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 show you how to replace the blower motor resistor. This is the device that controls fan speed. If you find, in your Escort, that you turn the fan on or turn the A/C or the heat on and say your fan works on speed one and speed four but not two and three or some combination thereof, usually that is a sign that your blower motor resistor has gone bad. It's a pretty easy operation once you find it. You just need an 8mm socket with a ratchet.
On the passenger's side, underneath the glove box, you're going to find the blower motor resistor held in by two 8mm screws. Speed up here, as we use an 8mm socket with a ratchet to remove those two screws. With the resistor down, you can remove the two connectors by pushing. You'll push a tab down and then pull the connectors out.
The resistor's going to go back in this way with the small connector towards the driver's side. We'll speed up here again. We'll tighten up that one screw a little bit and then get the other one started first before we tighten it up all the way. Then you tighten them up firm, you don't want to over tighten them because you could strip the plastic housing.

The heat and air condition fan is controlled by a separate module, called the blower motor resistor. The nature of this component’s job causes it to heat up frequently, which can lead to failure. If your vents will only blow one speed, this is likely the cause. TRQ has a new resistor module made specifically for your vehicle. How to install it yourself in your 2008-12 Jeep Liberty.
