Testing The Blower Motor (1995-1997 2.3L Ford Ranger)

TEST 2: Applying Power And Ground To The Blower Motor

Applying Power And Ground To The Blower Motor. How To Test The Blower Motor (1995, 1996, 1997 2.3L Ford Ranger)

In this test section, we're gonna' manually apply battery power and Ground to the blower motor.

What we're looking for is for the blower motor to run and run without any bearing noise.

Even though the blower motor is in an easy to access place in the engine compartment, you probably need to remove it to connect your jumper wires to it.

IMPORTANT: If your 2.3L Ford Ranger's blower motor runs, but it did not pass TEST 1, you can conclude that it is defective and needs to be replaced.

Let's get started:

  1. 1

    Disconnect the blower motor from its electrical connector.

    The connector has 2 wires. The pink with white stripe (PNK/WHT) wire supplies power and the orange with black (ORG/BLK) wire supplies Ground (via the blower resistor/blower switch/vent switch).

  2. 2

    Apply battery power to the blower motor using a jumper wire.

    You'll be applying power to the male spade terminal (of the blower motor itself) that connects to the PNK/WHT wire of the electrical connector.

  3. 3

    Apply chassis Ground to the blower motor.

    You'll be applying Ground to the male spade terminal (of the blower motor itself) that connects to the ORG/BLK wire of the electrical connector.

  4. 4

    The blower motor should run.

Let's take a look at your test results:

CASE 1: The blower motor ran and ran without any bearing noise. This is the correct test result and tells you that your Ford Ranger's blower motor is not defective.

CASE 2: The blower motor ran with a lot of bearing noise. This test result tells you that the blower motor is defective and needs to be replaced.

Worn out bearings will cause the blower motor to use more current. This excess amperage draw will cause the blower resitor and/or the blower switch to burn out.

CASE 3: The blower motor did not run. This test result tells you that the blower motor is defective and needs to be replaced.
