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 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 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 Also check out our other helpful how-to and diagnosis videos.
