How to test the blower motor on a Honda Civic?
NOTE: If you have already tested your Honda Civic’s blower motor (and it’s good) and need to just test the blower motor resistor (known as the blower motor power transistor), then the following tutorial will help you test it: Blower Motor Resistor Test (2001-2005 1.7L Honda Civic). Contents of this tutorial: How The Blower Motor Works.
What causes the blower motor to stop working?
8 times out of 10, when the blower motor stops working, it’s the motor itself that has fried but not always. Other components that can fail, and cause the blower motor to stop working are: Blower motor fuse (located in the under-hood fuse box). Blower motor relay fuse (located in the under-dash fuse box). Blower motor relay. Blower motor.
Where is the relay on a Honda blower motor?
The blower motor relay activates (since relay terminal slot #1 is always connected to chassis Ground). The relay closes the power feed circuit to the blower motor and the BLU/WHT (blue w/ white stripe) wire of the blower motor harness connector now has battery power (from the #12 fuse of the under-hood fuse box).
Where is the power transistor on a Honda Civic?
Disconnect the blower motor resistor (power transistor) from its harness connector. The power transistor is located under the right side (passenger side) of the dash. IMPORTANT: Before continuing on to the next steps, verify that your Honda Civic’s ignition switch is in the Off position.

Where is the fuse on a Honda blower motor?
Fuse #14 of the under-dash fuse box powers up and then feeds the number #2 terminal slot of the blower motor relay (on the under-hood fuse/relay box). Fuse #14 is a 10 amp fuse. Fuse #14 (of the under-dash fuse box) is the one that feeds battery power to the blower motor’s coil.
How can I test the blower motor relay?
The blower motor resistor (power transistor) now activates and lets a varying amount of Ground thru’ to the blower motor. This varying amount of Ground is what controls the blower motor fan speed. Testing the blower motor and the blower motor relay isn’t hard. Let’s start with the first test.
Where is the fuse for the blower motor?
Blower motor fuse (located in the under-hood fuse box). Blower motor relay fuse (located in the under-dash fuse box). Blower motor relay. Blower motor. Blower motor resistor (known as the power transistor). With this tutorial’s, you’ll be able to test them all and get to the bottom of the problem.
