and watched the install video. Video waz clear and looked easy to remove and replace. Ordered the part and it is different from the original. Unfortunately the video does not show how to install the ordered part. Called 1aauto support line, which instructed me to cut wires in order to install to new part. They were very helpful but the video should be changed to reflect the part. Once installed part works great.

Blower motor
It arrived in a timely manner and installed as advertised but it does not come on right away it takes about two blocks or so before coming on. I dont think this is the way it should work. But it does work.

Exactly what I was looking for! Installation was super fast and easy. Fast shipping to Canada as well. My Envoy, which has automatic climate control, finally has a working blower again.
