Air conditioner blower isn't working. What could the problem be?

Hello, You are on the right track already, and there is a fuse for the blower motor that you can check. Look in your owners manual for the fuse location and position, check the fuse by replacing to be sure the installed fuse is good. Also, the blower motor resistor may have failed, and this will cause the blower motor to fail as well. Fuse first, check the resistor for damage second, then test the blower motor.
