Can you test the blower motor resistor on a Ford Explorer?

Can you test the blower motor resistor on a Ford Explorer?

Thankfully, the blower motor resistor on your Ford Explorer (Ranger, Mercury Mountaineer) can be checked with a few simple continuity tests. With the help of this tutorial, you’ll be able to test it and say: ‘Yes, the blower resistor is bad’ or ‘No, the blower resistor is not fried’.

Where to buy a blower motor resistor connector?

You can find the link to the connector in this section: Where To Buy The Blower Resistor And Save. NOTE: All of the continuity tests, described in this test section, are done on your Ford Explorer’s (Ranger, Mercury Mountaineer’s) blower motor resistor and not on its connector.

How to test the a / C heater blower motor?

How To Test The A/C Heater Blower Motor (Ford 4.0L). The component that makes it possible for the blower motor to run in the 3 speeds lower than HI is the blower motor resistor assembly. If you have already removed the blower resistor assembly from your Ford Explorer (Ranger, Mercury Mountaineer), you know that it’s made up of 3 resistors.

What should the resistance of a blower motor be?

Your multimeter should register a resistance of about 0.2 to 0.3 Ohms ( Ω ). This test also test the continuity of the blower resistor thermal fuse. IMPORTANT: There’s a good chance that you won’t see exactly the resistance values I’ve listed (on your multimeter).

How does the resistor on a blower motor work?

A blower resistor uses resistance to control the speed of the blower motor. In high speed, the resistor is bypassed and power is fed to the motor directly from the switch. This illustration shows a typical blower resistor, specifications and test procedures vary between different manufacturers.

Where is the blower motor resistor located on a Ford Escape?

In the 2008-2011 Ford Escape, the resistor is located behind the glove box on top of the HVAC unit air duct. It’s held by two screws and is easy to replace. See the photo. In the 2008-2011 Ford F150 the blower motor resistor is also located behind the glove box, but is installed in the right side of the plastic air duct.

What to do if your blower motor is not working?

Generally the wires going to the resistor are: Check the connections for the setting that’s not working. If the connections are good and the plug and or resistor terminals aren’t rusted then try replacing the resistor with a new one. For some reason it’s a dealer item and won’t be in stock at your local parts store.

How do you check the fuse on a blower motor?

First check the fuse and all connections. Second, check to see if there is any power at the blower motor. Place two large straight pins in the plug of the blower motor but leave the blower motor plugged in. Place a voltmeter across the two pins.
