How to test Honda Civic blower motor resistor?
The following step-by-step tutorial will show you how to test the blower motor resistor (power transistor): Blower Motor Resistor Test (2001-2005 1.7L Honda Civic). CASE 2: The blower motor DID NOT come on when you turned the key to the On position. This test result tells you that the blower motor is fried and needs to be replaced.
When to replace the blower motor power transistor?
If the resistance IS NOT within specification, we can conclude your Honda Civic’s blower motor power transistor is bad and needs to replaced. Now, if the resistance is within specification, then we need to continue on to the next test (which is testing the power transistor diode).
Why does my Honda Civic blower not come on?
This test result tells you that the blower motor is OK and that the reason it’s not coming on is due to a possible problem with the blower motor resistor (known as the power transistor). Thankfully, you can test your Honda Civic’s blower motor resistor and thus be absolutely sure that it’s fried and behind the cause of the ‘no blower’ condition.
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.
