TEST 2: Applying Power And Ground To The Blower Motor
Now that you have confirmed that the current draw of the blower motor is within specification in TEST 1, our next step is to apply battery power and Ground to it and see if it runs.
You will need to remove the blower motor from itch location to be able to easily apply battery power and Ground to it. You'll also need to use jumper wires for this test. The jumper wires should have crocodile type terminals, like the ones in the illustration above, too easily and safely perform this test.
Once the blower motor gets power and Ground, it should run without any loud bearing noise. If a blower motor does not run at all, then you can conclude that it is defective.
Let's get testing:
Disconnect the blower motor from its electrical connector.
The connector has 2 wires. The blue with white stripe wire (BLU/WHT) wire supplies power and the blue with black stripe (BLU/BLK) wire supplies Ground (via the blower resistor and blower switch).
Apply battery power to the blower motor's male spade terminal that connects to the BLU/WHT wire of the electrical connector.
Apply battery Ground to the blower motor's male spade terminal that connects to the BLU/BLK wire of the electrical connector.
The blower motor should run.
Let's examine your test results:
CASE 1:The blower motor ran and ran without any loud bearing noise. This test result let you know that the blower motor on your 2.0L Honda CR-V is functioning correctly, especially if you have confirmed that it's using less than 40 amps in TEST 1ne.
CASE 2:The blower motor ran but ran with worn out bearing noise. With this test results You can conclude that the blower motor is defective and needs to be replaced. The loud bearing is usually due to defective bearings or worn brushes.
