Hi, I'm Mike 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're going to show you how to replace the blower motor resistor in this Dodge Ram. This one is a 2008, but this procedure is similar for 1994 to 2009 Dodge Rams. You'll need a new resistor from 1AAuto.com and a Phillips screwdriver.
Your blower motor resister is located under the dashboard on the passenger side, just below the glove box. We'll disconnect the electrical connector and remove these two number two Phillips head screws. Remove the resistor from the bottom of the HVAC box.
Here we have our old part that we removed from the vehicle and our new part from 1A Auto. As you can see, they're identical. We have this ceramic heat sync on the part of the resistor here. Same four pin connection at the bottom, as well as the same two bolt holes. You'll see that ours has become overheated. You can see that this ceramic is cracking. We actually have a good chunk of it that's come off here. This is a good sign that our resistor is getting too hot, possibly because of all this corrosion build up on the copper terminals at the bottom. If these go bad, it can cause operation of certain fan speeds or the fan to fail completely, so be sure to check out this resistor before you go and replace a fan.
Install the new blower motor resistor into the bottom of the HVAC box. Start your two Phillips head screws. Tighten them down with your number two Phillips head screwdriver. Reconnect your electrical connector.
Thanks for tuning in. We hope this video helped you out. Next time you need parts for your car, please visit 1AAuto.com. Also check out our other helpful how-to and diagnosis videos.

Brought to you by 1AAuto.com. Your source for quality replacement parts and the best service on the internet. In this video, we're going to show you the location and how to replace your blower motor resistor. If your truck, the fan works, but maybe it doesn't work on certain fan settings like low or second, that's usually that your resistor's gone bad.
A pretty easy replacement. Just need a Phillips screwdriver. Your blower resistor, you can see it right here, along with two Phillips screws. It's pretty easy to access, although I'm going to film from right down here. Now first, there's a tab on the inside of the harness. Push the tab in and work that down. Then there are two screws. Original, new one from 1A Auto. You can see pretty much all the same. The connection is exactly the same. It's going to go in, both in, and function just like the original. Now install our new one up in there. Reconnect the lead. Turn the key on. Blow, two, three, four.

The part fit perfectly and the supplied video from their website (app) made the repair quick and easy.
part woked as it should and arrived quickly
Works great! Thanks
Arrived on time and took 2 minutes to replace. Been a few weeks now, no issues.
This retirement part solved the malfunction in the blower and installed easily. It had been in for six months now and works like it should. The old one was visibly broken upon removal.
Product came in expected time , and was easy to install and worked as expected AC and myself are now all Chilling ??
Working like new
Honestly, I have very few words, but you guys Rock!! Thank ?? you for excellent, excellent service ?? ?? ?? ??! Timely delivery! And even an installation video.
Excellent! Looked and fit exactly like the original. The instructional video is how I found the part I needed in the first place. This made troubleshooting and installation a breeze and let me know that i only needed a resistor and not the entire blower and resistor kit. I did try to find the part locally just because I was already working on my truck that day but only found the wrong part locally and it cost significantly more mostly because it wasn't the right part. So I ordered it and it arrived on the date promised. I got it installed in a few minutes and yay, had air blowing out at low, medium, high levels instead of just blowing on low but sounding like it was on high. Very nice to have cold or warm air blowing when I need it! I was very pleased with the quality and excellent price of the part I needed. I will definitely use 1A Auto for future needs! The shipping was free with my purchase. Very great!
