Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we'll be showing you how to replace a blower motor resistor on this 2003 Nissan Maxima. It's a pretty easy operation; you're just going to need a Phillips screwdriver and probably a flashlight.
If you find that your climate control unit and the blower fan only works in high or low, or intermittently goes in and out, most often it's your blower motor resistor. The blower motor resistor is right under the glovebox. I'm removing the clip. Press down on the top and pull out. I'm going to remove the two Phillips head screws.
Here's the old part and the new part from 1A Auto. They're exactly the same and they're going to go in just the way they came out. The tab is going to go towards the front of the vehicle. You can see the notch here in the airbox. I'm going to reinstall two Phillips head screws and reconnect the harness.

Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!
The blower motor resister is here under the dash. Actually, you can just see it, just make out the outline of this white and aluminum looking piece. It's got this little plastic protector so the passenger doesn't kick it. Behind it is the electrical connector. This is the harness it, pull the harness down a little bit. Actually, it might even be easier, we're going to unscrew it, there's two Phillip's head screws. We'll pull the resistor out and then unplug it. You're going to need a stubby Phillip's head screwdriver. This aren't very long. Pull it out. Grab the other one. The resistor will come out of the air box. I got to unplug it.
To reinstall it, leave it unplugged for now. Slide it up in here. There's an alignment tab, and there's a tab in the blower motor box that it has to line up with, so it goes to the front of the car. Slide it up into place. It'll kind of stay in place. The seal will hold it. Take our Phillip's head screws, reinstall them. An electrical connector, plug it back in. Put the harness back up in there. Blower motor resister is replaced.

Watched the installation video, ordered the part. Quick install and worked perfectly!
Good.I like the part is identical to the original
The lady I spoke with to order was very helpful and patient with me while taking the order. The part installed easily and is working perfectly . The video for this problem gave all the answers needed.
This part works great, exactly what I needed. Fast friendly service. From now on, I will be using A 1 auto. The video on how to install it was superb! Thank you A 1 auto!!
Blower wasn't working at all. Swapped out this relay in about 5 minutes and now it works properly.
works good
This worked perfectly for my 2005 Nissan Altima! The A/C worked really well until the fan started turning off and on by itself (it has manual controls), then the fan just went out completely. This part fixed my issue and only took about 5 minutes to replace!
Fits and works perfectly
Took a little while to get it but, put it in and all is well
Excellent product. It works perfectly. The customer service at a1auto is outstanding. Would recommend to anyone.
I have manual temperature controls and it fixed my issue with the AC being on full blast all the time.
