Is there a way to test a blower motor resistor?

Place one lead of the Ohmmeter on terminal 1 of the resistor. Place the other lead on terminal 2 and check against specifications.

How do I know if my blower motor fuse is bad?

How to Test a Blower Motor

  1. Use voltmeter or ohmmeter to check for a blown fuse. If you find one, replace it.
  2. Start car and see if blower motor works. If fuse blows again, check for loose circuits.
  3. If the circuits are in good repair but the blower motor keeps blowing fuses, replace the blower motor [source: You Fix Cars].
