Hello there I have a 2007 hyundai accent that the blower motor has stopped working. I have checked all fuses and they are good. I have check the relay it is good. I have checked the switch it is good. I have checked the motor it is good. I have tried tapping on the motor to see if it comes on and nothing happens. I have put it on speed 4 to by pass the resistor and it still doesn't come on. Could it be the switch that is bad. I need help please. Some advice would be greatly appreciated.

 

I gotta tell ya , ya got me confused.
If you checked the motor and the switch and they are good, how can they be bad?

Seriously, the way to check the motor is to remove it and supply a direct power and ground to the motor. If it is good it will spin almost out of your hand.
Any slower, replace it.
Now if that test passes you know the motor needs to get full power to it for hi speed. The possibility of high resistance in the power supply to the motor could involve the switch or a module if your vehicle has automatic climate control.

 

Maybe I am not testing the switch right. I did test the motor and it spun out of my hand.

 

Can you try the motor test with the power coming from the usual source? That will give you some idea if the regular power path is not working correctly.
